Model 241 and 240 Vortex Flow Meter (Rental)


The Sierra Vortex Meter 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 ability to sense all process conditions in a single location greatly improves measurement accuracy of this flowmeter and eliminates the costly requirement for additional line penetrations associated with traditional mass flow measurement systems.
The sophisticated on-board flow computer inside the steam vortex flow meter also incorporates AGA-8 algorithms for natural gas measurement to reduce billing and contract disputes. The multivariable meters’ smart electronics provide access to all measured variables and programming menus, and permit field-configuration directly from the flow meter control panel or workstation via RS485, MODBUS or HART protocols
