|  Instrument usage The LSQ ultrasonic open channel flowmeter is mainly used for measuring the flow in dry rivers with free flow conditions, irrigation channels, factories, urban sewage drainage ditches, and non full pipe pipelines. When the instrument is working, the sensor does not come into contact with the measured fluid, avoiding contamination and corrosion by sewage in the channel. Used for measuring sewage flow, it has higher reliability compared to other forms of instruments. This flowmeter adopts ultrasonic measurement, microcomputer processing, and large screen digital display, and can be installed and automatically measured in harsh environments. The adoption of oscilloscope technology enables instruments to have high reliability and strong anti-interference ability. Easy installation and maintenance, easy to read. Widely used for measuring sewage discharge from industries such as dry petroleum, chemical, textile, and pharmaceutical, it is one of the main instruments for urban pollution prevention and environmental protection departments to monitor sewage discharge from enterprises and institutions. It is also an instrument for measuring agricultural irrigation water discharge. Main Features 1、 Large screen LCD backlight display with large information capacity, capable of displaying instantaneous flow rate, cumulative flow rate, liquid level, time, and instantaneous flow bar on the same screen. 2、 This instrument has data storage functions for hourly, daily, monthly, annual flow and power outage information. The stored data is not lost in case of power failure, and can be viewed through the buttons on the instrument panel. It has automatic temperature compensation and environmental temperature display functions. 3、 The oscilloscope technology, also known as signal environment display, can clearly display the waveforms of the emitted waves, reflected waves, and interference waves of ultrasonic waves. The application of oscilloscope technology makes this process clear and visible, enhancing the usability of the instrument. 4、 When applied to narrow channels, the interference echo generated by the channel sidewall has no effect on this instrument. It is currently an instrument that uses wave difference level and oscilloscope technology to achieve suppression and anti-interference ability against the interference echo.
