Endress + Hauser have announced the launch of the Prosonic Flow 92F, a state-of-the-art addition to their already cutting-edge range of ultrasonic flowmeters, and the world's first 2-wire loop powered inline ultrasonic flowmeter. The 92F offers a dynamic combination of a 2 wire loop powered transmitter and a multi-beam ultrasonic inline sensor. This enables easy electrical and mechanical installation, with minimal space usage and high accuracy performance.

The new flowmeter extends the application range of electromagnetic flowmeters and is ideal for both process and utility applications, especially in the chemical industry. It's also suitable for use with non conductive and conductive liquids.

The Prosonic Flow 92F transmitter is based on an industry proven design and is available in three output versions including 4 to 20 mA HART, 4 to 20 mA HART with additional status/pulse output and Profibus PA.

Device Type Management (DTM) software and Field Device Tool (FDT) technology support total system integration and the transmitter requires virtually no programming during the initial setup. Only the actual flow range has to be defined. Software independent data management is made possible via a HISTOROM T-Dat function where transmitter setup and sensor calibration data can be stored as a backup.

The Prosonic Flow F sensor is a multi-beam sensor that consists of a stainless steel sensor body, flanged process connections and 2, 3 or 4 pairs of ultrasonic sensors. The sensor pairs are located in two arrays on each side of the sensor body at an angle symmetrical around the sensor body axis. The ultrasonic sensors are welded into the sensor body removing the requirement for additional process gaskets.

The practical and efficient configuration of the ultrasonic sensors ensures the optimal scanning of flow velocity distribution in the measuring section of the sensor. This in turn reduces the requirement for upstream straight pipe to less than five times the pipe diameter.      

The Prosonic Flow 92F is at the forefront of flowmeter technology. It offers high accuracy (better than 0.5% optional 0.3%) and enables cost effective non invasive flow measurement, with no mechanical interaction with the flow. This makes it practically maintenance free.
