1. Multi channel ultrasonic time-of-flight flowmeter

Multi channel ultrasonic time-of-flight flowmeter is a device based on the velocity area method measurement principle, suitable for measuring the flow rate of various liquids, especially for pure or less impurity liquids, with advantages such as high accuracy, strong stability, and multi-channel measurement. The following provides a detailed introduction from the aspects of principle, performance, application, composition and installation: Measurement principle, applicability of time difference method: From the perspective of ultrasonic measurement principle, time difference method calculates the flow velocity by measuring the time difference between the forward and backward propagation of ultrasonic waves in the fluid, and then obtains the flow rate. It is suitable for measuring liquids that are pure and have relatively few impurities, such as tap water, river seawater, wastewater treatment plant effluent, etc. Excessive impurities can greatly affect the propagation speed and direction of ultrasonic waves, leading to increased measurement errors. In contrast, Doppler method is suitable for measuring liquids and slurries with high impurity content, such as urban drainage, mud, slurry, etc. However, the quantitative indicators for the impurity content of the measured medium in the two current measurement methods are relatively unclear, mainly due to the lack of effective instruments and meters for measuring the impurity content of liquids. The main performance has a wide range of applications: it is suitable for measuring flow velocity and flow rate at a 45 degree angle across various rivers and channels, and can meet the measurement needs in different scenar

ios. Rich interface: The host is equipped with multiple interfaces, which can be connected to various RTUs (remote terminal units) or liquid level meters, making it easy to integrate with other monitoring systems and achieve data sharing and remote transmission. Advantages of multi-channel measurement: Each independent intelligent measurement module ensures fast, accurate, and stable multi-channel measurement. Multi channel measurement can obtain flow velocity information at different positions, and through comprehensive calculation, obtain more accurate average flow velocity, thereby improving the accuracy of flow measurement. Data recording function: It has automatic recording and storage functions for power failure and power on, which can ensure the integrity and continuity of data. Even in the event of equipment power failure, important measurement data will not be lost. This diagram illustrates the installation of a multi-channel ultrasonic time difference flowmeter in practical applications. By installing sensors at different positions, the measurement of channel or river flow can be achieved. The main components of the installation include telemetry terminal, sensors, host, as well as installation accessories and cables. The telemetry terminal is responsible for data collection, processing, and transmission; Sensors are used for transmitting and receiving ultrasonic signals; The host analyzes and calculates the signals collected by the sensors to obtain flow data. Installation requirements for trapezoidal river channels: When installing multi-channel sensors in trapezoidal river channels, they should be installed on different sections. This can obtain flow velocity information at different locations and improve me
