Level Transmitters

We design products that are built to last, making them maintainable and repairable, reducing the cost of ownership.  We do not create waste by forcing replacement through obsolescence.


Radar (GWR/TDR)

Reed Relay or Float Operated

Hydrostatic Level

Level Switches

Manufactured in the UK for over 50 years our float switches are complimented by a range of electronic level switches with specification options to meet applications and budgets.


Float Switches

Capacitance Probes

Vibrating Switches

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.
