ABB VortexMaster FSV430 Vortex Flowmeter
Overview
The ABB VortexMaster FSV430 is a vortex flowmeter for flow measurement of liquids, gases and vapors in pipes from DN 15 to DN 300 (1/2 to 16 in). It measures flow by detecting the frequency of vortices shed by a bluff body in the flow stream, providing a measurement with no moving parts that requires virtually no maintenance. Measuring accuracy is better than +/-0.65% of measured value for liquids and +/-0.9% for gases and vapors under reference conditions, with repeatability of +/-0.2% for DN 15 to 150 and +/-0.25% from DN 200 upward.
Engineering and Design
The FSV430 provides a 4-20 mA output with HART 7 communication, powered from 12 to 42 V DC with less than 1 W consumption. Damping is adjustable from 0 to 100 s, and a low-flow cut-off between 0 and 20% suppresses false readings at zero flow. In the event of an alarm, the current output can be set to 21-23 mA per NAMUR NE43. The device supports a programmable analog input (16-30 V DC) for connection of external pressure or temperature transmitters for mass flow and energy flow compensation, and it is SIL-qualified with an overall safety accuracy of +/-4% of measuring range.
The FSV430 is offered in wafer and flanged versions with DIN flanges PN 10-40 and ASME Class 150/300, and handles standard medium temperatures from -55 to 280 C (-67 to 536 F) with high-temperature options for steam service. Electronics are rated IP66/IP67 and NEMA 4X, with approvals including ATEX, IECEx, cFMus and NEPSI for hazardous areas. Options include an integral RTD for temperature-compensated mass flow, an oxygen service (degreased) configuration, energy flow mode and increased EMC protection, and devices are available with HART or Modbus communication with remote transmitter mounting up to 30 m (98 ft) of signal cable.
