Series PUF Portable Ultrasonic Flowmeter Kit

Portable, Non-Invasive and Data Logging Capability

The Series PUF Portable Ultrasonic Flowmeter Kit utilizes the transit-timedifference for measuring flow rates in pipes non-invasively. It is a compact and lightweightinstrument incorporating the latest electronics and signal processing technologies, realizinghigh performance and easy operation. This device is capable of 20 hours continuousoperation with its built-in battery. The PUF comes with an IP67 rated carrying case withmolded foam inserts to hold and protect all equipment against dust and water. The screenoffers easy to read text with a convenient backlight for visual comfort. The efficient layoutof the function keys add to this unit's easy to use programming. The unit comes with RS232and USB connections to allow for easy connection to any personal computer or printer.

PRINCIPLES OF OPERATION
Two sensors are placed on the exterior of the pipe, and each transmits an ultrasonicpulse through the pipe and fluid to the other. The velocity of the liquid flowing throughthe pipes causes the pulse to accelerate or decelerate. The difference in the transittimes of the two pulses is used to calculate the flow rate. The use of transit timeallows the flowmeter to be unaffected by pressure or temperature changes.

Calibration Option available under Accessories.
