Vortex flowmeter PS-UPVFX
PS-UPVFXVortex flowmeter for accurate measurement of steam, gas and liquids across a wide temperature range with a piezoelectric sensor and built-in temperature and pressure compensation.
Description
PS-UPVFX is a vortex flowmeter designed for accurate measurement of steam, gas and liquid flow in industrial environments. It uses the Kármán vortex street effect: a bluff body in the flow generates vortices at a frequency proportional to velocity.
The piezoelectric sensor delivers stable operation across a media temperature range of −20 to +420 °C. Integrated temperature and pressure compensation enables real-time mass-flow calculation — essential for steam and gas metering.
PS-UPVFX requires no routine maintenance, maintains long-term stability, and is ready for integration with SCADA systems via standard 4–20 mA and RS-485 (Modbus RTU) interfaces.
