Ultrasonic gas flowmeter

The OPTISONIC 7300 offers an ultrasonic measurement system dedicated for process gas flow applications. The OPTISONIC 7300 does not have the limitations that are usually associated with traditional gas flow meters like periodical recalibrations, maintenance, pressure loss and a limited flow range.

The OPTISONIC 7300 combines the advantages of ultrasonic measurement in a way that it is efficient, reliable and easy to use.
