Flow detector with pressure loss compensation function
NEW
FP-2130S/FP-2140S
The FP-2130S and FP-2140S positive displacement flow detectors, when used in combination with FM/DF series digital flow meters, are positive displacement flow detectors that accurately measure the flow rate of fuels such as gasoline, diesel, and kerosene. When a flow detector is installed in a flow path (pipe), pressure loss of the detector can change the fuel supply state to the engine, potentially affecting engine combustion. pressure loss-compensated flow detectors reduce pressure loss of the detector itself, minimizing the impact on the operating environment.
This function compensates for pressure loss by servo-driving a motor coupled to a rotary encoder, ensuring that the free piston is always in the neutral position (zero pressure difference).
The position of the free piston is constantly detected by an eddy current sensor.
