是一种非接触式物位检测仪器。 Ultrasonic level gauge is a non-contact level detection instrument. It is directly installed above the measured medium, and adopts a low-power integrated ultrasonic sensor. Based on the principle of measuring time difference, the microprocessor performs signal processing and precise calculation to measure the level of the liquid. Suitable for small range measurement within 0-3.5 meters. Output 4-20mA, 0-5V, RS485, RS232 and other standard signals. Mainly measure liquid level, such as river water level, waste water level, canned liquid level, mud, etc., has been widely used in sewage treatment, power plants, Chemical plants, steel mills, pharmaceutical plants, wineries, various chemical plants. The performance meets international standards and is an ideal choice to reduce costs and replace imported products.

Technical advantages of ultrasonic level gauge: Ultrasonic level gauge is a non-contact measurement method, ± 0.2% accuracy, 1-25 meters range, excellent focus: 5 degree sound beam angle, multiple sensor materials, built-in full-range temperature compensation. Ultrasonic level gauges measure corrosive (acid, alkali) media, polluted places (sewer), or substances prone to adhesions. Suitable for liquids that cannot be physically contacted.
The components of the ultrasonic level gauge: ultrasonic transducer, processing unit, output unit. The ultrasonic level gauge is an ideal measuring tool for corrosive, layered or acid-base wastewater. Ultrasonic level gauges can measure media such as hydrochloric acid, sulfuric acid, hydroxide, wastewater, resin, paraffin, mud, lye and bleach. They are widely used in water treatment, chemical industry, power, metallurgy, petroleum, semiconductor. And other industries.
的优点 Advantages of ultrasonic level gauge
1. Non-contact measurement
2.No moving parts, simple structure and long service life
3.Corrosion resistance (most probes use PVDF, PP and other materials)
4.Automatic temperature compensation function
5, not affected by the humidity and viscosity of the medium
6.Not affected by dielectric permittivity, electrical conductivity, and thermal conductivity
7.Excellent cost performance
8.Precautions for ultrasonic level gauge
9, temperature resistance is limited, most of less than 60 ℃, some special products can reach 100 ℃
10. It is impossible to measure under vacuum environment, the large fluctuation of pressure affects the measurement accuracy
11, try to avoid interference factors such as bubbles, obstacles and waves during installation
