Integrated Ultrasonic Open Channel Flowmeter
1.Precision Manufacturing: The measuring box is made through precision machining, ensuring accurate internal size parameters for reliable measurements.
2.No On-site Calibration Required: The flowmeter is factory-calibrated, eliminating the need for on-site calibration, which simplifies installation and use.
3.Independence from Ditch Parameters: The accuracy of the flowmeter is not influenced by the parameters of the ditch or channel, ensuring consistent performance in varying conditions.
4.Time Difference Method: The flowmeter uses the time difference method to calculate the medium velocity by measuring the time difference between forward and reverse ultrasonic wave propagation in the fluid.
5.Velocity-Area Measurement: The flowmeter calculates the instantaneous and accumulated flow rates using the velocity-area method, combining data from ultrasonic transducers and the electronic water gauge.
The OBCS-XYS type integrated ultrasonic open channel flowmeter is an innovative upgrade based on the box-type ultrasonic open channel flowmeter. The device integrates a solar power supply system, data transmission system, and flow accumulation system, all of which are embedded within the product, greatly facilitating on-site construction operations. The integrated box-type ultrasonic open channel flowmeter has a very wide application range and is suitable for measuring the flow in various rectangular, trapezoidal open channels, as well as culverts. It can continuously monitor the flow of fluids such as irrigation water in open channels, accurately measuring flow and providing strong technical support for the management and protection of water resources. This device can be installed in channels as a metering device and can also serve as a flow calibration tool for calibrating third-party equipment.
