The U1000MKII-FM is an ultrasonic permanent/fixed clamp-on flow metering solution for measuring flow rate and total flow with a volume pulse output and optional Modbus or 4-20mA flow proportional output, which can be used as a stand alone meter or as part of an integral management system.
Simple to install – connect power enter the pipe inside diameter and material, adjust the sensors and clamp-on the pipe – no specialist skills or tools required! A cost effective alternative to traditional in-line meter installation, plus dry servicing, providing minimum downtime and maximum availability! Compact, rugged and reliable, the U1000MKII-FM has been designed to provide sustained performance in industrial environments.
Now available with the option of the original pipe-mounted or seperate wallmounted keypad and display plus extended pipe range and a heat/energy meter version.
