Automatic Tank Gauges

Advanced Telemetrics manufactures the most accurate, robust and reliable multi-function automatic tank gauges on the market today. Our digital tank gauge has been proven in a wide range of severe environment, remote industrial applications. Commonly referred to as automatic tank gauge, float measuring device, magnetostrictive level transmitter, liquid level sensor or level measurement devices these mechanisms are capable of measuring different liquid levels in a container to an accuracy of 0.10 inch. Starting with an elegant core design our tank float can be configured as a single, dual or triple float measurement system. The tank gauges are available in wired or wireless configurations; our hard wired tank gauges are Class I, Division 1 rated and UL listed. Reliability is backed by our exclusive four year limited warranty, which is assured through the use of all solid state electronic components that directly measure actual fluid levels.
