3/4-4" Ultrasonic heat meter with pulse output and Modbus® communications.

Series UBT Clamp-On Ultrasonic Thermal Energy Meter

NEMA 4 Enclosure with Integral Mounting Bracket

The Series UBT Clamp-On Ultrasonic Thermal Energy Meter is an economicalclamp-on ultrasonic heat meter. It is an ultrasonic alternative to the traditional inlinethermal energy meters. The series uses temperature sensors for energy measurementand ultrasonic waves with time differentials for flow measurement.

Product Applications
