Overview
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.
Optionally available:
- Smart HMI with backlight and Bluetooth functionality for easy meter setup (Ethernet-APL device only)
- Remote transmitter with up to 30m (98 ft.) cable length
- Stainless steel transmitter housings
- SIL 2
