Installation Requirements
Piping condition
The installation of vortex flowmeter requires a certain straight pipe section before and after, and the common situations are as follows (D is the diameter of the pipe):
1.
The sensor should be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and has the same diameter as the sensor. Ensure a certain length of straight pipe upstream and downstream of the sensor: 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
The pipe near the liquid sensor must be completely filled with the liquid being measured.
3.
The sensor should not be installed on a pipe with strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should match the sensor diameter as closely as possible. If they differ, use a slightly larger diameter pipe with an error ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, limited space, or where maintenance is inconvenient. Installation requirements.
5.
Horizontal pipeline installation is the most common method for flow sensors. When measuring gas flow, if the gas contains a small amount of liquid, place the sensor at a higher point in the pipeline. For liquid flow, if the liquid has a small amount of gas, install the sensor at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines. For gas flow, the sensor can be installed vertically without flow direction restrictions. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flow, ensure the flow is from bottom to top to avoid adding weight to the probe.
7.
Side installation of sensors on horizontal pipelines. Suitable for all fluids, including superheated steam, saturated steam, and low-temperature liquids. Side mounting minimizes temperature effects on the amplifier, making it preferable if conditions allow.
8.
Inverted installation of sensors on horizontal pipelines. Generally not recommended for general gases or superheated steam, but can be used for saturated steam and high-temperature liquids or when frequent pipeline cleaning is required.
9.
Installation of sensors on pipelines with insulation layers. When measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points. For accuracy, place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream of the sensor.
