Series UFB Ultrasonic Flowmeter Set
The Series UFB Ultrasonic Flowmeter Set utilizes the transit-time difference formeasuring flow rates in pipes non-invasively. This is the permanent model, allowing theuser to mount the converter on a surface or pipe. The easy-to-use compact and lightweightdesign is intended for mechanical devices using ideally homogeneous liquids that contain noair pockets. The Series UFB comes with a sturdy IP65 rating, protecting it from dust anddirect water contact. The Series UFB has 4 to 20 mA and pulse output capabilities.
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.
