Installation Requirements
Piping condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe sections both upstream and downstream. The common configurations are as follows (D represents the diameter of the pipe):
1.
The sensor must be mounted on a pipe that can be horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor's diameter. Ensure the straight pipe length meets 15-20D upstream and 5-10D downstream requirements.
2.
The pipe around the liquid sensor should be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with significant mechanical vibrations.
4.
The straight pipe section's inner diameter should closely match the sensor's diameter. If not possible, use a slightly larger diameter pipe, within an error of ≤3% and not exceeding 5mm. The sensor should not be placed where there's strong electromagnetic interference, restricted space, or difficult maintenance..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow with a small amount of liquid, install the sensor at the pipeline's higher point. For liquid flow with a small amount of gas, install it at the lower point.
6.
Vertical pipeline sensor installation. For gas flow, the sensor can be installed on a vertical pipeline with any flow direction. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flow, it should be from bottom to top to avoid extra weight on the probe.
7.
Side installation of sensors on horizontal pipelines. Suitable for any fluid, side mounting is ideal for superheated steam, saturated steam, and low-temperature liquids, as it reduces temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally avoided. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially where frequent pipeline cleaning is needed.
9.
For insulated pipelines with high-temperature steam, ensure the insulation layer is no thicker than one-third of the bracket height.
10.
Choosing pressure and temperature measurement points: For precise measurements near the sensor, place the pressure point 3-5D downstream and the temperature point 6-8D downstream.
