It provides an engineered mechanical and pneumatic platform for mounting the molbloc, connecting the gas supply, regulating operating pressure and integrating a mass flow controller or other device under test into a complete gas flow calibration system.<\/p>\n<p>The molstic-L is not itself a gas flow reference or flow measuring instrument. Instead, it provides the infrastructure required to operate molbloc-L flow elements under stable and reproducible pneumatic conditions. Combined with a molbloc-L and a compatible molbox flow terminal, the molstic-L becomes an important part of a highly accurate gas mass flow calibration system.<\/p>\n<p>Fluke Calibration offers molstic-L systems in <strong>Low Flow, Mid Flow and High Flow configurations<\/strong>. Single-channel versions accommodate one molbloc-L, while Dual versions allow two molbloc-L elements to remain installed simultaneously. This enables calibration laboratories to cover different flow ranges without repeatedly changing the flow hardware.<\/p>\n<p>The integrated components include a gas supply quick connector, precision filtration, adjustable pressure regulation, a bellows shut-off valve and dedicated molbloc mounting cradles. Downstream connections provide a convenient location for installing a mass flow controller, another device under test or an optional precision metering valve for manual flow control.<\/p>\n<p>At <strong>europascal<\/strong>, the Fluke Calibration molstic-L complements a comprehensive range of professional flow calibration equipment including molbloc-L flow elements and molbox flow terminals.

Contamination of this flow path could change its flow characteristics.<\/p>\n<p>The <strong>Fluke Calibration molstic-L<\/strong> therefore incorporates filtration upstream of the molbloc.<\/p>\n<p>Standard configurations use a:<\/p>\n<p><strong>2 micron filter<\/strong>.<\/p>\n<p>Low Flow molstic-L systems use an even finer:<\/p>\n<p><strong>0.5 micron filter<\/strong>.<\/p>\n<p>This helps protect downstream components and the molbloc-L against particulate contamination.<\/p>\n<p>Clean, dry calibration gas should nevertheless always be used to maintain optimum long-term performance.<\/p>\n<h2>Integrated Pressure Regulation<\/h2>\n<p>After the filter, the <strong>Fluke Calibration molstic-L<\/strong> uses an adjustable pressure regulator.<\/p>\n<p>The regulator performs two important functions.<\/p>\n<p>First, it establishes and maintains the optimum upstream operating pressure for the connected molbloc-L.<\/p>\n<p>Second, it helps protect the pressure transducers in the connected molbox against accidental overpressure.<\/p>\n<p>The regulator range is designed to support the standard molbloc operating pressure ranges.<\/p>\n<p>Stable upstream pressure is particularly important for achieving reproducible gas flow conditions during calibration.<\/p>\n<h2>Bellows Shut-Off Valve<\/h2>\n<p>A bellows shut-off valve is positioned immediately upstream of the molbloc-L.<\/p>\n<p>This allows the operator to isolate the gas supply when required.<\/p>\n<p>Typical applications include:<\/p>\n<ul>\n<li>Changing the system configuration<\/li>\n<li>Replacing a molbloc-L<\/li>\n<li>Connecting another device under test<\/li>\n<li>Performing leak checks<\/li>\n<li>Isolating the flow system<\/li>\n<li>Preparing the calibration bench for maintenance<\/li>\n<\/ul>\n<p>The integrated valve simplifies these procedures and reduces the need for additional external isolation components.<\/p>\n<h2>Dedicated molbloc-L Mounting Cradles<\/h2>\n<p>Special mounting cradles support the molbloc-L elements.<\/p>\n<p>These cradles provide stable and repeatable mechanical positioning of the flow elements.<\/p>\n<p>A professional mounting system is particularly important because the molbloc-L must be connected simultaneously to the gas circuit and to the corresponding molbox measurement connections.<\/p>\n<p>The molstic-L keeps these components organized within a compact calibration platform.<\/p>\n<h2>Device Under Test Connection<\/h2>\n<p>Downstream of the molbloc-L, the molstic-L provides a connection and mounting area for the device under test.<\/p>\n<p>Typical devices include:<\/p>\n<ul>\n<li>Mass flow controllers<\/li>\n<li>Mass flow meters<\/li>\n<li>Thermal mass flow meters<\/li>\n<li>Rotameters<\/li>\n<li>Variable-area flow meters<\/li>\n<li>Gas flow sensors<\/li>\n<li>Process flow meters<\/li>\n<\/ul>\n<p>The dedicated mounting area simplifies the connection of the DUT to the reference flow system.