Product
LMS is a leading manufacturer of high-performance Digital Fuel Quantity Indicators (DFQIs) for commercial and military aircraft. Our DFQIs are designed to integrate seamlessly with our Signal Conditioning Units (SCUs), providing pilots with precise, real-time fuel level data to enhance safety and decision-making in the cockpit.
A critical component of the refuel control panel, our DFQIs play a key role in the overall fuel management system by ensuring accurate data gathering and transmission from the fuel tanks to the cockpit. By focusing on digital technology, LMS delivers superior readability, customization, and accuracy, setting a new standard in fuel management.
Bright, digital displays offer superior readability compared to traditional needle gauges, especially in low-light conditions.
Advanced electronics deliver precise fuel level measurements, ensuring safe and efficient flight operations.
Available in compact 2-inch square or round configurations, our DFQIs fit seamlessly into existing instrument panels.
Configure your DFQIs to display up to six individual fuel tanks, along with vital information like total fuel quantity and error codes.
Built to withstand the demanding environment of the cockpit, our DFQIs are EMI and environmentally tested per industry standards (MIL-STD-461/810 or DO-160).
Compatible with both analog voltage and ARINC 429 digital inputs, our DFQIs integrate effortlessly with existing fuel management systems.
