Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe section both upstream and downstream. The common scenarios are detailed as follows (D represents the diameter of the pipe):
1.
The sensor must be mounted on a horizontal, vertical, or inclined pipe (with the liquid flowing bottom to top) and should match the sensor's diameter. A precise length of straight pipe is essential: 15-20D upstream and 5-10D downstream.
2.
Ensure that the pipe near the liquid sensor is completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
The inner diameter of straight pipe sections should closely match the sensor's diameter. If an exact match is impossible, a slightly larger diameter with an error margin of ≤3% and not exceeding 5mm is acceptable. Avoid locations with strong electromagnetic interference, restricted spaces, or challenging maintenance..
5.
Horizontal pipeline installation is the most prevalent method. For gas flow with minor liquid content, position the sensor at a higher pipeline point. For liquid flow with minor gas content, install the sensor at a lower point.
6.
In vertical pipelines for gas flow, the sensor can be placed without directional restrictions. For gas with minor liquid content, ensure the flow direction is bottom to top. For liquid flow, direct the flow from bottom to top to prevent additional weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is viable for all fluids, particularly superheated steam, saturated steam, and low-temperature liquids. This method is recommended if conditions permit, as it reduces temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally inadvisable for most gases and superheated steam but can be used for saturated steam and high-temperature liquids or where frequent pipeline cleaning is necessary.
9.
For high-temperature steam measurements with insulated pipelines, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: When necessary, place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream.
