The Flow-X flow computer provides gas volume conversion, event logging, parameter logging, and reports using state-of-the-art technology. Identical modules are combined in different housings, offering a multi-stream version Flow-X/P for 1 - 4 measuring distances with a local touch screen, or the version Flow-X/S for smaller installations with one measuring distance. It is the ideal partner for custody transfer gas metering solutions in installations with FLOWSIC600 ultrasonic gas flowmeters.

Setting up and monitoring equipment at an ammonia plant presents significant challenges. Engie Energía uses advanced technological solutions, like remote communication devices in hazardous areas.
Schluchseewerk AG wanted to record and optimize the efficiency of its turbines at the pumped storage plant in Wehr. Endress+Hauser offers the optimum solution with its ultrasonic clamp-on flowmeter.
GPsol, together with Endress+Hauser, developed a system that individually measures each component of extraction wells and provides as much information as possible about the current flow.