<\/p>\n<p>An optional metering valve can be installed instead when manual flow control is required.<\/p>\n<h2>Calibration of Mass Flow Controllers<\/h2>\n<p>The <strong>Fluke Calibration molstic-L<\/strong> is particularly suitable for building calibration systems for mass flow controllers.<\/p>\n<p>A typical system can be arranged as:<\/p>\n<p><strong>Gas Supply \u2192 molstic-L Pressure Regulation \u2192 molbloc-L \u2192 MFC Under Test<\/strong><\/p>\n<p>The molbloc-L provides the characterized laminar flow element.<\/p>\n<p>The molbox determines the reference mass flow from the pressure and temperature measurements and the individual molbloc calibration data.<\/p>\n<p>The reference flow is then compared with the setpoint, indication or output signal of the mass flow controller.<\/p>\n<p>The integrated molstic-L components provide a clean and repeatable pneumatic configuration for this calibration process.<\/p>\n<h2>Optional Metering Valve<\/h2>\n<p>For devices that do not actively control the gas flow, Fluke Calibration offers optional metering valves for the molstic-L.<\/p>\n<p>These allow the operator to manually adjust the gas flow through the system.<\/p>\n<p>Separate metering valve versions are available for:<\/p>\n<p><strong>Low Flow<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>Mid \/ High Flow<\/strong><\/p>\n<p>applications.<\/p>\n<p>This allows the flow adjustment component to be matched to the required flow range.<\/p>\n<p>Fine manual adjustment is particularly useful when specific calibration points must be established for passive gas flow meters.<\/p>\n<h2>Single molstic-L<\/h2>\n<p>Single-channel <strong>Fluke Calibration molstic-L<\/strong> systems accommodate one molbloc-L.<\/p>\n<p>This configuration is suitable when:<\/p>\n<ul>\n<li>One primary flow range is required<\/li>\n<li>molbloc changes are infrequent<\/li>\n<li>A compact calibration platform is preferred<\/li>\n<li>The application is dedicated to a specific DUT range<\/li>\n<\/ul>\n<p>Fluke currently lists Single configurations for Low Flow, Mid Flow and High Flow applications.<\/p>\n<p>The Single system provides a straightforward solution for dedicated gas flow calibration benches.<\/p>\n<h2>Dual molstic-L<\/h2>\n<p>Dual-channel <strong>Fluke Calibration molstic-L<\/strong> systems allow two molbloc-L elements to remain installed simultaneously.<\/p>\n<p>This offers important advantages when a calibration laboratory must regularly work across different flow ranges.<\/p>\n<p>Instead of removing one molbloc and installing another, two different molbloc-L ranges can remain connected to the calibration platform.<\/p>\n<p>The operator can therefore switch between the available ranges with significantly less hardware reconfiguration.<\/p>\n<p>Dual configurations are available for Low Flow and Mid Flow applications.<\/p>\n<h2>Two molbloc-L Elements for Wider Range Coverage<\/h2>\n<p>The Dual molstic-L is particularly useful when two different molbloc-L sizes are combined.<\/p>\n<p>For example, one molbloc can be selected for low flows and another for higher flows.<\/p>\n<p>Together they can provide substantially broader flow coverage than a single molbloc.<\/p>\n<p>This modular concept is particularly valuable because the molbloc-L family covers gas flows from approximately:<\/p>\n<p><strong>1 sccm to 100 slm<\/strong><\/p>\n<p>depending on the selected flow element, gas and operating pressure.<\/p>\n<p>The molstic-L therefore provides the physical platform required to make efficient use of the modular molbloc concept.<\/p>\n<h2>Low Flow molstic-L<\/h2>\n<p>The <strong>Low Flow molstic-L<\/strong> is optimized for very low gas flow applications.<\/p>\n<p>Fluke uses a special high-stability pressure regulator and minimizes internal dead volume.<\/p>\n<p>This is important because pressure instability and unnecessary internal volume can have a significant influence when operating at very low gas flow rates.<\/p>\n<p>Low Flow molstic-L systems are required for effective use with:<\/p>\n<p><strong>2E2-L and lower molbloc-L elements<\/strong>.<\/p>\n<p>They can also be used with molbloc-L elements up to:<\/p>\n<p><strong>1E3-L<\/strong>.<\/p>\n<p>The Low Flow configuration also uses the finer <strong>0.5 micron filter<\/strong>.