The wall-mounted ultrasonic liquid level differential meter is a new generation of ultrasonic level measurement instrument independently developed by our company based on the actual needs of the water conservancy and hydropower industry and years of measurement and control experience. It adopts advanced embedded microprocessing technology, achievinga high degree of digitalization and intelligence. This non-contact liquid level differentia lmeasurement instrument integrates ultrasonic sensors, servo circuits, temperature compensation circuits, and operation hosts. It features high precision, long service life,stability and reliability, and is easy to install and maintain. It is widely used in the measurement of liquid level differences before and after grilles in rivers, lakes, water gates,ship locks and other industries.
It features high measurement accuracy, easy installation, and adaptability to various environments. It is not affected by weather or other factors.
The transducer is a combined transmitter and receiver, capable of accurately receiving weak echo signals.
The unique filtering processing function can automatically identify true and false echoes.
It features point-by-point temperature compensation, which enhances measurement accuracy and adaptability to working conditions.
The liquid level difference can be directly displayed on the LCD and can also output remote transmission signals.
It features 4 groups of relay outputs and can be used for liquid level differential segment control or on-off control (optional).
It features serial data output or 4~20mA output or 0~5V analog signal and 1~5V analog signal.Output (Optional when placing an order)
Optional upper-level software can be selected to directly monitor each point in real time on a PC.
It features a 4mA, 20mA digital fine-tuning function for liquid level difference, making the debugging process extremely convenient and fast
It has the function of arbitrary digital translation of the full-scale starting point and end point.
Equipped with liquid level mode and liquid level difference mode functions
Support SD card data storage, GPRS wireless communication (optional when placing an order)
