Installation Requirements
Piping Condition
Installing the vortex flowmeter necessitates specific straight pipe sections before and after the device. Here are the common scenarios (D is the pipe's diameter):
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a straight pipe length of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe near the liquid sensor must be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes experiencing strong mechanical vibrations.
4.
Ensure the inner diameter of the straight pipe section closely matches the sensor diameter. If not possible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Avoid installations in areas with strong electromagnetic interference, limited space, or difficult maintenance. Installation requirements:.
5.
For horizontal pipelines, the most common installation method: When measuring gas flow that contains a small amount of liquid, place the sensor at a higher point. For liquid flow with a small amount of gas, install the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation: For gas flow, the sensor can be placed on a vertical pipeline without a flow direction restriction. If the gas contains a small amount of liquid, ensure the gas flows from bottom to top. For liquid flow, it should be from bottom to top to avoid adding weight to the probe.
7.
Side-mounting sensors on horizontal pipelines: This method is suitable for any fluid, particularly superheated steam, saturated steam, and low-temperature liquids. This installation type minimizes temperature impacts on the amplifier and is preferred if conditions allow.
8.
Inverted sensor 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, especially where frequent pipeline cleaning is required.
9.
For pipelines with insulation layers measuring high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Based on measurement needs, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream of the sensor.
