Plant control

Under the condition that rain water plants should be reliable in service and user-friendly, the installation

of an automatic plant control is recommended. It should always regulate the protection of the pump

before unlubricated operation/air and refeeding of drinking water with lack of rain water.

To recommend optical level control is additional.

 Requirements of a plant control:

 

1. High switching firmness, permanent and maintenance-poor function, small quiescent currents.

2. Work of the water-contacting parts within the weak current range, short operating paths.

3. Optimal use of the storage volume; small, but sufficient sedimentation volume during attitude of the unlubricated operation protection.

4. Minimum drinking water supply meeting demand (½ daily requirement)

5. Use of noncorrosive, pollution free materials (also with fastening parts)

6. Small energy consumption
