The Series PUB & PUF Portable Ultrasonic Flowmeter Kits utilize the transit-time difference for measuring flow rates in pipes non-invasively. They are compact and lightweight instruments incorporating the latest electronics and signal processing technologies, realizing high performance and easy operation. These devices are perfect for on-the-go flow monitoring, capable of 20 hours continuous operation with built-in, rechargeable battery. The PUB comes with a rugged carrying case with molded foam inserts while the PUF boasts an IP67 rated case to hold and protect all equipment conveniently. Their screens offer easy to read text with convenient backlight for visual comfort. The efficient layout of the function keys adds to these units’ easy to use programming. These series offer analog as well as a pulsed outputs.
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.
Calibration Option available under Accessories.
For the data logging version see Series PUF.
