Level Indicator

The Smart Well indicator is equipment for water level measurement in boreholes, dug wells, and reservoirs. The level indicator can measure the level up to 100 metres with a 1 cm accuracy, depending on the probe used.


How a Level Indicator Works

The level indicator consists of a hydrostatic probe and a control unit. The unit displays the water column height above the probe based on the data achieved from it.

The measurement is influenced by the current atmospheric pressure; however, the measuring deflection caused by the change in the atmospheric pressure can differ by ±0.2 m from the actual level.

The level indicator is designed for a long-term installation; therefore, you are immediately informed of the state of the water.

Parts of Level Indicator

The core of the level indicator is a measuring unit for data assessment.

A probe made of stainless steel and materials harmless to health are an integral part.

The package includes all the materials necessary for the installation. SmartWell


Installation of Level Indicator

For boreholes, we recommend fastening the probe and cord to the pump pipe to ensure the accuracy of the measurement and also to prevent the pump or probe from getting damaged when being removed from the borehole.

For this purpose, the package includes a holder and tightening straps. Hanging the probe in a reservoir and well is possible only using the original probe cord.

The control unit may be placed thanks to its water resistance and the possibility to power it from a battery wherever it suits you.

Information on an easy-to-read



SW1 Unit

The SW1 unit is the core of the battery level indicator and is controlled by a microprocessor. An easy-to-read LED-backlit LCD displays the measured values.

A water-resistant button is placed on the bottom side of the unit. The power supply is secured by one 9V battery that has, thanks to the automatic Standby mode, a lifespan longer than two years.

A sturdy plastic box with dimensions 78 mm x 118 mm x 54 mm ensures the electronic parts stay protected from mechanical damage and water leakage.

SW2 Unit

The SW2 unit is the core of the online level indicator. Thanks to this unit, you can check the current level state under control from any corner of the world.

Graphs, information about the ambient temperature, and the possibility of implementation into a smart home are a matter of course.
Because it is easy to connect and start it without a single setup, the Smart Well is unrivalled.

A sturdy plastic box with dimensions 126 mm x 55 mm x 176 mm ensures the electronic parts stay protected from mechanical damage and water leakage.

A probe is an integral part of the level indicator, which measures the level of the water column above it. We recommend placing it at the same height as the pump protection sensor. If a pump does not have a sensor, it is recommended to place the probe approximately 1 m above the pump.

In our offer, you can find a wide range of probes from which you can find the one that fits your needs.

Extension Possibilities

Even though the cord of the S1 probe is 45 m, the S2 is 75 m, the S3 is 15 m, and S4 is 105 m, it might not be long enough for some customers because of the placement of the control unit.


The Level Indicator Operation

The level indicator operation is so easy that everyone can do it after a correct calibration and installation.

With the SW1 unit, just press one button to display all the information.

With the SW2 unit, simply open the website, where you can immediately see all the information, from the current state to the graphs.

Why Level Indicator

Investing in foundation of a well is not modest. When you have a well constructed, you want it to work perfectly for many years. If you treat it well, it will reward you with good water as well as long-term service.

One of the key factors is the supervision of the water level. Pumping too much water might damage the well and the pump irreversibly. Measuring the water level with a string is inappropriate and, in the case of boreholes, even impossible.

Every manipulation might contaminate the water. The graph shows the behaviour of an average borehole level based on the seasons.
