The Series UFB 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 4-20 mA and pulse output capabilities for
pipe sizes from 1/2 to 79˝ (13 to 2000 mm).
BENEFITS/FEATURES
• Non-invasive pipe measurement
• Easy-to-use compact and lightweight design, intended for homogeneous liquids that
contain no air
• Simple installation with all necessary components included such as converter,
sensor, cables and mounting accessories
• Sturdy IP65 rating, protecting it from dust and direct water contact
