Measure the liquid level in the level gauge without contact. Two types of non-explosion-proof and explosion-proof explosion proof are available.

In a non-contact from the outside of the tank, to measure the liquid level in the level gauge

  • Insert a dedicated float on the liquid level inside the gauge and measure from the outside.
  • Unlike conventional contact type, continuous signal output is possible.
  • The main body is made of SUS304, excellent in corrosion resistance, the length can be designed freely.
    ■ It can be used with simple initial setting (one touch push button).

The following two types are prepared by non-explosion-proof type and explosion-proof type.

  • FXL ⇒ non-explosion proof type
  • FXD ⇒ flameproof type

1. It is safe design with no damage or leakage of the gauge.

2. easy to see by the color of the display surface, has become a stain-resistant structure.

3. The visible range is taken long, weight is also very light liquid level gauge.

4. You have an excellent pressure-resistant and heat-corrosion-seismic and weather resistance.

5. offers optimal Explosion-proof in dangerous goods tank according to the Fire Defense Law.
