InnovaMass® 241 VTP (Multivariable Vortex Meter)
Insertion Multivariable Mass Flow Meter
A unique insertion multivariable vortex mass flow meter, the Model 241 is a true workhorse in large pipe applications, high pressure applications and numerous geothermal steam applications.
Our Model 241 provides a direct reading of mass flow rate from a single entry point in the process line and provides analog and digital outputs of five process variables: mass flow rate, volumetric flow rate, temperature, pressure, and fluid density. The unique insertion design has probe lengths from 2-inches up to 72-inches and can measure air up to 67000 scfm and saturated steam up to 330,000 pounds/hour. In addition, the instrument is available in a high-pressure version capable of mass flow measurement of gases up to 5000 psig. The Model 241 has emerged recently as the proven instrument of choice in geothermal steam applications across the globe. The ability to sense all process conditions in a single location greatly improves measurement accuracy and eliminates the costly requirement for additional line penetrations associated with traditional mass flow measurement systems.
Our digital communications solutions offer engineers and systems integrators, full industrial system integration and networking capability with Sierra's vortex flow meters. Digital communications solutions include: BACnet, HART, Modbus RTU, and Profibus DP. This flexibility of communication features offers turnkey solutions for integration of Sierra's vortex flow meters into any industrial automation system or application.

The sophisticated on-board flow computer also incorporates AGA-8 algorithms for natural gas measurement to reducing billing and contract disputes. Smart electronics provide access to all measured variables and programming menus, and permit field-configuration directly from the control panel or workstation via RS485, Modbus, HART, BACnet protocols.
Product accuracy is ± 1.0% of rate over a 30:1 range for liquids and +/-2.0% of rate over a 30:1 range for gas and steam. Volumetric accuracy is ± 1.2% of rate over a 30:1 range for liquids and +/-1.5% of rate over a 30:1 range for gas and steam.The Model 241 is hazardous area approved for FM, CSA, ATEX and CE.
