Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe both upstream and downstream for optimal performance. The common scenarios are as follows (D denotes the diameter of the pipe):
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing upwards in the inclined position) that matches the sensor’s diameter. Ensure the pipe has a straight section of 15-20D upstream and 5-10D downstream of the sensor, meeting the required lengths.
2.
Ensure the pipe near the liquid sensor is completely filled with the liquid to be measured.
3.
Do not install the sensor on pipes subject to significant mechanical vibrations.
4.
The straight pipe's inner diameter should closely match the sensor's diameter. If not, use a slightly larger pipe with an error margin ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with severe electromagnetic interference, restricted space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most conventional method for flow sensors. For gas flow with some liquid content, install the sensor at a higher point in the pipeline. For liquid flow with some gas content, install the sensor at a lower point in the pipeline.
6.
For vertical pipeline installation: When measuring gas flow, the sensor can be installed without flow direction constraints. If the gas contains liquid, ensure the flow is from bottom to top. For liquid flow, always install the sensor with the flow from bottom to top to prevent additional probe weight.
7.
Horizontal pipeline side installation: This method is suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting reduces temperature impact on the amplifier and is preferred whenever feasible.
8.
Inverted horizontal pipeline installation is generally discouraged. It is unsuitable for general gases or superheated steam but may be used for saturated steam and high-temperature liquids, particularly where frequent pipeline cleaning is necessary.
9.
For pipelines with insulation layers 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 placed: the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor, in accordance with measurement requirements.
