Fuel Management Systems

Indicator Conditioners

The PC900 series of Indicators/Conditioners incorporate digital circuitry to condition, temperature compensate, and accumulate the output from an engine-mounted turbine flowmeter. They provide a traditional analog display of fuel flowrate in user specified units. Additionally, an auxiliary analog output is available to provide a convenient interface to a Flight Management System.

Features:

• Interfaces with newer flight management systems
• Established product history
