Pre-Installation Requirements
Optimal Piping Conditions
For optimal performance, a certain length of straight pipe is required before and after the installation of the vortex flowmeter. Typical requirements are as follows (D represents the diameter of the pipe):
1.
Ensure that the sensor is mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. A straight length of pipe is necessary both upstream and downstream of the sensor, with 15-20D for the front section and 5-10D for the rear section.
2.
The pipe close to the liquid sensor must be fully filled with the liquid to be measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the pipe section should closely match the sensor diameter. If not identical, opt for a slightly larger diameter pipe with a deviation of ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, constrained spaces, or where maintenance is challenging..
5.
Horizontal pipeline installation is the standard method for flow sensors. For gas flow containing minimal liquid, position the sensor at the higher point of the pipe. For liquid flow containing minimal gas, position the sensor at the lower point of the pipe.
6.
Vertical pipeline installation is applicable for gas flow measurement without flow direction constraints. For gas containing minimal liquid, ensure the flow is from bottom to top. For liquid flow, ensure the direction is from bottom to top to prevent additional weight on the sensor probe.
7.
For horizontal pipelines, side-mount sensors are suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to reduce temperature impacts on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged and unsuitable for general gases or superheated steam. However, it can be used for saturated steam or high-temperature liquids, especially where frequent pipe cleaning is necessary.
9.
When measuring high-temperature steam, ensure that the insulation layer on the pipeline does not exceed one-third of the bracket height.
10.
For accurate pressure and temperature measurements near the sensor, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
