Prerequisites for Installation
Optimal Piping Conditions
For optimal performance, the installation of the vortex flowmeter necessitates a specific straight pipe section both upstream and downstream. The common configurations are as follows (D represents the pipe's diameter):
1.
Install the sensor on a horizontal, vertical, or inclined pipe (with liquid flowing upward) that matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream from the sensor.
2.
The pipe near the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
Maintain uniformity between the inner diameter of the straight pipe section and the sensor diameter. If mismatched, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Avoid installation in areas with strong electromagnetic interference, confined spaces, or where maintenance is challenging..
5.
Horizontal pipeline installation is most common. For gas flow 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, the sensor can be installed regardless of flow direction. For gas flow with minor liquid content, ensure upward flow. For liquid flow, ensure upward flow to prevent added weight on the probe.
7.
Side-mounting on horizontal pipelines is suitable for all fluids, particularly superheated steam, saturated steam, and low-temperature liquids. Side-mounting, when feasible, is preferable to reduce temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. 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 necessary.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
Pressure and temperature measurement points should be strategically chosen. The pressure measurement point must be 3-5D downstream, and the temperature measurement point 6-8D downstream of the sensor.
