Explosion – proof level meter. Corresponds to a wide range of measured objects, and also supports changes in electrical properties.

Float type level gauge of explosion-proof structure inherits as it is a high-function of FXL

  • It is possible to measure the level of the liquid level stably even in an environment of explosive atmosphere.
  • It is a flameproof explosion-proof level meter that inherited the abundant functions of the FXL series.
  • It also supports changes in electrical properties of the object to be measured.
      ■ It is a product of pressure-resistant explosion-proof standard (Exd II BT 4).
    ■ It can be used with simple initial setting (one touch push button).
    ■ The dead zone can be greatly reduced, and it is possible to measure with a wide range of sensors.
We also have a special type for measuring the liquid level inside the glass gauge attached to a glass gauge.

1. corresponds to the wide range of the object to be measured
does not affect the electrical properties change of the object to be measured. It is not affected by temperature inside the tank, pressure, gas components.

2. safe design withstand the harsh tank conditions
waterproof housing (protection class IP65), the detection part of the pressure-resistant 1Mpa, corresponding to various use conditions, such as heat-resistant 100 ℃.

3. simple configuration can be used in
it can be measured with a simple initial setup (one-touch push-button). The undetectable part can be greatly reduced, and it can be measured in a wide range of degrees of freedom.

4. Equipped with each function for stable measurement
standard equipment such as a delay setting function and the watchdog function.
