Water level sensor For Agricultural Aquaculture analog 0-5v/4-20mA/rs485

Water level sensor Product introduction：

The water level sensor uses a high-precision, high-stability diffusion silicon pressure-sensitive chip, and through a high-reliability amplifying circuit, converts the water level signal of the liquid to be measured into signals such as current and voltage, which are available for users to choose. 

This product can be widely used in industrial field water level measurement and control, soil, paddy field,hydrological measurement and monitoring, ships and navigation systems.

Water level sensor Instrument maintenance：

1. Requirements for water use of the water level device: water that represents the local natural water body (river, river, lake) should be used as much as possible. In areas where it is difficult to obtain natural water, drinking water (well water, tap water) can also be used; the water in the device To keep clean, there is no floating objects on the water surface, no small insects and suspended dirt in the water, no moss, no significant change in water color; generally change the water once a month. The water level bucket should be cleaned when the water level gauge is changed, and the temperature of the replaced water should be close to the temperature of the original water;

2. Stop observations in areas with a long freezing period in winter, and use a small water level gauge to observe the water level on the ice surface throughout the freezing period. Drain the water in the large water level gauge to avoid freezing;

3. Before and after the flood season (for long-term stable frozen areas, before starting to use and after stopping use), check the leakage of the water level device once a year; if any problems are found, they should be dealt with;

4. Regularly check the installation of the water level gauge. If it is found that the height is inaccurate or not level, it should be corrected in time;

5. The water surface in the water ring should be close to the water surface in the water level bucket.
