UAV On-Vehicle and Test Stand Fuel Measurement

Test stand and on-vehicle fuel flow measurement for unmanned aircraft is now possible. 

Fuel consumption and performance testing of unmanned aircraft continues to grow as longer flight times are desired.

Max Precision Flow Meters accurately measure from idle speed to full power fuel consumption for engines on unmanned aircraft.


With a weight less than 1 lb (0.45 kg), Max Precision Flow Meters now offers our highest performance, lowest flow rate meter in a smaller lightweight package for greater aerospace adaptability:

  • P001LA
    • K-Factor:  12,000 pulses/cc
    • Flow Rate:  0.005 – 200 cc/min

With an anodized aluminum housing that has been streamlined to remove all non-essential weight, the P001LA can be added to your flight performance testing payload to verify real flight direct fuel consumption.  All of the standard P001 measurement performance criteria apply. Changes are seen to the pressure rating which is now 250 psi (17 bar) and the weight which is less than half at 1 lb (0.45 kg).


  • Standardize lab tests and flight data with the same meter.
  • Increase data resolution, especially at low flows
  • Low weight, compact package for on vehicle use

Max Flow Meters are not sensitive to changes in flow profile, fluid density or viscosity.  With their high resolution and low flow measurement accuracy Max Flow Meters are the leading choice for both dynamometer and flight testing.  With a resolution of 12,000 pulses/cc, the heaviest part of the P001LA meter is the data stream.
