Water level sensor Liquid level sensor analog 0-5v/4-20mA/rs485 for farms

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.

Today, farms are large and manual irrigation can take a lot of time and be less efficient, while labor costs are high.

Automatic irrigation technology can reduce labor costs by 50% instead of manual irrigation. Automatic irrigation eliminates the need for irrigation ditches and borders in the field, making better use of the arable land than surface irrigation and improving land use, typically increasing the cultivated area by 7-10%. In addition, automatic irrigation will reduce the damage to the soil, which will help to increase the yield.

In order to achieve better control of farm irrigation and save more water resources, we need to design an effective remote controller for automatic farm irrigation.

The application of level sensors in the farm based growth intelligence automatic irrigation scheme.

The required sensors and the network are arranged on the farm, and the sensors are used to detect the plant soil and climate data.

In agricultural irrigation systems, the main role of the level sensor is to act as a water level control. The level sensor is usually located somewhere on the top and against the lower part of the tank. The level sensor automatically detects the depth of the water layer and transmits the collected data to the intelligent irrigation control system in real time through a wireless transmission device.

After the system diagnoses, the decision command issued is transmitted to the irrigation control device in the field, after which the water in the tank is automatically filled into the rice field. When the water level drops to that point, the output of the level sensor changes, which triggers the alarm system in the irrigation system and cuts off the power to the working circuit, saving irrigation water and improving water utilization.
