Anticorrosive ultrasonic level gauge

The anti-corrosion ultrasonic level gauge is a very commonly used measuring tool for level measurement of corrosive media on the market. As a non-contact level gauge, it has unique functions that traditional level gauges do not have. Because it will not come into contact with the medium, it is often used in some specific corrosive medium liquid level measurement occasions. If you are interested in this, then you must have an understanding of the principles, applications, characteristics, and parameter selection of ultrasonic level gauges.　　 First is the basic principle of ultrasonic level gauge. The ultrasonic level gauge is a digital level gauge controlled by a microprocessor. The ultrasonic level gauge is composed of three parts: ultrasonic transducer, processing unit, and output unit. In the measurement, the ultrasonic pulse is emitted by the sensor (transducer), and the sound wave is reflected by the liquid surface and then received by the same sensor or ultrasonic receiver, converted into an electrical signal by a piezoelectric crystal or magnetostrictive device, and transmitted and received by the sound wave The time between to calculate the distance from the sensor to the surface of the liquid being measured.　　The second is the application. Due to the non-contact measurement of the ultrasonic level gauge, the measured medium is almost unlimited, and it can be widely used for measuring the height of various liquids and solid materials. Common application conditions, such as manholes, factory water tanks, tanks, municipal engineering, tap water, sewage treatment, water conservancy and hydropower, steel, coal, electricity, petrochemical, urban rivers and lakes, transportation and food processing industries.　　 Next is the characteristic, the ultrasonic level gauge has the following major advantages. 1. Automatic power adjustment, gain control, temperature compensation 2. Physically sealed, integrally sealed with the housing to prevent the probe from affecting the performance of the whole machine when the probe is damp 3. Waterproof design, streamlined housing, working in the open air, rainwater cannot enter the housing along the cable , Avoid the internal circuit from being damp. 4. Multiple output forms: programmable relay output, high-precision 4-20mA current output, Rs-485 digital communication output split ultrasonic level probe 5. Strong anti-interference. The upper and lower limit nodes and online output adjustment can be set arbitrarily, with on-site display, analog quantity, switch quantity and RS485 output can be selected, and it is convenient to interface with related facilities.　　 Finally, there are parameters and selection. Taking the most common parameters, measuring ranges, the common ones are 5m, 10m, 15m, 20m, 30m, 40m, 50m, 60m. In addition to the range, there are other accuracy. Theoretically, there are two levels of accuracy: 0.5% and 1%, but in reality, because of different field conditions, the accuracy tends to be poor. In addition, there are output signals, which can be divided into analog output, digital output, and relay output. The analog output can be divided into 2-wire 4-20ma output, 4-wire 4-20ma output, digital output can be RS485, RS232, relay output can be AC250V/5A or DC30V/5A. In addition, there is power supply, standard 24vDC, optional 220v, 50Hz. The last is installation, which can be divided into thread and flange installation.　　 In summary, it is the principle, application, characteristics, and parameter selection of the anti-corrosion ultrasonic level gauge. I believe that after reading it, you must have a general understanding of the anti-corrosion ultrasonic level gauge, right? At present, there are more of the ultrasonic level gauges in the market, which is the model of Kaidi MIK-DP. If you want to know or purchase , It is recommended to look for this directly.
Nowadays, the adoption of level gauge in customized level indicator industry is quite common.
If you already use level gauge elsewhere or want the ability to offer restricted chat access to certain individuals, level gauge customized level indicator offers you the most flexibility.
