Precision Metering of Fuel Consumption and Fluid Conditioning

Measure Fuel Flow for Autotest

With over 40 years of experience developing flow meters to measure fuel usage and other liquids, Sierra brings tremendous expertise and passion to fuel metering for the autotest industry. Sierra has a complete range of digital and electronic flow measurement and conditioning solutions for fuel and other liquids and gasses associated with engine and vehicle testing.

The FuelTrak gravimetric and combined gravimetric and transient fuel measuring systems are the product of choice for fuel flow measurement. With a field proven installed base built up for over a decade, FuelTrak is a compact high precision instrument for measuring specific fuel consumption of diesel and petrol / gasoline engines, fuel additives and resultant effects, and emission certification work. Sierra offers a range of fuel temperature conditioning and settable fuel pressure delivery modules for steady-state and transient testing.

Sierra also offers solutions for fuel and engine temperature control. The Sierra temperature control assembly is designed to provide temperature control of engine coolant, engine oil and turbo/intercooler (or other cooling circuits) in engine test applications, from a single bed water feed and return. The Fuel Pressure Regulation Unit offers precise control of fuel delivery pressure which includes:

  • Regulates supply pressure to engine
  • Range of units to provide stable pressure control 0.5 to 8bar
  • Delivery pressure and temperature logged
  • Suitable for gasoline & diesel fuel supplies
