This document introduces the technical information of TI 397F/28/zh/04.07/(10.07) and the features of using it with the series of ultrasonic probes. The ultrasonic measurement instrument can be used for level measurement and flow measurement, with various applications and functions such as limit detection, pump control, and grid control. Its advantages include simple menu-guided operation, envelope curve display for quick and easy fault diagnosis, convenient operation, diagnostic and measurement point file compilation through the provided operating software. It also has features such as loop digital input and external temperature signal input.
The Prosonic S FMU90 is an ultrasonic measuring instrument designed for level and flow measurement in liquids, slurries, mud, dust and rough solid materials. It can be equipped with one or two ultrasonic probes (FDU series) and supports up to six relay outputs, multiple accumulators and counters, and optional external sensors.
This manual covers system design, measurement principle, input and output configuration, HART and PROFIBUS DP integration, wiring diagrams, external limit‑switch and temperature‑sensor connections, and safety warnings. It also includes application examples for level and flow measurement, as well as programming of linearisation curves and pump‑control functions. This manual is written in Chinese.
