Application Area Rainwater Cistern

Reliable measurement of the rainwater cistern's fill level

Precise Control for Your Rainwater Cistern

The Senvolon level meter is ideal for rainwater cisterns, garden tanks, and underground water storage. The sensor measures the fill level precisely, without contact, and reliably – regardless of whether rainwater, service water, or other liquids are in the tank. With MIN/MAX monitoring, you always know when the cistern is almost full or nearly empty. This prevents overflows, protects pumps from dry running, and keeps track of your water supply.

Your Benefits at a Glance

Simple Smart Home Integration (MQTT)

The sensor can be easily integrated into Home Assistant and other smart home systems to control automations.

Precise measurement – non-contact, maintenance-free

The level meter functions completely contact-free. Nothing comes into contact with the water, which is why:

  • no maintenance is required
  • no contamination occurs
  • no mechanical parts wear out

The sensor reliably measures the distance from the tank surface to the liquid using distance measurement – accurately and without interference.

Ideal for garden irrigation and domestic water systems

A rainwater cistern is often used for:

  • automatic irrigation systems
  • domestic water systems
  • garden pumps
  • raised beds or lawn irrigation

With the level indicator, you can ensure that enough water is always available. At the same time, you can optimize your irrigation without constantly having to open or check the tank.

Check fill levels at any time via smartphone

The Senvolon level meter can be integrated into multiple systems via MQTT, accessed via the internal Wi-Fi network, or remotely via remote.senvolon.de.

You receive:

  • Real-time readings
  • Access via smartphone or PC
  • Push notifications for MIN/MAX alarms

This way, you'll always know how much rainwater you have available, even when you're on the go.

Sustainable Use of Rainwater

With the Senvolon level indicator, you can use rainwater more efficiently:

  • less drinking water consumption
  • better irrigation planning
  • optimal use of your rainwater storage tanks

This way, you contribute to sustainable water use – especially important in hot summers or with rising water prices.
