Vortex flow measuring system
Reliable flow measurement of gas, steam and liquids

The transmitter housings are available either intrinsically safe (Ex I) or explosion-proof (Ex d) for hazardous areas, and as compact or remote versions. Both versions of the two-wire transmitter can output volume flow and mass flow.

Features:
Distinguishing Features:
Digital filtering flow meter head
Battery power flow meter head
Self-developed, self-designed configuration without mold charges (including housing and body)
