Industrial Grade Remote Level Indicators are used for water level/ liquid level indications and this facilitates the user to detect water-level fluctuations in the boiler drum and is delicately designed to provide flawless indications. The Indicators are accurate and helps users to track the displacement of water levels in the boiler and the increasing water column in the boiler presses the red indicating liquid from the first phase into second phase and then indicates in the inspection glass of the indicator. The Indicators have the feature that the displaced water from phase one flows into phase three and then into the boiler through the condenser. The Industrial Grade Remote Level Indicators ensures that the liquid in the inspection glass also falls when the water level in the drum is reduced.
