Principle of Level trol: Working of level trol is based on the Archemedes‘ principle which states that the resulting fluid pressure on the body acts vertically upward through the body’s center of gravity when a body is immersed in a liquid and…
Differential Pressure Transmitter (DPT) are used to measure level in process tanks which compares the pressure measurement between pressure at the bottom of the tank with atmospheric pressure, or pressure at the empty space at the top of the same tank. General…
Laser transmitters used for level measurement work basically on the same principle of operation as ultrasonic level sensors. The only difference is that the former uses speed of light while the latter uses speed of sound waves. Laser level measuring devices can…
The pneumatic level transmitter has the advantage of no leakage will matter to use in the process industry and the pneumatic signal can be feedbacked to control the pneumatic valve. Construction of Pneumatic level transmitter: The valve and float arrangement so the…
The paddle type level switch is used for the detection of dust level or litter material in silo, hoppar, etc. The rotating vane is continuously rotated by a motor. When this pallet comes into contact with the material, more force than the…
What is a float level detector? The float level detector is used to measure liquid levels in a tank in which a float rests on the surface of the liquid and follows the changing level of the liquid. Float-operated gauge level-indicator indicates the…
The selection of the right level measurement solution is based on not only the choice of measurement technology but also the application and installation requirements. Density and Viscosity: Viscosity and density considerations affect the selection of many liquid level switches and continuous…
A capacitor sensor works under the principle of capacitance. The capacitance sensor is one of the more recent developments in sensor and transducer technology. Its function depends on the characteristics and behaviour of the variable capacitor. The different application of Capacitor sensors are…
Principle: The basis of hydrostatic pressure measurement for the level is such that the measured pressure is proportional to the height of liquid in the tank, irrespective of volume. The pressure is related to the height by the following: P = h.ρ.g…
The basic method of nuclear level measurement is sending radiation through the liquid and the intensity of the transferred radiation is measured using a detector. The intensity of the radiation detected is the function of the level of liquid in the tank….
