SANSEI innovations - automatic level control for pools, spas, containers, fountains, water tanks - with fill and empty function

Electronic level difference switch for automatic level monitoring of conductive liquids in pools, spas, containers, fountains and water tanks. With the slide switch on the front, the device can be used either for refilling or draining. The liquid level is automatically maintained between two water sensors (min. and max.). We recommend this device in combination with the 3/4 inch solenoid valve, but it can also be used to control a pump. As soon as the water level falls below the min. sensor, the solenoid valve opens and fills the container (e.g. pool) until the max. sensor is reached. This level control device is suitable for all storage tanks made of concrete, plastic or metal and is quick to install as all connections are pluggable. The device is largely trouble-free without float switches, which can often lead to failures due to corrosion or soiling.

Installationsbeispiel

Level control in a dedicated shaft with a specialised sensor and a brass solenoid valve. It can also be installed in the skimmer or the overflow basin.

Note: Conductive liquids

The water sensors work in all conductive liquids. Water does not always conduct equally well. The conductivity depends on the salts or ions dissolved in it. Water can therefore be more or less conductive. Sufficient conductivity is important for the water sensors to function properly. 

Tap water, salt water or contaminated water are highly conductive liquids. Osmosis water, distilled water or pure rainwater are poorly conductive liquids and may therefore be unsuitable for water sensors.

With rainwater in particular, the function of the water sensor can be variable, as the conductivity of rainwater is subject to strong fluctuations due to environmental influences.

If you want to use a water level switch for poorly conductive liquids, we recommend a mechanical float switch instead of a water sensor or the addition of some regenerating salt, which increases the conductivity but is not suitable for irrigation.
