Installation Requirements
Piping Condition
To ensure optimal performance of the vortex flowmeter, it is essential to maintain specific straight pipe sections before and after the installation. The typical configurations are as follows (where 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) that matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream.
2.
The pipeline adjacent to the liquid sensor should be filled with the liquid being measured.
3.
Avoid installing the sensor on pipelines subject to strong mechanical vibrations.
4.
Ensure the inner diameter of the straight pipe section is as consistent as possible with the sensor diameter. If it differs, opt for a slightly larger pipe with an error of ≤3% and no more than 5mm. Avoid areas with strong electromagnetic interference, limited space, or difficult maintenance..
5.
Horizontal pipeline installation is prevalent for flow sensors. For gas flow measurements with small liquid content, place the sensor at a higher point. For liquid flow with small gas content, position the sensor at a lower point.
6.
For vertical pipeline installations, the sensor can measure gas flow in any direction. If the gas contains some liquid, ensure the flow is from bottom to top. For liquid flow, always have the flow from bottom to top to prevent additional weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is effective for superheated steam, saturated steam, and low-temperature liquids. Side installation is preferable where feasible, as it reduces temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged, except for measuring saturated steam or high-temperature liquids, or when frequent cleaning is required.
9.
When measuring high-temperature steam, 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 of the sensor.
