Custom built assemblies can be provided for specific applications.

SPECIFICATIONS :

1) Guided x Direct Indication : (Fig. 1 overleaf) It 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 is in 'TOP POSITION' when tank is 'EMPTY' and in 'BOTTOM POSITION' when 'FULL'.

Applications : Liquid storage tanks having moderate turbulence and tank heights upto 15 metres.

2) Unguided x Direct Indication : Construction is similar to (1), except guide wires are not provided, as the horizontal float movement is negligible.

Applications : Liquid storage tanks having minimum turbulence and tank heights upto 3 metres.

3) Guided x Follower Magnet Indication : (Fig. 2 overleaf) Construction is similar to (1), except float is connected to a magnetized counter weight moving in a sealed SS Chamber, which in turn drives a follower magnet (capsule) inside a cylindrical glass tube to indicate 'LEVEL'.

CONSTRUCTION & OPERATION :

Applications : Liquid storage tanks having corrosive fumes / vapours, as well as tanks having pressure maximum upto 1kg / cm² & also for Nitrogen Purged Solvent Tanks.

It is an accurate, reliable & trouble free float operated technique used in large non-pressurized storage tanks.
