Vortex flowmeter VortexMaster FSV450

VortexMaster FSV450 is the universal vortex meter for high-end flow applications. It uses a two-wire transmitter with leading-edge DSP technology with enhanced flow computer functionality. Signals from remote sensors like pressure, temperature, or density can be read by an integrated analog 4 … 20 mA interface and computed directly with the flow and temperature signals measured by the device itself. FSV450 is ideal for direct mass flow or standard flow of gasses and liquids or direct mass and energy flow on saturated and overheated steam.

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 an 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. VortexMaster FSV450 is available with multiple communication protocols, such as

4 to 20mA / HART 7,
Modbus TCP and Profinet via Ethernet -APL,
Modbus RTU, Profibus PA, and FOUNDATION Fieldbus.

Features

Versatile measurement – suitable for volumetric, mass, and energy flow of liquids, gases, and saturated or superheated steam.
2-wire transmitter with advanced digital signal processing (DSP) for stable and accurate measurement.
Integrated analog input (4–20 mA) for external sensors (e.g., pressure, temperature, or density) — allows direct mass and energy calculation without a separate flow computer.
