Vortex Flow Meter

Multivariable measurement as insertion probe.
Optionally with installation and removal device.

Vortex Flow Meter
Insertion Version Typ: DVE

Our vortex flowmeter provides accurate and reliable flow measurement. In addition to the high-precision velocity sensor, the flowmeter includes a precision temperature sensor and a pressure transmitter. Thus it is possible to measure volumetric flow, mass flow, temperature, pressure, density and energy consumption with one device. The multivariable principle reduces complexity and cost compared to installing multiple individual devices to obtain the same process measurements.

The installation concept as an immersion probe allows easy installation via a weld-in socket. An additional advantage here is that with the use of the optional installation and removal device, the measuring device can be removed without interrupting the process.
