Magnetic Float Indicator – MLG28

 

isolvBased on a single float and magnetic flaps or float indicator. The measuring tube that carries a float is installed like an external chamber to the side of a tank.

The magnet inside the float actuates the magnetic flaps or float indicator according to change in liquid level in the measuring tube.

The float or column of yellow colour flaps indicates the liquid level in the tank which corresponds to the liquid level in the measuring tube.

  • Different wetted part materials are available. For example stainless Steel, PTFE and PVC.
  • Rugged construction for the roughest industrial applications. These indicators perform in high temperature, high pressure, and many other applications requiring robust and high-quality design.
  • Little or no materials required and less risk of leakage than a sight glass
  • Add-on switches for Alarms and level control
  • Add-on 4-20mA transmitter suitable for temperature up to 200°C with special heat insulated cover on the measuring tube.
  • Level gauge with 4-20mA transmitter suitable for temperature up to 200°C with special heat insulation cover on the measuring tube.
  • Level measurement for low and medium height vessel or tank.
  • Measurement unaffected by presence of mechanical agitator or color of the fluid.
  • Can be used for interface level measurement. For example oil/water and foam/liquid.
