Installation Requirements
Piping Condition
The installation of a vortex flowmeter necessitates a specific length of straight pipe section both upstream and downstream. The typical configurations are outlined below (D represents the diameter of the pipe):
1.
The sensor must be installed on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor diameter. Ensure there is a straight pipe section upstream (15-20D) and downstream (5-10D) of the sensor.
2.
The pipe adjacent to the sensor should be filled with the measured liquid.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If not, opt for a slightly larger pipe diameter, with an error margin of ≤3% and not exceeding 5mm. Install the sensor away from areas with strong electromagnetic interference, restricted spaces, or where maintenance is challenging..
5.
Horizontal pipeline installation is the most prevalent for flow sensors. For gas flow containing a small amount of liquid, place the sensor at a higher pipeline point. For liquid flow containing gas, install the sensor at a lower pipeline point.
6.
In vertical pipelines, install the sensor without flow direction restrictions for gas flow. If the gas contains liquid, ensure flow from bottom to top. For liquid flow, the direction should also be from bottom to top to avoid additional probe weight.
7.
For horizontal pipelines, side-mounting sensors is viable for all fluid types, including superheated steam, saturated steam, and low-temperature liquids. This method is preferred if conditions allow as it reduces the temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally not recommended. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or when frequent pipeline cleaning is necessary.
9.
When installing sensors on pipelines with insulation layers, ensure the insulation does not exceed one-third of the bracket height for high-temperature steam measurement.
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.
