Brief introduction: Ultrasonic water level meter is composed of ultrasonic probe and electronic unit. The ultrasonic water level meter is installed above the water surface. Under the control of the electronic unit, the probe sends an ultrasonic pulse to the measured water surface. Sound waves are reflected by the surface of the water, and part of the reflected echoes are received by the probe and converted into electrical signals. Working principle: Ultrasonic water level meter is composed of ultrasonic probe and electronic unit. The ultrasonic water level meter is installed above the water surface. Under the control of the electronic unit, the probe sends an ultrasonic pulse to the measured water surface. Sound waves are reflected by the surface of the water, and part of the reflected echoes are received by the probe and converted into electrical signals. The time from ultrasonic emission to rereception is proportional to the distance from the probe to the water surface under test. The electronic unit detects the time and calculates the measured distance based on the known sound velocity. The water level can be obtained by subtraction. Product features: By using the updated transducer structure and manufacturing technology, the working life and corrosion resistance of the transducer are extended, and the working performance of the transducer is significantly improved. Microprocessor program control, intelligent signal processing technology, can achieve a variety of typical working condition software processing mode, so that the level meter can be widely used in various industrial fields (such as solid, liquid, dust and other complex working conditions), easy to install and maintain. Table head key programming Settings, simple and reliable operation, no programmer. Small and beautiful appearance, easy to install. The application of new technology and new materials has created new technology products that combine reliability and economy. The transducer has built-in temperature sensor, which can realize temperature compensation of measured value. Technical parameters: Measurement range: 0~40m Accuracy: level 0.2, level 0.5 Current output: 4~20mA or RS485 Power supply: 12VDC or 24VDC or 220VAC Installation: thread, flange or bracket Parameter setting: 3-bit sensible button Temperature range: - 40 ℃ ~ 80 ℃ Temperature compensation: full range of automatic compensation Pressure range: 0.1mpa Detection period: 1.5 seconds Protection level: IP67 Installation: thread, flange or bracket
