Installation Requirements
Piping Condition
The installation of a vortex flowmeter necessitates a designated section of straight piping both before and after the meter. The typical configurations are as follows (D represents the diameter of the pipe):
1.
The sensor must be installed on a pipe that is horizontal, vertical, or inclined (with the liquid flowing from bottom to top) and matches the sensor's diameter. There should be a specified length of straight pipe upstream and downstream of the sensor. The front straight pipe section should range from 15-20D, while the rear should be 5-10D.
2.
The pipe near the liquid sensor must be filled with the liquid being measured.
3.
The sensor must not be installed on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If identical diameters are not possible, a slightly larger pipe should be used, with an allowable error of ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient. Adherence to installation requirements is crucial..
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, the sensor should be positioned at a higher point in the pipeline. When measuring liquid flow, if the liquid contains a small amount of gas, the sensor should be placed at a lower point in the pipeline.
6.
Sensor installation in vertical pipelines: When measuring gas flow, the sensor can be installed without any restriction on flow direction. If the gas contains a small amount of liquid, the gas flow should be from bottom to top. For liquid flow, the liquid should ascend to prevent additional weight on the probe.
7.
Side installation of sensors on horizontal pipelines: Regardless of the fluid being measured, sensors can be side-mounted. This method is especially suitable for superheated steam, saturated steam, and low-temperature liquids. If conditions permit, side mounting is preferred as it reduces the temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines: Generally not recommended. This method is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or when pipelines require frequent cleaning.
9.
Installation of sensors on pipelines with insulation: When dealing with 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 measurement requirements, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream of the sensor.
