Dwyer Instruments' PUB and PUF Portable Ultrasonic Flowmeter Kits measure flow rates non-invasively
Dwyer Instruments' Series PUB and PUF Portable Ultrasonic Flowmeter Kits use the transit-time difference for measuring flow rates in pipes non-invasively. Each of the devices is capable of 20 hours continuous operation with a built-in battery, which requires 6.5 hours to recharge. Both the PUB and PUF have an IP54 rating for the units and transducers and come with an IP67-rated carrying case with molded foam inserts to hold and protect all equipment against dust and water. The layout of the function keys adds to these units' functionality. Each unit comes with a 4 to 20mA connection to allow connections as well as a pulsed output. The PUF unit has data logging capabilities that can be transferred via RS232 and USB connections to any personal computer or printer.
