Measure instantaneous and cumulative fuel flow rates during on-stage and in-vehicle fuel economy tests.

Volumetric flow refers to the volume of fluid flowing per unit time.
By installing the Volumetric Flow Detector FP series in the flow path and combining it with the digital flow meter FM-3100 or DF-2200, volumetric flow measurement can be easily performed.
Since the volume of fluid expands and contracts due to temperature changes, temperature management during measurement is important.

Principle of Measurement

Four pistons arranged radially in the flow detection section repeat reciprocating motion due to the liquid flowing from the inlet to the outlet. At this time, the movement of the pistons is converted into rotational motion by a crankshaft and transmitted to the magnetically coupled rotational detection section. The rotary encoder in the rotational detection section generates pulse signals corresponding to the amount of movement of the pistons.

Case Studies

The Importance of Temperature Management in Flow Measurement

Temperature changes in the piping flow path affect flow measurement.
Here, we will intentionally vary the fluid temperature and introduce its impact on flow measurement.

When the fuel is cooled in heat exchanger ①, the volumetric flow rate measured by FP-4135 initially increases due to liquid contraction caused by cooling. Subsequently, as the T2 temperature stabilizes, the volumetric flow rate measured by FP-4135 stabilizes but decreases. This is due to the increased density of the cooled liquid (making it harder to flow) and the cooling and contraction of pipes and fittings in the flow path, which increases the pressure loss.

Changes in fuel temperature affect the results of volumetric flow measurements. When measuring volumetric flow, it is important to use temperature control devices to keep the fluid temperature constant and to insulate the pipes to block the influence of external temperature changes.

Our High-Precision Fuel Flow Measurement System features a piping configuration that suppresses temperature changes and ensures reliable, high-precision flow measurement.

test conditions

  • Keep the fuel flowing at a constant flow rate.

  • Initially, no cooling water is flowed through heat exchanger ①.

  • At the 10-second mark of the time series graph, a sudden flow of cooling water at 15 °C is introduced to heat exchanger 1.
