Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates specific straight pipe sections before and after the device. The standard requirements are as follows (D represents the diameter of the pipe):
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 sufficient straight pipe lengths upstream and downstream of the sensor, adhering to 15-20D for the front and 5-10D for the rear.
2.
The pipe adjacent to the liquid sensor must be filled with the measured liquid.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe should ideally match the sensor’s diameter. If not possible, use a slightly larger diameter with a deviation of ≤3% and not exceeding 5mm. Avoid placing the sensor in areas with strong electromagnetic interference, limited space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flows containing a small amount of liquid, position the sensor at a higher point in the pipeline. For liquid flows with minimal gas, install the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation. For gas flow measurements, the sensor can be installed on a vertical pipeline without flow direction restrictions. If the gas contains some liquid, the flow direction should be from bottom to top. For liquid flow, the direction should also be from bottom to top to avoid extra weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is acceptable for all fluid types, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible as it minimizes temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It is unsuitable for measuring most gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially where pipelines require frequent cleaning.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points: When these parameters need measuring near the sensor, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.