<\/p>\n<h2>Mid Flow molstic-L<\/h2>\n<p>The <strong>Mid Flow molstic-L<\/strong> covers a particularly broad selection of molbloc-L elements.<\/p>\n<p>Fluke specifies Mid Flow configurations for molblocs ranging from approximately:<\/p>\n<p><strong>2E2-L<\/strong><\/p>\n<p>through:<\/p>\n<p><strong>3E4-L<\/strong>.<\/p>\n<p>This makes the Mid Flow molstic-L a versatile solution for many common laboratory gas flow calibration applications.<\/p>\n<p>Single and Dual versions are available.<\/p>\n<h2>High Flow molstic-L<\/h2>\n<p>The <strong>High Flow molstic-L<\/strong> is designed specifically for Fluke Calibration&#8217;s largest molbloc-L.<\/p>\n<p>It is required for the:<\/p>\n<p><strong>1E5-L<\/strong><\/p>\n<p>molbloc.<\/p>\n<p>The 1E5-L provides nominal gas flow capability up to approximately:<\/p>\n<p><strong>100 slm<\/strong>.<\/p>\n<p>Fluke specifies that the High Flow molstic-L supports the 1E5-L only.<\/p>\n<p>The larger pneumatic configuration is necessary to handle the higher gas flow without introducing excessive unwanted pressure drop.<\/p>\n<h2>Low, Mid and High Flow Comparison<\/h2>\n<p>The three molstic-L configurations allow the mounting system to be matched to the molbloc-L being used.<\/p>\n<p><strong>Low Flow<\/strong><\/p>\n<p>Optimized for very low gas flows.<\/p>\n<p>Required for 2E2-L and smaller molblocs and usable up to 1E3-L.<\/p>\n<p>Uses a high-stability regulator, reduced dead volume and 0.5 micron filtration.<\/p>\n<p><strong>Mid Flow<\/strong><\/p>\n<p>Supports a broad range of molbloc-L elements from approximately 2E2-L through 3E4-L.<\/p>\n<p>Available in Single and Dual configurations.<\/p>\n<p><strong>High Flow<\/strong><\/p>\n<p>Designed specifically for the 1E5-L 100 slm molbloc.<\/p>\n<p>Available as a Single configuration.<\/p>\n<p>Selecting the correct molstic-L is therefore important for achieving optimum molbloc\/molbox system performance.<\/p>\n<h2>Compact Integrated Construction<\/h2>\n<p>The <strong>Fluke Calibration molstic-L<\/strong> integrates high-quality pneumatic components onto a dedicated mounting platform.<\/p>\n<p>This provides a more structured solution than assembling a calibration bench from individual regulators, filters, valves, tubing and mounting components.<\/p>\n<p>Advantages of the integrated design include:<\/p>\n<ul>\n<li>Defined component arrangement<\/li>\n<li>Reduced setup complexity<\/li>\n<li>Easier molbloc installation<\/li>\n<li>Improved reproducibility<\/li>\n<li>Organized pressure connections<\/li>\n<li>Simplified DUT connection<\/li>\n<li>Easier leak testing<\/li>\n<li>Compact laboratory installation<\/li>\n<\/ul>\n<p>This is particularly useful in professional calibration laboratories where the same flow setup is used repeatedly.<\/p>\n<h2>Dimensions<\/h2>\n<p>The dimensions depend on the selected molstic-L configuration.<\/p>\n<p>For example, Fluke specifies a main platform length of approximately:<\/p>\n<p><strong>584 mm<\/strong> for the Single Low Flow configuration.<\/p>\n<p>The Dual Mid Flow configuration has a main platform length of approximately:<\/p>\n<p><strong>690 mm<\/strong>.<\/p>\n<p>The Single High Flow configuration also has a main platform length of approximately:<\/p>\n<p><strong>690 mm<\/strong>.<\/p>\n<p>The complete dimensions vary according to the regulator, valve and connection configuration.<\/p>\n<h2>molstic-L with molbloc-L<\/h2>\n<p>The distinction between the <strong>Fluke Calibration molstic-L<\/strong> and molbloc-L is important.<\/p>\n<p>The:<\/p>\n<p><strong>molbloc-L<\/strong><\/p>\n<p>is the characterized laminar mass flow element.<\/p>\n<p>The:<\/p>\n<p><strong>molstic-L<\/strong><\/p>\n<p>is the mounting and pneumatic system.<\/p>\n<p>The molstic-L itself does not determine the reference flow.<\/p>\n<p>Instead, it creates the controlled mechanical and pneumatic environment in which the molbloc-L operates.<\/p>\n<h2>molstic-L with molbox2<\/h2>\n<p>A modern gas flow calibration setup can combine:<\/p>\n<p><strong>Fluke Calibration molstic-L + molbloc-L + molbox2<\/strong><\/p>\n<p>The individual functions are clearly separated.