Series PUB Portable Ultrasonic Flowmeter Kit

PUB-20 Series PUB Portable Ultrasonic Flowmeter Kit, Type B, 2" to 40" (50.7 to 1016 mm) Pipe Diameter Range.Portable and Non-InvasiveIncludesConverter Set of Transducers Transducer Holders Set Transducer Cables [6.56 ft (2 m)] 4 to 20 mA Communication Cables 12 VDC Power Supply Ultrasonic Coupling Grease Set of Chains Ruled Guide Rail Test Block Carrying CaseThe Series PUB 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 PUB comes with an rugged carrying case with molded foam inserts to hold and protect all equipment conveniently. 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 a 4 to 20 mA connection to allow connections for a pulsed output.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.ApplicationsTreated Water River Water Sea Water Potable Water Demineralized Water Glycol/water mix Hydraulic System Diesel Oil.
