UF3300 NEW Ultraflo, Fixed Clamp-on Flow and Process Measurement Meter

Brand: Micronics Ltd

Our fixed flow meter solution for closed pipe applications is ultrasonic, clamp-on and non-invasive, This means considerable savings from no cutting pipes or downtime interruption to process whilst the meters are being installed and low operation costs ie; no in-line blockages and dry maintenance.

The ULTRAFLO UF3300 brings simplicity to the non-invasive measurement of liquid flow and process measurement.

It offers the user quick and accurate flow measurement. And with its easy to follow menu and simple set up results can be achieved in quick time!
