Installation Requirements
Piping Condition
The installation of the vortex flowmeter requires specific straight pipe sections before and after the sensor. 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, meeting the requirements of 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
The pipe near the liquid sensor should be fully filled with the liquid being measured.
3.
The sensor should not be installed on a pipe experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If not possible, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, limited space, or where maintenance is inconvenient..
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, install the sensor at a higher point in the pipeline. For liquid flow measurement, if the liquid contains 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 on a vertical pipeline with no flow direction restriction. If the gas contains a small amount of liquid, the gas flow should be from bottom to top. For liquid flow, the liquid should flow from bottom to top to avoid additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines. Sensors can be side-mounted on horizontal pipelines, especially when measuring superheated steam, saturated steam, or low-temperature liquids. Side mounting is preferred if conditions allow as it minimizes the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended. It is unsuitable for measuring general gases or superheated steam but can be used for measuring saturated steam and high-temperature liquids or in situations requiring frequent pipeline cleaning.
9.
Installation of sensors on pipelines with insulation layers. When measuring high-temperature steam, the insulation layer should not exceed one-third of the bracket height.
10.
Selection of pressure and temperature measurement points. Depending on the measurement requirements, when pressure and temperature need to be measured near the sensor, place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream of the sensor.
