It is an economical mechanical gauge provides high accuracy in mm. Largely used in Refineries, Oil Depots, Chemical and Fertilizer Industries. Useful for medium and large size charged or empty tanks. It may be cone roof, floating roof, underground or gas holding tank. It covers critical applications like corrosive & aggressive acids (using non-metallic wetted parts) & liquids with fumes (using vapor seal).
It requires very less maintenanceOnce carefully installed gives trouble free operations for a number of years (with periodic maintenance). A specially designed cylindrical body floats on liquid surface on account of its buoyancy. The liquid level is transmitted by means of a tape connected to float on one side and gear mechanism on the other side. Gears rotate the pointer on a dial or counter mechanism to display readings.
