Vortex flowmeter VortexMaster FSV450

Universal version of vortex flowmeters with enhanced flow computer functionality for gases, liquid and steam



VortexMaster FSV430, FSV450

Data Sheet



VortexMaster flowmeters are used for accurate measurement of the flow of gas, liquid and steam over a wide temperature range. Vortex meters are ideal for measuring low viscose liquids, demineralized water and direct steam mass flow, and they are ideal for cost-effective, integral temperature measurement.

VortexMaster FSV450 is the advanced version with additional analog input for mass or energy flow measurement, available with integral or remote transmitter with up to 30 m (98 ft.) cable length. Because of the optional inputs, discrete flow computers are no longer needed in many applications.

Standard features:

HMI for easy meter set up
Analog 4 … 20 mA input
Integrated RTD for temperature compensation and saturated steam mass flow calculation
Digital outputs for pulses, frequency, and alarm signalization

Optionally available:

Remote transmitter with up to 30 m (98 ft.) cable length
Stainless steel transmitter housings
