Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates certain straight pipe sections both upstream and downstream. The common configurations are as follows (D is the pipe diameter):
1.
The sensor must be mounted on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the sensor’s diameter. Ensure a straight pipe length of 15-20D upstream and 5-10D downstream.
2.
Ensure the pipe near the liquid sensor is completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with strong mechanical vibrations.
4.
Maintain consistency between the inner diameter of the straight pipe section and the sensor diameter. If not possible, opt for a slightly larger pipe with an error margin ≤3% and not exceeding 5mm. Avoid areas with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is most common for flow sensors. For gas flow containing a small amount of liquid, position the sensor at a higher point. For liquid flow containing a small amount of gas, place the sensor at a lower point in the pipeline.
6.
For vertical pipeline installations, when measuring gas flow, install the sensor on a vertical pipeline irrespective of the flow direction. If the gas contains liquid, ensure the gas flows from bottom to top. For liquid flow, ensure the flow is from bottom to top to avoid additional weight on the probe.
7.
For side installations on horizontal pipelines, sensors can be side-mounted regardless of the fluid. This is particularly advantageous for superheated steam, saturated steam, and low-temperature liquids, minimizing temperature impact on the amplifier.
8.
Inverted sensor installations on horizontal pipelines are generally discouraged. They are unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or where frequent pipeline cleaning is necessary.
9.
For pipelines with insulation layers, when measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
For pressure and temperature measurement points, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream, based on measurement requirements.
