Installation Requirements
Piping condition
The installation of a vortex flowmeter necessitates a specific straight pipe section both upstream and downstream. Typical configurations are as follows (D signifies the pipe's diameter):
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) of the same diameter as the sensor. It’s crucial to have a straight pipe of a specified length upstream (15-20D) and downstream (5-10D) of the sensor.
2.
The pipe adjacent to the liquid sensor must be filled with the liquid being measured.
3.
Ensure the sensor is not placed on pipes subjected to strong mechanical vibrations.
4.
The straight pipe section's inner diameter should ideally match the sensor diameter. If not, use a slightly larger pipe with a deviation of ≤3% and no more than 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is challenging. Installation requirements.
5.
Horizontal pipeline installation is the most prevalent for flow sensors. For gas flow measurement when a small amount of liquid is present, the sensor should be at a higher pipeline point. For liquid flow containing some gas, install the sensor at a lower pipeline point.
6.
In vertical pipelines, the sensor can be installed without flow direction restrictions for gas flow measurement. If the gas has a small liquid amount, ensure the flow is bottom-to-top. Similarly, for liquid flow, the movement should be bottom-to-top to prevent extra weight on the probe.
7.
Sensors can be side-mounted on horizontal pipelines for any fluid, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred to diminish temperature effects on the amplifier, if feasible.
8.
Inverted sensor installation on horizontal pipelines is generally inadvisable. It’s unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, or when frequent pipeline cleaning is needed.
9.
When measuring high-temperature steam with pipeline insulation, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: For measurements near the sensor, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
