Go ultrasonic with the new Prosonic Flow 92F

Endress+Hauser's new Prosonic Flow 92F is the world's first 2-wire loop powered inline ultrasonic flowmeter, offering easy electrical and mechanical installation with minimal space requirement and high accuracy.

Prosonic Flow 92F is ideal for use in compact process plants in the chemical industry. It is suitable for both conductive and non-conductive liquids and its 2-wire loop powered configuration makes it intrinsically safe to ATEX certification.

The Prosonic Flow 92 transmitter is available in three output versions:


	PROFIBUS PA
	4…20mA HART
	4…20mA HART with additional status/pulse output

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 multi-beam sensor allows a fully comprehensive scan of the flow whilst also offering greater installation flexibility as it can be used with short installation lengths. What's more, the ultrasonic sensors are welded into the sensor body, eliminating the need for additional process gaskets.

Prosonic Flow 92F offers high accuracy (better than 0.5%, optional 0.3%) for cost-effective non-invasive flow measurement. The measurement requires no mechanical interaction with the flow making it virtually maintenance-free and without additional pressure drop.

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 must 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 data management can also be performed remotely by means of the FieldCare configuration tool or locally by Fieldtool and the service interface FXA291 via the Common Data Interface (CDI). The CDI is also used by the verification tool FieldCheck. What's more, the diagnostic codes are organised according to the VDE/NAMUR guidelines. These were recently implemented as a part of a common Endress+Hauser standard for field devices offering device independent diagnostic messages.
