Fuel tank level indicator/ magnetic level indicator with magnetostrictive level transmitter

The cage is flanged to the tank & the level is indicated on a Strip which consists of magnetic bi-colour rollers. The floats are available in various metallurgies like SS316, Titanium, PVDF, Polypropylene and PVC.
  • Used for high temp and pr applications or if glass parts cannot be used for safety reasons.
  • Applications in Chemicals, Pharmaceutical, petrochemical, refineries, oil and fuel tanks etc.
  • Available in side andtop mounting versions
  • Capsule Indicator in glass tube or magnetic bi-color rollers
  • SS 304, SS 316, PTFE, PP, PVC & PVDF Float & Cage Material
  • Max. C.C. Distance : 6000 mm, greater lengths on request.
  • Flanged connection drilled ot ASA 150# or other on demand
  • Pr 20 Kg/cm2 for SS & 3 Kg/cm2 for PP, PVC & PVDF, Higher Pr rating on demand
  • Temp 450oC for SS, 80oC for PVDF, 60oC for PVC, 50oC (Max) for PP
  • Specific Gravity : Min 0.5
  • AI/SS etched scale in cm
  • +/- 5 mm accuracy
Principle of Operation
These models consists of Red or Black/white magnetic rollers equipped with small rod magnets which are rotated one after another at an angle of 180º by the magnetic field of the permanent magnet put inside the float. The rollers change from white to red on rising level and red to white on falling level. Plastic rollers are suitable for liquid temperature upto 100ºC & Alluminium rollers for temperature upto 250ºC and ceramic rollers for temperature upto 450ºC.
The level in a tank or agitating machine is permanently indicated as a Red or Black column even in the case of power fallure.
In addition, Level Sensing elements can be fixed directly to the float cage, so that-simultaneous, contact less sensing is measured electrically. Electronic Level indicator with set point can be connected with the sensor to have reading in remote. Single or double set point relays can also be provided in the electronic indicator for control purposes.
Magnetic level indicator is for on site level indication, use float as measurement unit, the magnet drive turned column showing the level without energy. It can work from low temperature to high temperature, from vacuum to high pressure, high viscosity, corrosion and so on. It measure the level safely and reliability. Under various environments to measure the liquid, the whole process of measurement without blind spots, display eye-catching, intuitive readings, measuring range.

Products matching upper and lower limit switch output, remote alarm can be realized, limit control.
