Sierra Innova Mass 241 Insertion Vortex Meter

 
Sierra Vortex Flow meter

General Description

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. 

The 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.

All SIERRA Vortex meters are usable for gas or liquid media
