Tasememõõturid

Tasememõõturid are devices used to measure the level of a substance within a container or tank. These instruments are essential in various industrial and domestic applications for monitoring and controlling fluid levels, preventing overflows, and ensuring efficient operation. There are several types of tasememõõturid, each employing different principles of measurement.

One common type is the float-based tasememõõtur. This device utilizes a buoyant object that rises and falls with the substance's level. The movement of the float is then mechanically or electronically translated into a level reading. Another category includes hydrostatic tasememõõturid, which measure the pressure exerted by the liquid column. This pressure is directly proportional to the height of the liquid, allowing for accurate level determination.

Capacitive tasememõõturid work by measuring changes in capacitance caused by the substance between two electrodes. As the substance level changes, it alters the dielectric properties between the electrodes, resulting in a measurable change in capacitance. Ultrasonic and radar tasememõõturid are non-contact methods that emit sound waves or radio waves, respectively, and measure the time it takes for the waves to reflect off the substance's surface. The time of flight is then used to calculate the distance to the surface, and thus the level. The choice of tasememõõtur depends on factors such as the type of substance, operating temperature and pressure, required accuracy, and cost.
