Talking about the application description of liquid level meter in subway project

The subway is the lifeline of the city's underground life, which is especially important to ensure the normal operation of the subway.
In the subway station, there are many collection wells, sewage pools and other places. The water levels in these wells or pools need to be monitored in real time to avoid spillage, especially in seasons where rain is concentrated. A timely drain of this water requires a level controller. Several liquid level gauges commonly used today are: 1. float level controller; 2. input level gauge; 3. ultrasonic level gauge
In the early days, there were still a lot of float level controllers because they were simple and easy to install. It is widely used in pump valve control. But it also has shortcomings and a short life span. It usually needs to be replaced once every 5-6 months.
The input level gauge is now the most widely used level controller. Analog output for real-time monitoring of current levels. High precision, easy installation and reasonable price. From the beginning of the cable-input level gauge, to the current collector-type input level gauge. Improved the problem that the input level gauge is easily blocked by sludge. long lasting.
As an emerging liquid level controller, the ultrasonic level gauge was originally introduced from abroad. High price, accurate measurement, non-contact measurement. It has been welcomed by many users and has been chosen by many design institutes as the first choice. However, many on-site situations are more complicated, and it is embarrassing to choose an ultrasonic level gauge. The collecting well is too small and too shallow. The shortcomings of the blind spot of the ultrasonic level gauge are more troublesome. If the installation is not good, it is easy to see the liquid level entering the blind spot and then flooding the ultrasonic level gauge. Thanks to the efforts of the Chinese people, the performance of the domestic ultrasonic level gauge is also very good, which can completely replace imported products. And after-sales service is better, with the support of many users.
Now in the liquid level control, the float level control, the input level gauge and the ultrasonic level gauge are all commonly used, and the user will also use it according to the actual situation on site.
