Fuel Flow Meter FQ-3100DP

Overview

The FQ-3100DP fuel flow measurement system offers a highly precise method of measuring various fuel types for engines of up to 700 kW. The unit has a unique measuring range due to the DP sensor, which allows for a highly accurate measurement, even at very low consumption rates. In addition, the data transmission rate of 100 Hz enables highly dynamic measurements. These features make the fuel flow measurement system perfectly suited for demanding research and development applications, including testing of small engines (incl. single-cylinder research engines) and exploring lowest fuel consumption.

Measurement Techniques

Delta Pressure Principle with Active Driven Internal Gear Pump

Within the internal gear pump a piston in a bypass regulates the pressure difference between fuel inlet and outlet of the gear pump. The volume flow causes the piston to start moving which breaks the light barrier. This activates the servomotor, which will start to regulate the internal gear pump until the pressure is equalized again. The volumetric flow will be calculated based on the rotation frequency and the geometry of the gears.
