Mass flow rate, volumetric flow s. c. (standard condition), volumetric flow a. c. (actual condition), molecular weight, gas volume and mass, gas velocity, sound velocity
Detection of flare gas leaks, steam flow measurement, monitoring of gas losses, monitoring of steam injection in flare gas burning as well as process optimization are fields of use for this gas flowmeter FLOWSIC100-Flare-XT. It measures values such as gas velocity, gas volume, mass flow rate, molecular weight, volumetric flow and sound velocity. Additionally, it provides an intelligent device monitoring process and supports predictive maintenance - designed for current and future challenges.

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.
On the new factory calibration rig from Endress+Hauser, Wintershall Dea can now calibrate Promass F with hydrocarbons as legally mandated – a significantly cheaper option than on-site calibration.