<\/p>\n<p>The <strong>molstic-L<\/strong> provides:<\/p>\n<ul>\n<li>Gas supply connection<\/li>\n<li>Filtration<\/li>\n<li>Pressure regulation<\/li>\n<li>Isolation<\/li>\n<li>Mechanical mounting<\/li>\n<li>DUT connection<\/li>\n<li>Optional flow adjustment<\/li>\n<\/ul>\n<p>The <strong>molbloc-L<\/strong> provides:<\/p>\n<ul>\n<li>Characterized laminar flow element<\/li>\n<li>Precision flow restriction<\/li>\n<li>Individual calibration characteristics<\/li>\n<li>Integrated temperature measurement<\/li>\n<\/ul>\n<p>The <strong>molbox2<\/strong> provides:<\/p>\n<ul>\n<li>Differential pressure measurement<\/li>\n<li>Absolute pressure measurement<\/li>\n<li>Temperature measurement<\/li>\n<li>Gas property calculations<\/li>\n<li>Reference mass flow calculation<\/li>\n<li>Flow indication<\/li>\n<li>Communication and automation capabilities<\/li>\n<\/ul>\n<p>Together, these components create a complete professional gas mass flow calibration system.<\/p>\n<h2>molstic-L vs. molstic-S<\/h2>\n<p>The <strong>Fluke Calibration molstic-L<\/strong> and molstic-S are both mounting platforms for the Fluke Calibration molbloc\/molbox system, but they are designed for different flow elements.<\/p>\n<p>The:<\/p>\n<p><strong>molstic-L<\/strong><\/p>\n<p>is designed for:<\/p>\n<p><strong>molbloc-L laminar flow elements<\/strong>.<\/p>\n<p>The:<\/p>\n<p><strong>molstic-S<\/strong><\/p>\n<p>is designed for:<\/p>\n<p><strong>molbloc-S sonic nozzle flow elements<\/strong>.<\/p>\n<p>Because the two flow technologies have different pressure, flow and connection requirements, Fluke provides dedicated molstic systems for each type.<\/p>\n<p>For a laboratory using both laminar and sonic nozzle flow standards, the corresponding molstic-L and molstic-S platforms provide a structured approach to building the complete flow calibration system.<\/p>\n<h2>Integration into Automated Flow Calibration Systems<\/h2>\n<p>The <strong>Fluke Calibration molstic-L<\/strong> can form part of a fully automated molbloc\/molbox calibration system.<\/p>\n<p>The reference flow is measured by the molbloc\/molbox system while appropriate control hardware manages the flow conditions.<\/p>\n<p>Depending on the configuration, automation can include:<\/p>\n<ul>\n<li>Flow point generation<\/li>\n<li>MFC control<\/li>\n<li>Reference flow measurement<\/li>\n<li>Pressure measurement<\/li>\n<li>Temperature measurement<\/li>\n<li>Stabilization<\/li>\n<li>Data acquisition<\/li>\n<li>Calibration sequence execution<\/li>\n<li>Result processing<\/li>\n<\/ul>\n<p>This allows the same basic molstic-L platform to be used in both manual and automated calibration environments.<\/p>\n<h2>COMPASS for Flow<\/h2>\n<p>A complete molbloc\/molbox system can be integrated with Fluke Calibration&#8217;s:<\/p>\n<p><strong>COMPASS for Flow<\/strong><\/p>\n<p>calibration software.<\/p>\n<p>The software supports automated gas flow calibration procedures and coordinates compatible Fluke Calibration flow hardware with the device under test.<\/p>\n<p>The molstic-L provides the physical and pneumatic platform while the molbox and software perform the measurement, control and automation functions.<\/p>\n<h2>Available molstic-L Models<\/h2>\n<p>Fluke Calibration currently lists several molstic-L configurations.<\/p>\n<p><strong>MSTIC-401316<\/strong><\/p>\n<p>molstic-L

platform for molbloc-L laminar mass flow elements.<\/p>\n<p>Rather than assembling a flow calibration system from individual filters, regulators, valves, tubing and mounting components, the molstic-L integrates the essential components into a compact system specifically designed to maximize molbloc\/molbox performance.<\/p>\n<p>An integrated filter protects the downstream components, while the adjustable pressure regulator establishes the required molbloc operating pressure and protects the molbox pressure transducers against accidental overpressure.<\/p>\n<p>A bellows shut-off valve simplifies configuration changes and system leak testing.<\/p>\n<p>Dedicated cradles provide stable molbloc mounting, while the downstream connection allows a mass flow controller, other device under test or optional precision metering valve to be installed directly into the system.<\/p>\n<p>Low Flow, Mid Flow and High Flow configurations ensure that the pneumatic system can be matched to the required molbloc-L range.<\/p>\n<p>Single and Dual versions provide additional flexibility, with Dual systems allowing two molbloc-L elements to remain installed simultaneously for faster switching between different flow ranges.<\/p>\n<p>Combined with a <strong>Fluke Calibration molbloc-L<\/strong> and <strong>molbox2 Flow Terminal<\/strong>, the molstic-L becomes an essential part of a modular,
