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’.
