Accurate Flow Monitoring, Simplified Wirelessly
Overview:
Accutech TM10 Wireless Turbine Meter Totaliser Field Unit
The Accutech™ TM10 wireless turbine meter field unit measures the volumetric flow rate of liquids or gases by detecting the frequency of pulses generated with a standard turbine meter (not included) and applying a user-configured proportional “K” factor. A 22-point correction curve can be used for custom calibration of the turbine meter. The unit provides two principal outputs: flow rate and totalised flow measurements.
