The Perfect Ultra-Pure Water Ultrasonic Flowmeter

MetraFlow Non-Invasive PFA Ultrasonic Flow Sensor:

The Metraflow through-flow, ultrasonic flowmeter uses Titan’s patented transit time ultrasonic flow sensor technology to accurately measure liquid travelling through a PFA flow tube. The compact integrated electronic, display and sensor package offers superior performance in a single assembly. Computer and operational connections are separate, permitting setting and interface monitoring during normal operation. The units, time base, set points and analogue and digital outputs can all be set through the USB connector and meter interface software. Other parameters such as minimum flow cut-off, computer based data logging, display/output filtration and a negative flow flag can also be configured through this port.
