Product Details
AMETEK Sensors & Fluid Management Systems (SFMS) designs and manufactures fluid densitometers that measure fuel density for aircraft fuel-mass calculations. The design uses piezoelectric materials and is engineered for accurate operation across changing fuel, temperature, viscosity, pressure, and flow conditions.
- Supports fuel-mass calculation from volumetric inputs
- Accurate across fuel, temperature, and viscosity extremes
- Suitable for static and flowing-fuel applications
- Intrinsically safe design for fuel-tank operation
AMETEK SFMS applies aerospace engineering, manufacturing, calibration, and environmental test experience to tailor each solution to the required installation, interface, and performance needs.
Benefits
- High Accuracy
