Installation Requirements
Piping Condition
The installation of the vortex flowmeter requires specific straight pipe sections before and after to ensure optimum performance. The common specifications are as follows (where D is the diameter of the pipe):
1.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a straight pipe section upstream of 15-20D and downstream of 5-10D to meet operational standards.
2.
The pipe near the liquid sensor must be filled with the liquid being measured to ensure accurate readings.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations to maintain measurement accuracy.
4.
The inner diameter of the straight pipe section should match the sensor diameter as closely as possible. If they differ, use a slightly larger pipe with an error ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurement with minor liquid content, place the sensor at a higher pipeline point. For liquid flow with minor gas content, install the sensor at a lower pipeline point.
6.
For vertical pipelines, sensors measuring gas flow can be installed without flow direction restrictions. If the gas contains minor liquid, the flow should be from bottom to top. For liquid flow, ensure it moves from bottom to top to prevent additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines is versatile, suitable for all fluids, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred to minimize temperature impact on the amplifier, if conditions allow.
8.
Inverted installation of sensors on horizontal pipelines is generally discouraged, except for measuring saturated steam or high-temperature liquids. It is suitable when frequent pipeline cleaning is required.
9.
When installing sensors on insulated pipelines, ensure the insulation layer does not exceed one-third of the bracket height for accurate high-temperature steam measurements.
10.
For precise pressure and temperature readings, position the pressure measurement point 3-5D downstream, and the temperature measurement point 6-8D downstream of the sensor, based on measurement requirements.
