The OPTISONIC 7300 Biogas is an ultrasonic flowmeter for low pressure biogas, landfill and sewage gas applications. The flowmeter is ideally suited to measure biogas with a high CO2 content as well as small amounts of other media like H2S, nitrogen, hydrocarbons or condensation water. Its corrosion resistant titanium transducers provide a strong ultrasonic signal into the gas. The signal processing of the meter allows a better detection of small, strongly dampened acoustic signals.
