KUM2500A Non-contact maintenance-free ultrasonic clamp level sensor for diesel / oil / water tank
Introduction
KUM2500A a sensor device that uses ultrasonic detection technology to measure the non-contact liquid level height of oil and liquid substances. It has a built-in anti-interference data processing model to intelligently filter and compensate for environmental interference. It is suitable for containers of various materials such as metal and plastic. It can be networked to realize network monitoring. manage. With the characteristics of fast response, low power consumption and small blind zone, it is specially designed for fuel consumption detection; distribution installation accessories include fixing brackets, and the sealant is firmly attached. Intelligent temperature drift compensation, to ensure that the output value of the corresponding liquid level at different temperatures is the same, temperature drift compensation is required, the sensor is placed in a constant temperature box, the temperature changes continuously from -40°C to 80°C, and detailed data is recorded to obtain a temperature drift change table; High linearity: built-in intelligent processing chip, which can set corresponding parameters according to the vehicle's operating road conditions to overcome the problem of data fluctuations.
Working Principle
KUM2500A ultrasonic level sensor uses the ultrasonic echo ranging principle. The sensor is installed on the outer surface of the bottom of the fuel tank, and sends out ultrasonic signals from the bottom. When it encounters the liquid surface, it reflects back, and then calculates the liquid level height according to the time and speed. At the same time, combined with digital signal processing technology, it overcomes the influence of the container wall, realizes high-precision non-contact measurement of the liquid level in the container, and can meet the requirements of industrial applications in application.
