| | Mar 13, 2014 — Dwyer Instruments, Inc., the preferred source for your complete range of practical and affordable instrumentation, is announcing the release of its new model UFM Compact Ultrasonic Flowmeter.
The Series UFM Ultrasonic Flowmeter is a compact, low cost clamp-on, ultrasonic flowmeter. It has a compact and lightweight design, featuring an easily installed, all in one clamp-on unit. This unit can measure velocity and flow in steel, copper, plastic pipes with outside diameters ranging from 0.98 to 4.62” (24.89 to 117.35 mm). The screen offers easy to read text with a convenient backlight for visual comfort. This series comes with a volume pulsed output and 4 to 20 mA flow rate output. This model is capable of displaying instantaneous and totalized flow for monitoring flow and batch quantity. Its compact, low cost, and easy installation make this an ideal product for monitoring and metering water flow in Building Automation Systems.
The model UFM operates via the transit-time difference with two sensors located in the guiderail that is placed on the exterior of the pipe, and each sensor 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.
