Working Principle of Level Transmitter The working principle of level transducers mentioned above is different depending on their underlying principle. For instance, Capacitor-based level transducers work through a capacitor, which is charged by the application of an electrical voltage across it. On the other hand, ultrasonic level transducers work through the movement of air bubbles through them, thus producing the vibration frequency that is measured by the level meter. As mentioned above, Check out the working principle also varies according to the underlying principle. For example, Capacitor based level transducers work through a capacitor, while ultrasonic level transducers work through the airflow of a compressed gas, while the latter uses the air pressure of the same to measure the distance.
How to Use a Level Transmitter
How to Use a Level Transmitter One can use a level transmitter for various purposes such as tank level measurement in a chemical process, tank level measurement at the bottom of the tank and so on. First of all, when the tank’s bottom is not yet filled up, place a level transmitter in the tank. Then, place another transmitter on the surface of the tank. When the first one picks up the vibration from the surface of the tank, the second one will measure the distance. This is how the two transmitters work together!
The Benefits of Level Transmitter Level transmitters are widely used in various fields because they are reliable, accurate and convenient. While they may have limitations in some field, such as tank level measurement in chemical processes, they are otherwise flexible and convenient instruments. For example, they are used for non-contact ultrasonic liquid level calibration. Moreover, the transmitter has an automatic shut-off system, which ensures maximum protection of the equipments. Other possible limitations of this instrument include frequency accuracy, short battery life and weight.
