Escort ALS


It is used for monitoring the level of liquid in storage containers in various industries.

The water level sensor is a modified fuel level sensor with the ability to measure the level of conductive liquids, including weak solutions of alkalis and acids (the concentration is not more than 10% of the total volume of the liquid).

Escort ALS water level sensor:

  • combines the most common types of output signals: digital RS-485, frequency and analog;
  • the measuring part of the sensor can be easily adapted to any depth of the container;
  • the water level sensor is configured, connected and installed similarly to the fuel sensor Escort;
  • perfectly interacts with monitoring systems of any manufacturers;
  • it is possible to measure the level of a conductive liquid in various containers.
