Endress+Hauser Ultrasonic Flow Meters

Endress+Hauser’s ultrasonic flowmeter portfolio offers versatile and economical solutions for measuring the flow of liquids and gases across a wide range of industries, including water & wastewater, chemical processing, oil & gas, life sciences, food & beverage, and power & energy. Ultrasonic technology enables non-invasive or inline flow measurement that is independent of electrical conductivity and suitable for large pipe sizes (up to DN 4000).

Key products include portable and clamp-on devices like Prosonic Flow 93T, ideal for temporary monitoring and test measurements with battery-powered operation; Prosonic Flow P 500, a high-performance clamp-on meter for conductive and non-conductive liquids with flexible installation; Prosonic Flow 91W and W 400, robust transit-time clamp-on meters for water and process liquids; and specialist solutions like Prosonic Flow B 200 for wet biogas and digester gas measurement.

Ultrasonic gas flowmeters such as FLOWSIC600, FLOWSIC600-XT, FLOWSIC600 DRU-S, FLOWSIC500, and FLOWSIC100 expand the portfolio into accurate gas measurement, from custody transfer and high-performance applications to emission monitoring and robust upstream gas measurement tasks. These devices feature advanced diagnostics, wide measuring ranges, and options for dry or wet gas conditions.

Together, the ultrasonic flowmeter range supports flexible, maintenance-free flow measurement with multiple installation options (clamp-on, inline, or insertion) and broad application coverage—from temporary testing and process water to high-accuracy gas flow and biogas analysis
