What is hydrostatic level measurement?

Hydrostatic level transmitters use the measurement of pressure to work out the contents of a tank.  The measuring cell of a pressure transmitter can detect small increases or decreases in level by converting the pressure acted upon it from the changing amount of content into an electrical signal.  Electronics built into a housing with the sensor convert this signal so that it can be displayed locally or transmitted to remotely monitor or control the contents.

Hydrostatic Level Transmitters

Offering a range that includes side mounted pressure transmitters with chemical seals for aggressive fluids in storage tanks and top mounted submersible pressure transmitters for tanks, wells, shafts and bore holes


This technology particularly suits abrasive and aggressive applications or those in difficult to reach places where accuracy is essential to prevent potential spillages, monitor underground water levels or spot leaks in difficult to reach places.

  • Simple installation
  • Low maintenance costs
  • Suitable for aggressive liquids
  • Unaffected by foaming
  • Good for leak detection in tank walls

Train level measurement, gauges and indicators

To solve a specific problem with access and the lack of height between a fuel tank and the trains body, AMS have modified the head of our approved level sensors to allow fitting in confined spaces. This development also removed the need for the transmitter to be located in a separate box on the side of the tank and allowed the sensor to be wired directly to the indicators, saving significant additional costs in materials and wiring time.

Train level measurement and control

Advances in the way instrumentation can be powered due to processing capabilities at reduced power levels, combined with the ever-continuing miniaturisation of electronics capability, has created the opportunity for rail companies to consider more modern electronic/digital technology as an alternative to the traditional methods for level measurement.
