The four wire ultrasonic level gauge is a liquid level measuring instrument that, with its advanced technology design and reliable performance, can be widely used in various industrial scenarios, providing users with accurate and stable liquid level measurement services.

Product Features

High quality circuit design

The circuit design of this liquid level gauge selects high-quality power modules from the power supply section, and all components are imported high stability and reliability devices, ensuring the performance and stability of the entire instrument. This high-quality circuit design enables it to replace similar imported instruments from abroad, providing users with a more cost-effective option.

Intelligent sound wave technology

The sound wave intelligent technology software of ALT-666 is a major highlight of this liquid level gauge. It can perform intelligent echo analysis without any debugging or other special steps, and has the functions of dynamic thinking and dynamic analysis. This advanced acoustic technology not only improves the accuracy of the instrument, but also enables it to resist various interference waves, with a liquid level accuracy of up to 0.3%, and can maintain stable and reliable measurement results in complex industrial environments.

Non contact measurement and low failure rate

As a non-contact instrument, the Hangzhou four wire ultrasonic level gauge does not come into direct contact with the liquid, greatly reducing the failure rate. At the same time, the instrument provides multiple installation methods, and users can calibrate the instrument through this manual, which is easy to operate and maintain.

Powerful protection function

All input and output lines of the instrument have lightning protection and short-circuit protection functions, ensuring safe and stable operation even in harsh industrial environments, effectively extending the service life of the instrument.
