1. Overview
Thank you sincerely for choosing our ultrasonic level gauge!
Ultrasonic level gaugeContaining multiple technologies, it has the characteristics of safety, cleanliness, high precision, long service life, stability and reliability, and easy installation and maintenance. It is suitable for various fields such as acid, alkali, salt, anti-corrosion, and high temperature.
Ultrasonic level gaugeIt can be connected to display meters or various DCS systems through 4-20mA or RS485 (Modbus protocol or other customized protocol), providing real-time liquid level data for industrial automation operation.
This instrument has the following characteristics:
The circuit design selects high-quality power modules from the power supply section, and selects imported high stability and reliability components, which can replace imported instruments of the same type.
The sound wave intelligent technology software can perform intelligent echo analysis without any debugging or other special steps. This technology has the functions of dynamic thinking and dynamic analysis.
Our company possesses sound wave intelligent technology,The accuracy has been greatly improved, with a liquid level accuracy of 0.3% and the ability to resist various interference waves.
This instrument is a non-contact instrument that does not come into direct contact with liquids, resulting in a low failure rate. The instrument provides multiple installation methods, and users can calibrate the instrument through this manual.
All input and output lines of the instrument have lightning protection and short-circuit protection functions.

3. Principles for Instrument Installation
1) The distance from the probe head to the lowest liquid level should be less than the range of the selected instrument.
2) The distance from the probe head to the highest liquid level should be greater than the blind spot of the selected instrument.
3) The emitting surface of the probe should be parallel to the liquid surface.
4) The installation position of the probe should try to avoid positions where the liquid level fluctuates violently, such as the inlet and outlet directly below.
5) If the pool wall or tank wall is not smooth, the installation position of the instrument should be at least 0.3m away from the pool wall or tank wall.
6) If the distance from the probe head to the highest liquid level is less than the blind spot of the selected instrument, an extension tube with a diameter greater than 120mm and a length of 0.35m to 0.50m should be installed vertically, with a smooth inner wall, and the opening on the tank should be larger than the inner diameter of the extension tube. Alternatively, connect the pipe to the bottom of the tank, with a diameter greater than 80mm, and leave a hole at the bottom of the pipe to maintain the liquid level in the extended pipe at the same height as the tank.
