Mandatory Installation Requirements
Optimal Piping Conditions
For optimal performance, the installation of the vortex flowmeter necessitates specific straight pipe sections both upstream and downstream. The common requirements are as follows (where D represents the diameter of the pipe):
1.
Ensure the sensor is mounted on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the diameter of the sensor. The straight pipe length should meet the requirement: 15-20D upstream and 5-10D downstream.
2.
The section of the pipe near the liquid sensor must be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should be as close as possible to the sensor diameter. If they must differ, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Additionally, avoid areas with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common. For gas flow measurement with a small amount of liquid, install the sensor at a higher point in the pipeline. For liquid flow with a small amount of gas, install the sensor at a lower point in the pipeline.
6.
For vertical pipeline installation: When measuring gas flow, the sensor can be mounted on a vertical pipeline without flow direction constraints. If the gas contains a small amount of liquid, ensure the gas flows from bottom to top. For liquid flow, ensure the liquid flows from bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is suitable for any fluid, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred to reduce temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not advised. It is unsuitable for general gases or superheated steam but may be used for saturated steam and high-temperature liquids, or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, when measuring high-temperature steam, the insulation layer must not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: For accurate measurements, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
