Detailed Installation Requirements for Seamless Integration
Piping Condition: Ensuring Optimal Flow Conditions
For precise installation of the vortex flowmeter, it is crucial to maintain a specific length of straight pipe both before and after the device. The typical configurations are as follows (D represents the pipe's diameter):
1.
Ensure that the sensor is mounted on a horizontal, vertical, or inclined pipe (with the liquid flowing upwards) that matches the sensor's diameter. The upstream straight pipe should be 15-20D long, and the downstream section should be 5-10D to ensure accurate readings.
2.
The pipe surrounding the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations to maintain accuracy.
4.
The inner diameter of the straight pipe should closely match the sensor's diameter. If they differ, opt for a slightly larger pipe with a deviation of ≤3% and no more than 5mm. Avoid installing sensors in areas with significant electromagnetic interference, restricted space, or where maintenance is challenging..
5.
Horizontal pipeline installation is most common. For gas flow with minor liquid content, place the sensor at a higher point. For liquid flow with minor gas content, install the sensor at a lower point.
6.
Vertical pipeline sensor installation: For gas flow, install the sensor on a vertical pipeline without flow direction restrictions. If the gas contains some liquid, ensure upward flow. For liquid flow, direct the flow from bottom to top to minimize probe weight.
7.
Side-mounting sensors on horizontal pipelines is ideal for fluids, especially superheated steam, saturated steam, and low-temperature liquids. Side installation is recommended when possible as it reduces the 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, especially in conditions requiring frequent pipeline cleaning.
9.
When measuring high-temperature steam with insulated pipelines, ensure the insulation layer does not exceed one-third of the bracket height.
10.
For pressure and temperature measurements near the sensor, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream to ensure precise readings.
