Vortex Flow Meters

The ABB FSV450 VortexMaster takes Vortex technology to the next level – ensuring a truly Smart, intelligent flowmeter – whether for Liquid, Steam or Gas measurement.

Designed as a universal vortex meter for high end flow applications, the FSV450 uses a two-wire transmitter with leading edge DSP-Technology with enhanced flow computer functionality. Signals from remote sensors like pressure, temperature, density or gas content can be computed directly with the signals from internal flow and temperature. Ideal for direct mass flow or standard flow of gases and liquids or direct mass and energy flow on saturated and super-heated steam.

Of the VortexMaster family, the FSV450 is the advanced version with additional analogue input for mass or energy flow measurement. Available with integral or remote transmitter with up to 30m (98 ft.) cable length.

The ABB Vortex Flow Meters are Renewable Heat Incentive (RHI) compliant.

Using the optional inputs, standalone flow computers are no longer needed in many applications.
