Level Sensor

The remaining fuel in the fuel tank is detected using a float floating on the liquid level.
These liquid level sensors have been developed for applications for motorcycles, automobiles and industrial equipment, and are
compatible with high reliability and low cost, based on the results of their use in automobiles worldwide.

Application Examples
Fuel Level Sensor for Motorcycles and Automobiles
Sliding Level Sensor
Sliding Level Sensor
Features

We have continued production for more than 40 years and have a track record of mass production of more than hundreds of millions of units. (Cars, motorcycles, agricultural machinery, construction machinery, ships, etc.)
We have a lineup of level sensors for various fuels (ethanol-containing fuels, sulfur-containing fuels, etc.) and the environment.

Features TYPE name
Thin type / for automobiles FU-11
Small type / for motorcycles FU-12
Sulfur-containing fuel / for automobiles FU-14
For ethanol-containing fuel SSF
Operating principle

Due to the fluctuation of the liquid level, the resistance value fluctuates as the float moves up and down.
This resistance value change is output to the fuel meter.

Hall IC Level Sensor
Hall IC Level Sensor
Features

【NCF】
[Application Example]Fuel Level Sensor for Automobiles

This is an in-vehicle sensor that enables liquid level detection for a variety of fuels. Uses a linear output Hall IC to select the analog type or digital type voltage output characteristic.

  • Compatible with ethanol and methanol 0-100% fuel.
  • It has the same fuel pump mounting structure as our mass-produced FU-12 type.
  • It is possible to measure the liquid level of water and conductive liquids.
  • Since it does not have a contact sliding part, the sliding resistance is small, it can be used for a small float compared to the sliding type, and it does not take up space in the tank.
  • High resolution: about 0.1 °
Operating principle

Due to the fluctuation of the liquid level, the voltage value fluctuates as the float moves up and down. This voltage change is output to the fuel meter. The magnet that works with the arm attached to the float rotates around the Hall IC, which changes the magnetic flux and the voltage output from the IC.

Features

  • Compact
  • Long life
  • No need for adjustment after installation.
  • Mounting can be adjusted by attaching flanges and stays.
  • Multiple sensors can detect multiple points.
Operating principle

A leed switch is inserted inside the stem, and when the float goes up and down in response to the floatingness of the liquid level, the leed switch is operated by the magnetic force of the magnet built into the float and becomes ON.
When the float is separated, the magnetic field is excluded, the elasticity of the leed fragment opens the contact, and becomes OFF.

Product Lineup
FU-11

【LG1:1 wire type】
[Application Example]Low fuel warning

Because the sensor body is used as part of the wiring available liquids are insulators such as gasoline, light oil, and kerosene.

FU-12

【LG1:2 wire type】
[Application Example]Drain pan full warning

Since the wiring is insulated from the sensor body, it can be used not only in the insulator, but also in the conductive liquid such as water.
