Boiler Water Level Control System Example | Introduction

Oct 31, 2019 · The purpose of this instrument is to compare the level transmitter's signal against a setpoint value entered by a human operator representing the desired water level in the steam drum. The controller then generates an output signal telling the control valve to either introduce more or less water into the boiler to maintain the steam drum water level at setpoint. As with the transmitter, the …

Automatic Water Level Controller Working Principle (W

Mar 21, 2017 · These automatic water level controllers are used to automatically fill the over-head tank when it starts or has become empty as well as monitor the water level in it. Automatic water level controllers switch the motor on whenever the water level drops below a certain level and shuts the motor off when the water rises well above a fixed level. The motor will also switch off when the sump water is exhausted before it fills the …
