Float & Board Level Indicator


Float & Board Level Indicator

Model No. : MI - 08


The Float & Board Level Indicators are designed for an accurate, reliable & trouble free float operated technique used in large non-pressurized storage tanks.


Principle

1) Guided & Direct Indication

The Float & Board Level Indicators consists of a float connected to a pointer through a rope via a set of pulleys. The pointer glides over a calibrated gauge board, positioned parallel to the tank. The float accurately follows liquid level variations in vertical direction. The horizontal float movement is restricted by two guide wires firmly anchored to tank bottom. As such, the pointer in ‘TOP POSITION’ when tank is ‘EMPTY’ and in ‘BOTTOM POSITION’ when ‘FULL’.

2) Unguided and Direct Indication

Construction for this type of Float & Board Level Indicator is similar to the above, except guide wires are not provided, as the horizontal float movement is negligible.

Float & Board Level Indicator

Model No. : MI - 09


The Float & Board Level Indicators are designed for an accurate, reliable & trouble free float operated technique used in large non-pressurized storage tanks.


Principle

Guided & Follower Magnetic Indication

The Float & Board Level Indicators consists of a float connected to a magnetized counter weight moving in a sealed SS Chamber, which in turn drives a follower magnet inside a cylindrical glass tube to indicate ‘LEVEL’. The pointer glides over a calibrated gauge board, positioned parallel to the tank. The float accurately follows liquid level variations in vertical direction. The horizontal float movement is restricted by two guide wires firmly anchored to tank bottom. As such, the pointer in ‘TOP POSITION’ when tank is ‘EMPTY’ and in ‘BOTTOM POSITION’ when ‘FULL’.



Gauge Classification

  • Measuring Range - 3 mtrs. with Ø200mm float
  • Float - SS304 x Ø200mm
  • Calibrated Gauge Board - SS316 x Ø200mm
  • Low Pressure - PP x Ø200mm
  • Medium Pressure - 4” wide x Al white powder coating with black graduations & red numericals
  • Least Count - 5mm
  • Maximum Temperature - 80°C (PP) / 150°C (SS)
  • Maximum Pressure - 5 Kg/cm2
  • Float Wire Rope - Ø1.6mm x SS 316 / SS 304 (multistrand) / Ø3mm x PP (multistrand)
  • Guide Wire Rope - Ø1.6mm x SS 316 / SS 304 (multistrand) / Ø3mm x PP (multistrand)
  • Installation - Grounded Level Tank / Underground Tank (sump) / Overhead Tank
  • Specific Gravity of Fluid - 0.75
  • Connecting Pipe - Carbon Steel Powder Coated

Protection Conduit

  • Horizontal Limb - GI pipe 25NB x 650mm to 1100mm (adjustable)
  • Vertical Limb - GI pipe 25NB x 285mm & 195mm long
