русскийOrdinary liquid level transmitters are used to measure the level of liquid in tanks, vessels, and other containers. They are widely used in the chemical, petrochemical, food and beverage, and pharmaceutical industries, as well as in water and wastewater treatment facilities. In this article, we will provide an in-depth explanation of how ordinary liquid level transmitters work.
Ordinary liquid level transmitters use a variety of technologies to measure the level of liquid in a container. One of the most common technologies used is the hydrostatic pressure measurement. In this method, a pressure sensor is placed at the bottom of the container and measures the pressure exerted by the liquid. As the level of liquid increases, the pressure on the sensor also increases. The pressure sensor converts the pressure into an electrical signal, which is then transmitted to a display or control system.
Another common technology used in ordinary liquid level transmitters is the ultrasonic measurement. In this method, a transducer emits ultrasonic waves that bounce off the liquid surface and return to the transducer. The time it takes for the waves to travel back to the transducer is used to calculate the distance between the transducer and the liquid surface, and hence the level of liquid in the container.
Capacitive level measurement is also used in ordinary liquid level transmitters. In this method, a probe is placed in the liquid and acts as one plate of a capacitor, while the container wall acts as the other plate. The capacitance is proportional to the level of liquid in the container, and is used to calculate the level of liquid.
In conclusion, ordinary liquid level transmitters are an essential tool for measuring liquid levels in a wide range of applications. By using various measurement technologies, such as hydrostatic pressure, ultrasonic measurement, and capacitive level measurement, these devices provide accurate and reliable level measurements. Understanding how these devices work is critical to ensuring their proper operation and maintaining their accuracy over time.
