Intrusive Ultrasonic Meter

Manufacturer: Faure Herman

Model: FH83 Neo

The Ultrasonic Meter manufactured by Faure Herman, model FH83NEO, is designed to measure all types of liquids, whether conductive or non-conductive.

Thanks to its variety of digital and analog inputs / outputs, the FH83NEO easily interfaces with any process management system.

The ability to provide 1, 2 or 3 beams allows the Model FH83NEO meter to be tailored to application-specific precision and flow and profile requirements.

Modern and Innovative Transducers

Derived from the latest technological innovations, the transducers used in the ultrasonic model FH83NEO ensure excellent measurement reliability.

Measurement stability over time is a key feature for applications such as leak detection or monitoring of industrial manufacturing processes. The possibility of replacing transducers with the line in operation, makes it possible to maintain the continuity of production or transfer of the product by pipeline, facilitating maintenance on site.

Communication between the FHView software and the ultrasonic model: FH83NEO is carried out through the MODBUS protocol through an RS-485 serial port.
