OPTISONIC 6300 Ultrasonic Clamp-On Flowmeter From KROHNE

OPTISONIC 3400, Ultrasonic Gas Flowmeter, KROHNEUltrasonic clamp-on flowmeter

The OPTISONIC 6300 stands for continuity and long term reliability. Flow measurement can be done anywhere and start-up is immediate.

The  OPTISONIC 6300 clamp-on flowmeter for liquids with its robust industrial construction and regreasing concept provides a revolutionary solution for easy handling. It can be fitted on the outside of piping to measure the flow rate of liquids.

The clamp-on flowmeter is a combination of one up to two OPTISONIC 6000 clamp-on sensor(s) and one UFC 300 ultrasonic signal converter. The overall functionality of the clamp-on flowmeter is the continuous measurement of actual volume flow, mass flow, flow speed, velocity of sound, gain, SNR and diagnosis value.
