Low power submersible level transmitter for liquid media.

For continuous level measurement of liquids CPK Automotive offers a level sensor. It is designed for the measurement,
recording, visualization and transmission of water levels at remote locations via the Internet. Level profiles of lakes, rivers or groundwater measuring points can be created and analyzed.

The proven hydrostatic pressure measurement enables reliable monitoring of the water level independent of water properties and tank geometry.

The level sensor is characterized by high measured value resolution and accuracy. It is extremely robust and durable and, thanks to very low power consumption, provides reliable measured values over several years.

A Longlife battery is integrated in the level housing, ensuring maintenance-free operation for several years.

The measured values with date and time are transmitted to a cloud at an interval that can be set by the user. The continuous data transmission takes place via NBIoT. The data can be conveniently retrieved online at any time. If limit values are exceeded, the alarm management informs the user via SMS or e-mail.
