Key Installation Requirements
Crucial Piping Conditions
To ensure optimal performance, installing the vortex flowmeter necessitates specific sections of straight pipe both upstream and downstream. The typical configurations are illustrated as follows (where D denotes the diameter of the pipe):
1.
The sensor must be mounted on a horizontal, vertical, or inclined pipe (with liquid ascending from the bottom) that matches the sensor's diameter. Upstream and downstream straight pipe lengths should be 15-20D and 5-10D, respectively, to meet installation standards.
2.
The pipe adjacent to the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations to ensure accurate readings.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If exact matching is impossible, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Avoid installation in areas with high electromagnetic interference, limited space, or difficult maintenance..
5.
Horizontal pipeline installation is predominant for flow sensors. For gas flow with minor liquid content, install the sensor at the pipeline’s highest point. For liquid flow containing minor gas content, the sensor should be at the lowest point.
6.
Vertical pipeline installation is suitable for gas flow sensors, with no direction restrictions. If the gas has minor liquid content, ensure the flow is from bottom to top. For liquid flow, the direction should be upward to minimize the probe's weight impact.
7.
Side-mounting sensors on horizontal pipelines is viable for all fluids, including superheated and saturated steam, and low-temperature liquids. Side installation is preferred when feasible to reduce temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or in pipelines requiring frequent cleaning.
9.
For pipelines with insulation layers, especially high-temperature steam pipes, ensure the insulation does not exceed one-third of the bracket height.
10.
Strategically select pressure and temperature measurement points. Position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream from the sensor to ensure accurate readings.
