Electronic water level gauge is designed to effectively assist in monitoring water level changes in complex water level monitoring scenarios, providing accurate water level information for monitoring units. This product adopts advanced production technology and protective shell, and has the characteristics of low power consumption and high reliability. The equipment has high measurement accuracy, stability and reliability, easy to use, and automatic reporting. Currently, it is mainly suitable for water level monitoring in urban waterlogging and flood control.
ADV-4/5 Portable Ultrasonic Doppler Flowmeter
◆Measurement principle The product utilizes an underwater ADV ultrasonic Doppler flowmeter/current meter as the sensor for measuring flow velocity, flow rate, and water level. The handheld terminal is equipped with a color LCD screen and features a built-in lithium battery for self-power supply, while also supporting external power supply from a power bank, greatly facilitating field operations. The modular wading rod enables highly convenient an d flexible operation under various working conditions. Additionally, the product comes with a portable carryi ng case that can be either hand-carried or worn as a backpack.
ATD Wireless Ultrasonic Time-of-Flight Cross-S ectional Flow Velocity Meter (20-200 meters)
Measurement Principle In water bodies with a surface width of less than 200 meters, the direct ultrasonic wave demonstrates high effectiveness during transmission. Based on this principle, a set of underwater sonar sensors can be i nstalled on both the left and right banks of the river at approximately 45-degree angles to receive direct ult rasonic wave signals whose speed is influenced by water flow—this constitutes the time-difference flow me asurement method. Here, the arrival time difference of the direct waves is directly proportional to the flow v elocity of the water layer along the direct acoustic path between the sensors. Unlike traditional time-differe nce methods, this approach employs self-organizing wireless data links for communication between the lef t and right banks, with dual units synchronized via satellite timing. Moreover, the installation in the river ch annel does not impede navigation, offering an efficient and convenient solution for river flow monitoring.
