DISPLACER LEVEL MEASUREMENT
APM Pneumatic Modulevel® For Boiler Feed Systems
The APM Pneumatic Modulevel® series are displacer actuated level controls specifically designed for boiler service that provide output signals in direct proportion to changes in liquid level.
Operating Principle
As the buoyancy force on a displacer changes with liquid level movement, a range spring supporting the displacer extends or compresses, moving a magnetic ball. A magnet carriage within the controller head follows the ball producing a change in output.
Applications
Feedwater heaters
Steam drums
Deaerators
Hot wells
