Carrying Case

The Series PUF Portable Ultrasonic Flowmeter Kit utilizes the transit-time difference for measuring flow rates in pipes non-invasively. It is a compact and lightweight instrument incorporating the latest electronics and signal processing technologies, realizing high performance and easy operation. This device is capable of 20 hours continuous operation with its built-in battery. The PUF comes with an IP67 rated carrying case with molded foam inserts to hold and protect all equipment against dust and water. The screen offers easy to read text with a convenient backlight for visual comfort. The efficient layout of the function keys add to this unit's easy to use programming. The unit comes with RS232 and 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 ultrasonic pulse through the pipe and fluid to the other. The velocity of the liquid flowing through the pipes causes the pulse to accelerate or decelerate. The difference in the transit times of the two pulses is used to calculate the flow rate. The use of transit time allows the flowmeter to be unaffected by pressure or temperature changes.

Applications
