7 March 2007 -- The new Endress+Hauser 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. 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 in compliance with ATEX. 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 located in arrays directly opposite each other.
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 inline flow measurement.
The measurement requires no mechanical interaction with the flow, making it virtually maintenance-free and without additional pressure drop.
The transmitter is easy to set up, so only the actual flow range must be defined - a real time-saving bonus!.
Compatibility has been thought about too - Prosonic Flow 92F is available with 4-20mA, HART (additional status/pulse output optional), Profibus PA and Foundation Fieldbus, facilitating simple integration into existing systems.
