Boiler Water Level Control System Example | Introduction

Oct 31, 2019 · The first instrument in this control system is the level transmitter, or "LT". The purpose of this device is to sense the water level in the steam drum and report ("transmit") that measurement to the controller in the form of a signal. In this case, the type of signal is pneumatic: a variable air pressure sent through metal or plastic tubes. The greater the water level in the drum, the more air pressure output by …

Jan 02, 2015 · The greater the water level in the drum, the more current signal output by the level transmitter. The level transmitter output will be in range of 4 to 20mA signal where 4mA is equal to 0% level signal and 20mA is level signal. The level transmitter will sent this measured level signal in the form of 4-20mA to the control system (PLC/DCS).
