Netherlands in Europe, because of the local policies, water recycling is required to decrease water resource waste. Groundwater extraction also leads to the deterioration of the local ecological environment, and the cost of collecting water from other places remains high, at the same time, it also does harm to environmental protection. Local government wants to make a rainwater collection system to save water resource. The collected rainwater would be used to municipal irrigation in order to realize full utilization of water resources.

1.The degree of rainwater pollution in different neighborhoods are different, including sediment, suspended matter, etc., and How to avoid the impact of the medium on sensor measurements.

2,In the whole collection system, real-time liquid level monitoring of each trough is required. The depth of the trough is between 80-100mm, how to select the liquid level sensor?

3. It is necessary to establish a visualization platform for the entire system to understand the precipitation situation in each region from a macro perspective in order to guide the work of the back-end water storage and treatment system.

Targeting customers project needs, we recommend customers using our GLTV7S capacitive liquid level sensor. we recommend that customers use our GLTV7S capacitive liquid level sensor. The product is suitable for small-scale liquid level monitoring, with small blind areas and high accuracy. It adopts an automatic calibration procedure, and changes in the medium do not affect the liquid level measurement of the product. Considering that the sensor measurement points are scattered and the signal collection cost is high, it is recommended that customers use a wireless acquisition module to directly upload the collected liquid level information to the customer's system management platform to achieve visual observation of liquid level data and back-end water storage. The system uses our input-type liquid level GLT500 for liquid level monitoring, and controls the liquid level of the reservoir based on real-time rainfall analysis; the collected water is treated and used for municipal irrigation. The system realizes full utilization of water resources and makes great contributions to environmental protection.
