Float & Board Type Level Indicator
Float & Board Type Level Indicator

Product Templates Item Code: MECH_FAB

Float & Board type level gauge is a weighing liquid level measuring system applicable for non-pressurized storage tanks/vessels. It is basically a balanced counterweight system with an arrow shaped pointer which smoothen the indication process. It is suitable for most liquid application media whose specific gravity is ≥ 0.8. Additionally, it effectively works in the phenomena of turbulence by ensuring stability using guided rope assembly with an anchor.
  • Installation available for Ground Level Tank, Overhead Level Tank and Underground Level Tank.
  • Wide Range Tank Height: Guided (up to 20m), Non-Guided (up to 8m)
  • Float Ø 280mm × 80mm (SS 316 with Tested Pressure 2kg/cm²)
  • Specific Gravity ≥ 0.8
  • Application Temperature Range : Up to 100° C
  • Adjustable Horizontal Pipe (500 to 1000 mm)
  • Wetted Parts : SS 316
  • Weatherproof Scale Board (SS 304 & Pure Polyester Powder Coated Aluminum)
  • Process Connection: Flanges
  • Radium Visibility from longer Distance
  • Price Range: INR 15000 to 40000 Validity: 6 Months
    Stock Unit: Nos

Operating Principle

The working principle of Float & Board level indicator is based on the buoyancy principle and is linked as per balanced counter weight system. float inside the tank and counter weight (scale pointer) connected by the rope wire which is moving freely on the pulley assembly. When the storage tank is in empty position, the float located inside the bottom of the scale pointer located at zero level on external scale. If the liquid level rise in the tank, the float move upper side and scale pointer move downward on the graduated scale to show liquid level inside the storage tank. If liquid level turbulance inside the tank use float guide rope wire assembly with anchor for stability of float.

Water Storage Tank

Water is the very important part of human life. Water Storage Tanks are used to provide water for use in many applications like drinking water, fire suppression, and many more. Water storage tank helps with clean water distribution in rural areas.

Float and Board liquid level indicator continuously measure the water level to maintain the accuracy of the water storage tank. Easy to maintain; Float and Board Level indicator is an ideal match for remote and rural areas with limited or no availability of electricity.
