Endress+Hauser Prosonic Flow 92F Ultrasonic Flowmeter

Overview

The Endress+Hauser Prosonic Flow 92F is an inline ultrasonic flowmeter engineered for the chemical and petrochemical industries, pairing a rugged full-bore sensor with the loop-powered Prosonic Flow 92 transmitter for straightforward system integration. Its ultrasonic measuring principle delivers accurate volume flow data without introducing any obstruction into the process stream, eliminating the pressure loss and wear associated with mechanical flow elements.

As the official authorized partner and exclusive regional representative for Endress+Hauser, Seven Star LLC proudly supplies the Endress+Hauser Prosonic Flow 92F to process plants and industrial facilities across the Sultanate of Oman and the wider GCC, backed by genuine factory calibration, full documentation, and local technical support.

Measurement Principle

The Endress+Hauser Prosonic Flow 92F measures flow using the transit-time ultrasonic principle. A pair of ultrasonic transducers mounted on the inline sensor body send acoustic signals diagonally across the pipe, both with and against the direction of flow; the difference in transit time between the two signals is directly proportional to the average fluid velocity, from which volumetric flow is calculated.

Because the transit-time method is independent of pressure, density, temperature, conductivity, and viscosity, the Prosonic Flow 92F holds its accuracy across changing process conditions. The full-bore inline design has no moving parts and no flow obstruction, resulting in zero additional pressure loss, no wear-related maintenance, and no risk of media contamination from mechanical wear debris.

Engineering Design of the Endress+Hauser Prosonic Flow 92F

The sensor body is available in nominal diameters from DN 25 to DN 300 (1 inch to 12 inch), rated to PN 40 / ASME Class 300 / JIS 20K, with wetted materials of A351-CF3M or 1.4404/TP316/TP316L for DN 25 to DN 100, and A106 Grade B for DN 150 to DN 300, covering a medium temperature range of –40°C to +200°C.

The Prosonic Flow 92 transmitter is loop-powered for simplified two-wire installation and features a backlit local display for on-site readouts and configuration. The flanged, full-bore inline design allows straightforward retrofitting into existing pipework without the alignment sensitivity of clamp-on sensor mounting.

Key Features

The Endress+Hauser Prosonic Flow 92F is engineered for accurate, low-maintenance flow measurement, and the Endress+Hauser Prosonic Flow 92F is a proven choice across chemical and petrochemical process lines:

• Delivers volume flow accuracy of ±0.5% standard, improving to ±0.3% with the calibration option, for flow velocities of 0.5 to 10 m/s.
• Introduces zero additional pressure loss thanks to its full-bore, obstruction-free flow path.
• Remains accurate independent of process pressure, density, temperature, conductivity, and viscosity.
• Covers nominal diameters from DN 25 to DN 300 (1 inch to 12 inch) for a wide range of line sizes.
• Handles medium temperatures from –40°C to +200°C for typical chemical process duty.
• Has no moving parts, eliminating wear-related maintenance and contamination risk.
• Is loop-powered for simplified two-wire wiring and installation.
• Is rated to PN 40 / ASME Class 300 / JIS 20K for standard and higher-pressure process lines.

Industrial Applications

The Endress+Hauser Prosonic Flow 92F is specified across chemical and petrochemical process units, refineries, and general industrial process lines where an obstruction-free, low-maintenance flow measurement is required for corrosive, clean, or particulate-free liquids. Its accuracy independent of fluid properties also makes it well suited to blending and transfer applications where feedstock composition varies.
