- Low-power RS485 design: 10000mA 5V battery, which can theoretically be used for more than 3 years;
- Using waterproof and anti-corrosion materials, the protection level reaches IP68, especially suitable for water level monitoring applications in rivers and wells;
- The intelligent data terminal can be powered on to enter the working state, and can control the data transmission state.
2.Introduction
The anti-corrosion ultrasonic level gauge is a digital level gauge controlled by a microprocessor. In the measurement, the pulsed ultrasonic wave is sent by the sensor (transducer), the sound wave is reflected by the surface of the object and received by the same sensor, converted into an electrical signal, and the distance between the sensor and the measured object is calculated by the time between the emission and reception of the sound wave. . Because the anti-corrosion ultrasonic liquid level gauge adopts non-contact measurement, the measured medium is almost unlimited, and it can be widely used in the measurement of the height of various liquid and solid materials.

6.More information
The ultrasonic object/liquid level meter is installed on the upper part of the container. Under the functional control of the combination unit and electronic components, the probe emits a beam of ultrasonic pulses above 20000Hz to the measured object. Since temperature has an effect on the speed of sound, the meter should measure the temperature to correct for the speed of sound. There are many options for the four-wire system, which can simultaneously bring 4-20mA, RS485 communication, two relay outputs, and can also be powered by 220VAC.
