Installation
Integral Display Flange Ultrasonic Flow Meter Installation Requirement
Generally, the following principles should be followed:
- To select a pipe section filled with fluid, such as a vertical part of the pipeline or a horizontal pipe section filled with fluid.
- The measuring point should be 10 times the diameter from the upstream and the straight pipe section within 5 times the diameter from the downstream, and the distance from the valve outlet should be as far as possible.
- Ensure the temperature at the measuring point is within the working range.
- Fully consider the fouling condition of the inner wall of the pipe, and try to select a non-scaling pipe section for measurement. When it cannot be satisfied, fouling should be considered as a lining for better measurement accuracy.
- Select pipe sections with uniform and dense pipes that are easy for ultrasonic transmission.
- Please refer to the two examples on the right for the selection of measuring points.
