1. What is mlc?
mlc is the unit of meter liquid column. The following is a detailed introduction to mlc: Definition: mlc is an abbreviation for "meter liquid column" in English, which is used to represent the unit of pump head. Conversion relationship: In pressure unit conversion, 1mlc is equal to 0.01 megapascals. Application scenario: In the relevant parameters of the pump, the pressure head of the centrifugal pump is commonly represented by mlc, which reflects the effective energy obtained per unit weight of liquid flowing through the pump.
2. What are the performance characteristics of ultrasonic liquid level sensors?
Ultrasonic level gauges can adopt two-wire, three wire, or four wire technology. The two-wire system is: power supply and signal output are shared; The three wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24V power supply, a 3-core cable can be used, and the negative end of the power supply and the negative end of the signal output share the same core wire; The four wire system is: when using AC 220V power supply, or when using DC 24V power supply and requiring complete isolation between the power supply circuit and the signal output circuit, a 4-core cable should be used. DC or AC power supply, with 4-20mADC and high/low switch output. The range of the split type ultrasonic level gauge is 0-50 meters, with multiple forms to choose from, suitable for various corrosive and chemical applications, high accuracy, remote signal output, and PLC system monitoring. The working principle of an ultrasonic liquid level meter is that high-frequency pulse sound waves are emitted by an ultrasonic transducer (probe) and reflected back on
3. Product Introduction of Ultrasonic Level Gauge
Ultrasonic is a type of sound wave that goes beyond 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
