Torque Tube Level Measurement
Torque Tube Level Measurement. A change in liquid level varies the net weight of the displacer (2), increasing or decreasing the load on the torque tube (4) by an amount directly proportional to the change in liquid level. Working of displacer level measurement:

The range spring and lvdt combination uses an lvdt core that moves as the spring is unloaded by having fluid on the displacer, causing voltages to be induced across the secondary windings and be converted to a level reading. If the level rises above the top of the displacer, the displacer cannot measure the level. Proven buoyancy and torque tube principles.
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 torque tube and the displacer must be properly sized for the application in order for 0 to 100% of displacer length to be available. A torque tube uses a torsion bar that rotates relative to the weight of the displacer in fluid to correspond to a level reading. Displacers with torque tube are common level measurement devices in industrial applications.
Density Difference Between 2 Liquids Is More Than 0.1 G/Cm³ Density Measurement:
Magnetrol's e3 modulevel® displacer transmitters have no torque tube but lvdt (linear variable differential transformer) which makes these units easy to use and eliminates old generation transmitters' disadvantages. Use the level measurement in this condition. 1) level measurement, 2) interface measurement, 3) density measurement:
Avoid The Twists And Turns Of Torque Tube Technology’s Performance, Durability And Maintenance.
The e3 modulevel’s lvdt range spring technology is the straightforward choice for accurate, reliable liquid level measurement and control. Asme class 150,300,600,1500 and 2500 Their complicated mechanical design causes a lot of problems in use.
The Torque Tube Assembly Consists Of A Hollow Torque Tube With A Shaft Welded Inside It At One End And
The leveltroll works on the buoyancy principal. The design of the torque tube varies from manufacturer to manufacturer. If the level rises above the top of the displacer, the displacer cannot measure the level.
