Installation Requirements
Piping condition
The installation of the vortex flowmeter necessitates a specific straight pipe section both upstream and downstream. The typical configurations are as follows (D represents the diameter of the pipe):
1.
The sensor must be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the sensor's diameter. Ensure a defined length of straight pipe upstream and downstream: 15-20D for the front and 5-10D for the rear.
2.
The pipe adjacent to the liquid sensor should be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to significant mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor's diameter. If not feasible, use a slightly larger diameter pipe, ensuring an error margin of ≤3% and not exceeding 5mm. Avoid installation in areas with strong electromagnetic interference, limited space, or difficult maintenance..
5.
Horizontal pipeline installation is prevalent for flow sensors. When measuring gas flow with a small amount of liquid, install the sensor at a higher pipeline point. For liquid flow with some gas, position the sensor at a lower point in the pipeline.
6.
For vertical pipelines: When measuring gas flow, install the sensor on a vertical pipeline without considering the flow direction. If the gas contains some liquid, the flow should be from bottom to top. For liquid flow, ensure it moves from bottom to top to prevent extra weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is versatile for all fluids, especially superheated steam, saturated steam, and low-temperature liquids. When possible, prefer side mounting to reduce temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally inadvisable. It's unsuitable for general gases or superheated steam but can measure saturated steam and high-temperature liquids or where frequent pipeline cleaning is necessary.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, the insulation should not exceed one-third of the bracket's height.
10.
Selecting pressure and temperature measurement points: Based on measurement needs, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.
