Multi-parameter water quality analyzer
This flowmeter is based on the transit-time measurement principle and features an open-structure design, making it ideal for precise flow measurement in main and branch channels of water conservancy and irrigation systems.
It integrates an ultrasonic velocity measurement unit and a radar water level unit to accurately measure water flow through layered velocity and water level data.
The device can be easily connected to RTUs, lithium batteries, solar chargers, and other equipment to enable data storage and real-time transmission of water level and flow information.
It offers high measurement accuracy, excellent reliability, and simple maintenance.
Open-channel and sluice gate flow measurement and monitoring for water conservancy, agriculture, and irrigation systems.
Flow measurement and monitoring for urban drainage systems.
