Float type level meters
- Pressure resistant and explosion-proof float type level sensor
This meter inherits the high functionality of the FXL series
-
Can measure liquid levels stably in an explosive atmosphere. This level meter is pressure-resistance and explosion-proof type, and has inherited the high functionality of the FXL series.
Respond to changes in the electrical characteristic of the material to be measured. Products that conform to the pressure-resistant explosion-proof standard (Exd II BT4).

Features, keys
- Can measure a wide range of materials
Not affected by electrical characteristic changes of the materials to be measured. It is not affected by temperature, pressure, or gas in the tank. - Safe design that endures harsh tank conditions
Can be used in various conditions including water-proof housings (protection class IP65), detection section can withstand a pressure of 1 MPa and heat resistant to 100 degrees. - Simple measurement settings
Simple initial settings (press buttons) for measurement. A small non-sensing area makes measurements possible over a wide range. - Many functions for safety measurement as standard
A delay setting function and watch dog function come as standard.
Usages, use examples
- Can measure liquid level in an explosive atmosphere.
- Works across a wide range of liquids, (and can even measure after the liquid type is changed, or the electrical properties of the liquid change)
- Harsh environments, extreme temperatures or pressures, and positions not easy to maintain or check.
