Application area: rainwater tank

Reliably measure the fill level in the rainwater tank

Precise control for your rainwater tank

The Senvolon level sensor is ideal for rainwater tanks, garden tanks, or underground water reservoirs. The sensor measures the fill level in a precise, contactless, and reliable way, regardless of whether the tank contains rainwater, process water, or other liquids. With MIN/MAX monitoring, you always know when the tank is almost full or nearly empty. This way, you avoid overflow, protect pumps from dry running, and keep an eye on your water supply.

Your benefits at a glance

Contactless, precise measurement

The fill level is measured exactly and completely contactless, so neither the sensor nor the technology comes into contact with the water.

Reliable MIN/MAX monitoring

The sensor automatically warns you as soon as critical levels are reached, whether overflow or an imminent dry run.

Easy smart home integration (MQTT)

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

Precise measurement: no contact, no maintenance

The level sensor works completely contactless. Nothing comes into contact with the water, which means:

  • 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, precisely and without interference.

Ideal for garden irrigation and domestic water systems

A rainwater tank is often used for:

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

With the level sensor, you can ensure enough water is available at all times. At the same time, you can optimize your irrigation without constantly having to open or check the tank.

Check the fill level via smartphone at any time

The Senvolon level sensor can be integrated into multiple systems via MQTT, and retrieved via the internal Wi-Fi network or via remote access at remote.senvolon.de.

You get:

  • real-time readings
  • access via smartphone or PC
  • push notifications for MIN/MAX alerts

This way, you know how much rainwater you still have available, even on the go.

Sustainable use of rainwater

With the Senvolon level sensor, you use rainwater more efficiently:

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

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