  1. Overview of Liquid Level Control Systems A  liquid level control system  is a system used to measure, monitor and control the height of liquid in a container. It mainly adjusts the inlet and outlet of liquid by measuring the height of the liquid to keep the liquid within the set liquid level range. 2. Working Principle of Liquid Level Control System Liquid level control systems usually consist of the following components: sensors, controllers and actuators. Here is how the liquid level control system works: 2.1 Sensors The liquid level sensor is one of the most critical parts of the liquid level control system. It usually measures the height of a liquid through physical or electronic methods and converts the measurement results into electrical signals. 2.2 Controllers The controller is the central component in the liquid level control system, responsible for receiving signals from sensors and processing and making judgments. According to the set liquid leve...

  Capacitive Level Transmitter  Overview: Smart capacitive level transmitter  meter is suitable for the level of conductive and non-conductive liquids(solids) in containers. It uses the capacitance change of the capacitor to measure the liquid level of the medium in the container,and has nothing to do with the temperature,pressure,density,container shape and other parameters of the measured medium, and can output 4–20mA two-wire standard current signals, and superimpose HART protocol signals. It is widely used in chemical industry, petroleum, metallurgy, light industy, food, power, energy and other fields. Product Features: 1. Two-wire current loop, non-polarity input, current loop and measurement system are isolated; 2. Complies with HART communication protocol and equipped with a dedicated handheld operator; 3. No manual intervention is required for setting on site, automatic calibration, no calibration, and automatic adaptation to changes in the medium; 4. It has the f...

  Reservoirs undertake many functions such as flood control, irrigation, and hydropower generation, so the monitoring and dispatching of their water levels are very important. Although mechanical floats, pressure sensors and other equipment play a certain role in traditional water level measurement methods, they have problems such as poor measurement accuracy and high maintenance costs. With the advancement of science and technology,  radar water level gauge , as a new type of water level monitoring tool, has gradually been widely used in reservoir water level monitoring due to its characteristics of high precision and non-contact measurement. Next, let's discuss the important role of radar water level gauges in reservoir water level monitoring. How radar water level gauge works: The radar electromagnetic wave is emitted from the radar water level meter antenna, and the antenna receives the electromagnetic wave reflected from the water surface. The radar water level meter can ...

  Radar Level Gauges Applications and Challenges in Liquefied Gas Level Measurement The traditional measuring instrument in liquefied gas storage tanks is the servo level gauges, which use a float and motor drive system to measure liquid level. However, they also have some disadvantages.   First, due to the presence of multiple moving parts inside, it is susceptible to mechanical wear and tear, leading to an increased failure rate and a low mean time between failures, usually only about five years.   In addition, changes in the density of the liquid will cause changes in the buoyancy of the float, thereby affecting the measurement accuracy of the liquid level. Servo level gauges also require regular calibration and extensive spare parts support, increasing maintenance costs.   With the development of science and technology,  non-contact radar level gauges  have gradually replaced servo level gauges and become the mainstream choice for liquid level measureme...

Through the study of different types of commonly used liquid level gauges in 2 chapters in the past two weeks, we have a better understanding of common liquid level gauge types. Today we will discuss the remaining common liquid level gauge types and principles in the last chapter. By learning and understanding the common types of liquid level gauges, we hope to deepen our practical application. Electric Contact Level Gauge The electric contact water level gauge is designed according to the different resistivity of water and steam. The electrode of the measuring cylinder has a small impedance to the cylinder in water. In which the resistance to the cylinder is large. As the water level changes, the number of electrodes in the water changes. Convert to a change in resistance value. Transfer to the secondary instrument, so as to achieve the water level display, alarm, protection interlock and other functions. Magnetic Sensitive Electronic Two Color Level Meter The magnetic sensitive elect...

  We briefly explained the names and principles of the 7 types of common liquid level gauges in Chapter 1 last week. Today we will continue to explain the other 6 common types of liquid level gauges in Chapter 2 one by one: Glass Plate Level Gauge  (Glass Tube Level Gauge) The glass plate type liquid level gauge is connected to the container through a flange to form a communicating vessel. The height of the liquid level in the container can be directly read through the glass plate.   Pressure Level Transmitter The pressure level gauge adopts the static pressure measurement principle. When the liquid level transmitter is put into a certain depth in the measured liquid, the sensor is subjected to the pressure of the liquid surface. At the same time, the pressure of the liquid is introduced into the positive pressure cavity of the sensor through the gas-conducting stainless steel. Then the atmospheric pressure Po on the liquid surface is connected to the negative pressure ca...
