Ritec partnerJerguson Magnicator FlashProof magnetic level indicator
Magnicator with a larger 3" Sch 40 chamber and two internal float guides for boiling liquids and flashing vapours, 12" to 240" centres, SG down to 0.36, up to 1919 psig (132 barg) at 100 °F, -325 °F to 1000 °F.
Boiling liquids and flashing vapours cause trouble in standard magnetic level indicators. When the liquid in the chamber is much warmer than in the vessel, for example cold product on a hot summer day, vapour builds up under the float and it can sink or give a false reading.
The FlashProof Magnicator uses a larger 3” Sch 40 chamber with two internal guide rods. Entrained gas can escape past the float without disturbing it, and the guides hold the float against the indicator side of the chamber so the magnetic field stays close to the flags, transmitter or switches. The result is an accurate level reading on light hydrocarbons, liquefied gases and refrigerants.
Below 32 °F a non-frost extension and cryogenic insulation are recommended so ice does not hide the indicator.
Selection data we need
Medium and its specific gravity at operating conditions, operating and design pressure and temperature, ambient conditions, centre-to-centre distance and connections, materials, indicator type, insulation or frost extension, and switches or transmitter.
Applications
- Ethane, ethylene, propane, propylene, butane, LPG and LNG
- Liquid nitrogen, carbon dioxide, anhydrous ammonia and refrigerants
- Light end hydrocarbons and atmospheric distillation towers
- Cold liquid in the vessel with warm ambient heating the chamber
