1. Product Introduction of Ultrasonic Level Gauge

Ultrasonic is a type of sound wave that exceeds the range of human hearing. Like sound waves, it also undergoes reflection, refraction, and transmission when propagating in different media. Ultrasonic level gauge utilizes the principle of reflection. Firstly, the ultrasonic probe emits an ultrasonic pulse in the air, which is reflected back when it encounters an obstacle. The echo is then received by the probe, and the control unit calculates the actual distance from the emission point to the obstacle based on the time difference between transmission and reception. This is the principle of ultrasonic ranging. In areas with foggy and humid air, where condensation occurs. Or for certain specific industries, such as gas purification and circulation water absorption wells, the water comes from the process cooling equipment (such as primary and final cooling towers) in the chemical production workshop. The water temperature is generally around 50 degrees, and then cooled to around 40 degrees through a drying tower before being sent into the gas purification and circulation water absorption well. Due to the high humidity and moisture inside the well, and the fact that the temperature of the water is higher than that of the liquid level gauge probe (especially the temperature difference between day and night inside and outside the well is greater), we can see the phenomenon of condensed water droplets adhering to the probe. The water droplets attached to the probe cause the ultrasonic waves emitted by the probe to refract, resulting in an incorrect time difference between transmission and reception, and then the meter control unit calculates the incorrect liquid level

. To address the issue of water droplets and condensation affecting liquid level measurement for water industry users, we have launched the LT-200 ultrasonic level gauge from the Korean brand LETECH. In foggy and humid areas, rainy days, or when condensation occurs due to temperature differences, ultrasonic measurement is not possible. This product uses a circular arc shape in the sensor to quickly gather condensation at the center of the surface, causing it to automatically drip. The surface vibration of 5 times per second can vaporize water molecules, thus solving various problems that occur during condensation. (Patent Office Practical New Case Registration: 20-044-0512).

2. What is mlc?

mlc is the English abbreviation for the unit of meter liquid column.

. Here is a detailed explanation of the mlc unit:

1. Define mlc, also known as "meter liquid column", which is a unit used to represent liquid pressure or pump head. Mlc is an important unit in the working parameters of pumps, especially when describing the head of centrifugal pumps.

Secondly, the expression of centrifugal pump head: The head of a centrifugal pump, which is the effective energy obtained per unit weight of liquid flowing through the pump, can be expressed in mlc.

. It reflects the ability of the pump to do work on the liquid and is one of the important performance indicators of the pump. Liquid pressure measurement: In liquid pressure measurement, mlc can also be used as a reference unit to describe the pressure magnitude of the liquid.

Thirdly, there is a conversion relationship between mlc and other pressure units. For example, 1mlc is equal to 0.01 megapascals (MPa). This conversion relationship allows for e
