On-vehicle Volumetric Flow Detector

FP-4135

Considering temperature changes in the engine room and environmental testing, the flow detection section and signal processing section are separated.
It supports approximately 3 G of vibration and environmental temperatures from -30 °C to +100 °C, exhibiting excellent vibration resistance and environmental resistance.
Vibration test: 27.3 m/s ²
Temperature test: -30 °C to +100 °C

The miniaturization of the filter has achieved a space-saving of 70% compared to our model (compared to FP-2140H).
It comes standard with a super compact filter inside the detector, protecting the detector from impurities contained in the fuel. The filter is removable and can be maintained by the customer for each test.
A temperature sensor is also standard.
Temperature measurement: -30 °C to +100 °C
Temperature accuracy: Class A

By installing a vehicle joint (optional) on the upper part of the detection unit, it can be easily piped to the vehicle's fuel hose. This also reduces the risk of fuel leaks in the engine compartment.

 Wide range: flow range 0.1 to 200 L/h
Low pressure loss: adopting a magnetic encoder and reducing the weight of the detection part to lower pressure loss
Alcohol fuel compatible: using liquid contact parts with excellent chemical resistance 

A compact and vibration-resistant onboard fuel flow detector FP-4135 and a small and lightweight GPS speedometer LC-8300A will be installed on a motorcycle to measure the average speed, fuel consumption, and fuel efficiency every 10 meters from the start. Based on the results, the fuel efficiency performance of the vehicle will be evaluated.

When used in an engine bench on stage, it is possible to extend the maintenance period for filter cleaning by adding an external filter to the primary side of the flow meter. (The filter is subject to a separate estimate.)
