Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific straight pipe section both before and after the meter. The standard requirements are as follows (D represents the diameter of the pipe):
1.
The sensor must be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) of the same diameter as the sensor. Ensure there are straight pipe sections of 15-20D upstream and 5-10D downstream of the sensor to meet proper installation requirements.
2.
The pipe adjacent to the liquid sensor must be fully filled with the measured liquid.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor's diameter. If an exact match isn't possible, opt for a slightly larger diameter with an error margin of ≤3% and not exceeding 5mm. The sensor should be free from areas with strong electromagnetic interference, restricted space, or challenging maintenance conditions..
5.
Horizontal pipeline installation is the most prevalent method for flow sensors. For gas flow measurements with minor liquid content, position the sensor at the pipeline's highest point. For liquid flow with minor gas content, the sensor should be installed at the lowest point in the pipeline.
6.
Vertical pipeline sensor installation. For gas flow, the sensor can be placed on a vertical pipe without flow direction constraints. If the gas contains some liquid, flow should be from bottom to top. For liquid flow, ensure it is from bottom to top to minimize additional weight on the probe.
7.
Side-mounted sensor installation on horizontal pipelines. Sensors can be side-mounted regardless of the fluid type, especially effective for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when conditions allow, 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 for pipelines requiring frequent cleaning.
9.
When installing sensors on insulated pipelines, ensure the insulation layer is no more than one-third of the bracket height for high-temperature steam measurements.
10.
Selecting pressure and temperature measurement points. Based on measurement needs, pressure should be measured 3-5D downstream of the sensor and temperature 6-8D downstream of the sensor to ensure accurate readings.
