The new Endress+Hauser Prosonic Flow 92F is the world's first 2-wire loop powered inline ultrasonic flowmeter. It is another state of the art ultrasonic flowmeters within the Prosonic Flow product range. The new model 92F is a new winning combination consisting of a 2 wire loop powered transmitter and multi-beam ultrasonic inline sensor. A combination offering easy electrical and mechanical installation with minimal space requirement and high accuracy

The new flowmeter is suitable for service in compact process plants in the chemical industry. It is applicable to electrical non conductive liquids as well as conductive liquids. It is a natural extension of the application range of electromagnetic flowmeters for both process as well as utility applications. The application range includes solvent and hydrocarbon derivatives. 

The Prosonic Flow 92 transmitter is based on a successful transmitter already used within the company. The transmitter is available in three output versions:

> 4 to 20 mA HART

> 4 to 20 mA HART with additional status/pulse  
   output

> Profibus PA                                      

The system integration is supported through a Device Type Management (DTM) program and Field Device Tool (FDT) technology. The Transmitter requires virtually no programming during the initial setup. Only the actual flow range has to be defined. The HISTOROM T-Dat placed in the front of the transmitter offers software independent data management where the transmitter setup and the sensor calibration data can be stored as a backup.

The Prosonic Flow F sensor is a multi-beam sensor consisting 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.
