Vortex Flowmeter

Application：
It is used to measure the cubage and quality flow of the liquid, gas and steam in the closed industry pipe.

Features：
■ Intelligent compact design, can display instantaneous flowrate, total cumulate flow and meter factors;
■ Low-power double power supple design, adopt to E2PROM technic, inside parameter preservation permanently;
■Autoregulation to zero, eliminate zero offset;
■ Battery Low voltage alarm（≤2.7V），to remind customer to change battery;
■ Easy operation, have multi output singal interface.
■ Detecting probe adopt to optimum assembled structure and special technical encapsulation, excellent anti-vibration performance,
     temperature up to 380℃;
■ Piezoelectricity component enchase in the body of probe, no stuff inside, Stable performance;
■Measure range: 10:1;15:1;
■ Upper/ lower limit alarm and low flow cutoff function;
■ Detecting component keep clear of medium, no moving parts, low pressure .
