Liquid Measurement Systems (LMS) engineers and manufactures commercial and military grade Digital Fuel Quantity Indicators to exact specifications. We integrate the latest technologies in delivering digital devices that our customers know they can trust.

Liquid Measurement System (LMS) capacitance AC and DC fuel gauging probes use lightweight and durable carbon composite materials. In addition to being some of the lightest fuel probes in the industry, they are also virtually immune to corrosion, cracking, dents, and extreme field conditions. Our capacitance probes are inherently crash resistance by collapsing onto itself during hard impact landings to avoid tank penetration and fuel leaks. All electrical connections on the probe are bonded, and there is no friction or riveted electrical connections.

* Reduces development time * Works with a variety of fuel tank configurations * Streamlines mounting and installation

Liquid Measurement Systems (LMS) provides fuel gauging and interface controls for service, maintenance, and flight crew personnel, at the primary refuel point on the aircraft.

External Refuel Preselect Panels can display the quantity of fuel in each tank, calculate the total quantity of fuel onboard, allow service teams to pre-select desired fuel quantity, and display fault codes. LMS’ external refuel preselect panels are compact, lightweight, and rugged systems that can be adapted to a variety of platforms.

* Delivers Class III accuracy * Processes signals from up to 12 probes/sensors * Capacity for up to 8 different tank configurations * All in one signal conditioning unit
