Installation Requirements
Piping Condition
The installation of the Vortex Flowmeter requires a specific length of straight pipe both before and after the device. The common scenarios are as follows (D represents the pipe diameter):
1.
The sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the sensor's diameter. Ensure the straight pipe upstream is 15-20D and downstream is 5-10D.
2.
The pipe near the liquid sensor must be completely filled with the measured liquid.
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's diameter. If not identical, a slightly larger pipe is acceptable with an error ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common method. For gas flow with minor liquid content, position the sensor higher in the pipeline. For liquid flow with minor gas content, place the sensor lower in the pipeline.
6.
Vertical pipeline installation: For gas flow, the sensor can be installed without flow direction restrictions. If the gas contains liquid, the flow should be from bottom to top. For liquid flow, position the sensor to ensure the flow is from bottom to top to reduce probe weight impact.
7.
Side installation on horizontal pipelines: Suitable for various fluids, particularly superheated steam, saturated steam, and cold liquids. Prefer side mounting to minimize temperature effects on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can measure saturated steam and high-temperature liquids or when frequent pipeline cleaning is required.
9.
For pipelines with insulation layers measuring high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points: Depending on the requirements, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
