Ultrasonic flow meter designed for open water channels. Capable of measuring average flow velocity with high precision.
The DX&PX series can measure average flow velocity with high precision. Ultrasonic waves are emitted at a certain angle from a detector installed in the waterway. Immediately afterward, it switches to receiving mode and captures the ultrasonic waves reflected by suspended particles (impurities and bubbles) in the fluid. This is visualized and stored as the first scan after digital processing. Similarly, emission and reception are performed, and the flow velocity is analyzed based on the movement distance of suspended particles compared to the first scan. This is stored as the second scan, just like the first scan. Additionally, the flow velocity distribution, which changes with water depth, is measured intermittently by dividing it into windows. By repeating this operation up to 2000 times per second, the average flow velocity is measured in real-time with high precision.

basic information
Main Features ■ It allows for easy measurement of open channels that are difficult to measure. ■ It does not require construction of channels like traditional weir or flume types. ■ It supports symmetrically shaped open channels, and if linked with a water level sensor, flow measurement is also possible. Usage Conditions ■ The cables for the converter and detector can be extended up to 350 meters using dedicated cables. ■ Water level gauges that can output 4-20 mADC types can be connected. ■ Flow measurement cannot be displayed unless the channel shape is symmetrical. *For other specifications, please request materials or view them via "Download."

| OCM Pro CF | The OCM Pro CF is an ultrasonic flow meter designed for open channels (non-full flow). It installs flow velocity sensors and water level sensors in a symmetrical channel and connects them to the flow meter converter. Inside the flow meter converter, the shape, width, and height of the channel are set to calculate the cross-sectional area by combining it with the water level. It receives signals from the flow velocity sensor installed in the channel, calculates the flow rate by multiplying it with the cross-sectional area, and displays/outputs the result. |
