Vehicle-mounted positive displacement flow detector

FP-4135

The flow detection unit and signal processing unit are separated to take into account temperature changes in the engine compartment and environmental testing.
It can withstand vibrations of approximately 3 G and ambient temperatures from -30 °C to +100 °C, offering excellent vibration and environmental resistance.
Vibration test: 27.3 m/s²
Temperature test: -30 °C to +100 °C

By miniaturizing the filter, we have achieved a 70% reduction in space compared to our previous model (FP-2140H).
A miniature filter is standard equipment inside the detector to protect it from impurities in the fuel. The filter is removable and can be maintained by the customer after each test.
A temperature sensor is also included as standard equipment.
Temperature measurement: -30 °C to +100 °C
Temperature accuracy: A class

By attaching an optional vehicle fitting to the top of the detection unit, it can be easily connected to the vehicle's fuel hose. This also reduces the risk of fuel leaks in the engine compartment.

 Wide range: Flow rate range 0.1 to 200 L/h
Low pressure loss: By employing a magnetic encoder and reducing the weight of the detection unit, pressure loss is reduced.
Alcohol fuel compatible: Features wetted parts with excellent chemical resistance. 

A compact, vibration-resistant vehicle-mounted fuel flow detector (FP-4135) and a small, lightweight GPS speedometer (LC-8300A) are mounted on a motorcycle, and the average speed, fuel consumption, and fuel efficiency are measured every 10 meters from the start. Based on the results, the vehicle's fuel efficiency performance is evaluated.

1. When used on a bench-mounted engine test bench, etc., it is possible to extend the maintenance interval for filter cleaning by adding an external filter to the primary side of the flow meter. (Filters are quoted separately.)
