Displacer type level transmitter calibration / Leveltroll Calibration

2 minutes of reading

Introduction Leveltroll is a combination of torque chamber, torque arm, torque tube, displacer and with this mechanism we can measure the level.A Leveltroll in and instrument used for measuring the liquid level between two known points. The Leveltroll works on the buoyancy principal. Leveltroll has a float, which submerses proportionately with liquid level raise in …

Absolute Pressure – A quantity of pressure measured with respect to total vacuum. Equal to the sum of a pressure gauge reading and atmospheric pressure (14.69 psia or 1.01 bar at sea level).  Absorption – The “soaking up” of gas, liquids or dissolved substances into a solid material.  Acid – A chemical compound that dissociates …

How does a Level troll work? Name the parts of a pneumatic Level troll.   

4 minutes of reading

Displacer level instruments use the Archimedes Principle to measure the level of a liquid by measuring the weight of a rod that is immersed in the process liquid. As liquid level rises, the displacer rod experiences a greater buoyant force, appearing lighter to the sensing instrument, which interprets the loss of weight as a rise …
