Clamp on flow meters

Clamp on flow meters,ultrasonic flow meter,flow meter,measuring instrument 1% of accuracy 4 flow totalizersTypes Portable TypeHandheld TypeFixed TypeMeasuring PrincipleWhen the ultrasonic beam is transmitting in the liquid,its transmit time is proportional to the liquid flow.Applicationfor continuously measuring the flow of most clear,single and pure liquid which do not have large consistence suspended matter or bubbles.LinearityBetter than 0.5%AccuracyBetter than 1.0%RepeatabilityBetter than 0.2%Velocity Range0±32m/sPipe MaterialsSteelstainless steelcast ironPVCcement pipe and other pipes whose materials are close .
