Product Introduction

1.Introduction

The ultrasonic level meter integrates the advantages of various domestic and international level meters, solving the long-standing challenge that ultrasonic technology cannot be applied under high-temperature conditions. It adopts fully digital and humanized design concepts as a general-purpose level meter, featuring complete functions for level measurement & control, data transmission and man-machine interaction.

This product supports isolated 4–20mA, HART, and wireless data transmission via built-in GPRS, NB-IoT, LoRa, RF, GPS, Bluetooth, etc. Additional modules can be customized to realize other functions upon customer requirements.

2.Technical Features

This product features strong anti-interference performance, good linearity and high accuracy. It can meet most liquid level and solid level measurement requirements without contacting industrial media. It thoroughly eliminates drawbacks of traditional measuring methods such as pressure type, capacitance type and float type, including winding, blockage, leakage, medium corrosion and inconvenient maintenance. Therefore, it can be widely applied in various fields related to solid and liquid level measurement & control.
