Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe sections both upstream and downstream, with the standard configurations as follows (D is the pipe diameter):
1.
The sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and is of the same diameter as the sensor. Ensure there is a straight pipe section upstream and downstream, meeting the length requirements of 15-20D for the front section and 5-10D for the rear section.
2.
The pipe close to the liquid sensor must always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience significant mechanical vibrations.
4.
The internal diameter of the straight pipe section should closely match the sensor diameter. If they vary, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, confined spaces, or where maintenance is difficult. Installation requirements..
5.
Horizontal pipeline installation is the most typical approach for flow sensors. For gas flow measurement, if the gas contains a small amount of liquid, place the sensor at a higher point in the pipeline. For liquid flow measurement, if the liquid contains a small amount of gas, position the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation for gas flow measurement allows mounting without flow direction restrictions. If the gas contains liquid, ensure the flow is from bottom to top. For liquid flow, install the sensor with the flow from bottom to top to avoid additional weight on the probe.
7.
Side mounting of sensors on horizontal pipelines is permissible for any fluid type, especially advantageous for superheated steam, saturated steam, and low-temperature liquids. Side mounting is often preferred as it reduces temperature impacts on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is not generally recommended, particularly for general gases or superheated steam. It is suitable for saturated steam, high-temperature liquids, or pipelines that require frequent cleaning.
9.
For pipelines with insulation layers, especially when measuring high-temperature steam, the insulation layer should cover no more than one-third of the bracket height.
10.
Pressure and temperature measurement points should be selected based on measurement needs. The pressure measurement point should be 3-5D downstream of the sensor, while the temperature measurement point should be 6-8D downstream.
