Float And Board Type Level Indicator

/> </div> <div class=
FEATURES:-
It is a simple, accurate , maintenance free & reliable float operated technique adopted for tank gauging in large Non pressurized storage tank where to get a level within 1" or 2" of liquid level is satisfactory and provides the additional convenience of being able to read out at 100 or 200 ft. away from the tank.
Material of construction available.

Float moves up & down during a rise in liquid level and vice-versa. So that the pointer is at bottom position during full tanks and the top position during empty condition. In case of magnetically coupled reading, the float is connected to a magnetic counter weight, moving within a sealed S.S. chamber, the follower magnetic capsule inside a transparent glass tube to give level indication. This concept is adopted for volatile liquids with relatively high vapour pre
