Installation Requirements
Piping condition
The installation of the vortex flowmeter requires a specific straight pipe section before and after the device. The standard configurations are as follows (D is the pipe diameter):
1.
The sensor should be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the diameter of the sensor. Ensure a straight pipe section upstream and downstream of the sensor. The upstream section should be 15-20D, and the downstream should be 5-10D.
2.
The pipe near the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes with strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should match the sensor diameter closely. If matching is not possible, use a slightly larger pipe with an error of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, limited space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common method. For gas flow, if the gas contains a small amount of liquid, install the sensor at a higher point in the pipeline. For liquid flow, if the liquid contains a small amount of gas, install the sensor at a lower point.
6.
Vertical pipeline installation. For gas flow, the sensor can be installed on a vertical pipeline without flow direction restriction. If the gas contains a small amount of liquid, flow should be bottom to top. For liquid flow, ensure the flow is from bottom to top to avoid additional weight on the probe.
7.
Side installation on horizontal pipelines. Regardless of the fluid type, sensors can be side-mounted on horizontal pipelines. This method is preferred for superheated steam, saturated steam, and low-temperature liquids as it minimizes the temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. It is unsuitable for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids or situations requiring frequent pipeline cleaning.
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.
Selecting pressure and temperature measurement points. For accurate measurements, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.
