The U1000 HM is an ultrasonic clamp-on thermal, heat/energy meter that uses ultrasound to measure flow rate and PT100 temperature sensors to measure flow and return temperatures. The U1000 HM displays energy rate and totalized energy with pulse output and Modbus communication, so it can be used as a standalone meter or as an integral part of an aM&T or BEM’s system. Simple to install – clamp-on to the pipe, set the pipe diameter and connect the power, no specialist skills or tools required and Modbus compatible.
