A new flowmeter for biogas applications
This company has introduced the new biogas-handling version of its Optisonic 7300 ultrasonic flowmeter (photo), which is suitable for methane-gas applications in wastewater-treatment facilities. The two-beam flowmeter is now Class 1, Div. 1 approved, and provides repeatable measurements over a wide bi-directional flow range of± 30 m/s with 1% accuracy. The standard model uses titanium for optimized signal processing in challenging applications. Stainless-steel transducers are available on request. The Optisonic 7300 biogas flowmeter features a maintenance-free full-bore flow sensor with no moving parts and robust construction with no exposed cables. The converter features a variety of measurement diagnostics and available methane content output. Booth 916 — Krohne Inc., Peabody, Mass.
