Installation Requirements
Piping condition
The installation of vortex flowmeter requires a certain straight pipe section before and after, and the common situations are as follows (D is the diameter of the pipe) :
1.
The sensor should be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and has the same diameter as the sensor. Ensure there is a straight pipe section before and after the sensor, with lengths of 15-20D upstream and 5-10D downstream.
2.
The pipe near the liquid sensor should always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If it cannot be the same, use a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is most common for flow sensors. For gas flows with minor liquid presence, install the sensor at a higher point in the pipeline. For liquid flows with minor gas presence, install the sensor at a lower point.
6.
Vertical pipeline sensor installation. For gas flow, sensors can be installed without flow direction restrictions. If gas has minor liquid content, ensure gas flows from bottom to top. For liquid flow, ensure it moves from bottom to top to avoid extra weight on the probe.
7.
Side-mounted installation on horizontal pipelines is possible for all fluids, especially for superheated steam, saturated steam, and low-temperature liquids. Prefer side mounting when possible to minimize temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally not recommended. It is unsuitable for most gases and superheated steam but can be used for saturated steam and high-temperature liquids or in frequently cleaned pipelines.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Pressure should be measured 3-5D downstream of the sensor, and temperature 6-8D downstream, based on measurement requirements.
