With Optisonic 7300 Krohne is completing its portfolio of gas meters. The 2-beam ultrasonic gas flowmeter provides excellent long term measurement stability and repeatability. It delivers high performance over a wide flow range. It measures bi-directional from ±30 m/s (± 90 ft/s) with an accuracy of 1 % of the measuring range. Optisonic 7300 can be calibrated either dry or by using air or natural gas. As standard, it uses titanium transducers which are better focused, equalising process fluctuations and avoiding acoustic feedback; stainless steel transducers are available on request.
