Krohne offers the Optisonic 7300 Biogas ultrasonic flowmeter, designed to measure dry and wet biogas with variable composition.
The flowmeter provides functions such as calculation of standard volume, methane content measurement and diagnostics features. There are no moving parts or pressure loss.
The device overcomes the limitations of the ultrasonic principle in biogas applications due to high damping of the acoustic signals by carbon dioxide and high water content in the biogas. Optisonic 7300 Biogas features a maintenance-free, full-bore flow sensor without any moving parts.
Because the hydrogen sulfide (H2S) in biogas is corrosive when dissolved in water, the measuring tube is made of stainless steel 1.4404/316L, and the transducers are made of NACE-approved grade 29 titanium for maximum corrosion resistance. www.us.krohne.com
