The Series UFB & UFC Ultrasonic Flowmeter Sets utilize the transit-time difference

for measuring ow rates in pipes. These units are permanent mount, where the converters can be mounted on a surface or pipe with a 4 to 20 mA and pulse output capabilities for pipe sizes from1/2 to 79˝ (13 to 2000 mm). The Series UFC offers the same features plus data logging capability.
