Installation Requirements
Piping Condition
For optimal performance, the installation of the Anti Vibration Vortex Flowmeter requires specific straight pipe sections both before and after the meter. The common guidelines are detailed below (D represents the diameter of the pipe):
1.
The sensor should be installed on a pipe that is either horizontal, vertical, or inclined (with the liquid flowing from bottom to top). The pipe must match the sensor's diameter. Ensure there's a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor.
2.
Ensure that the pipe near the liquid sensor is filled with the liquid being measured to maintain accuracy.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations, as this can affect performance.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If an exact match isn't possible, use a slightly larger pipe with an error margin of ≤3% and no more than 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, limited space, or where maintenance is difficult..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flows containing small amounts of liquid, install the sensor at a higher point in the pipeline. For liquid flows containing small amounts of gas, install the sensor at a lower point.
6.
For vertical pipelines, when measuring gas flow, the sensor can be installed without flow direction restrictions. If the gas contains a small amount of liquid, the flow should be from bottom to top. For liquid flows, ensure the flow is also from bottom to top to prevent additional weight on the probe.
7.
Side mounting on horizontal pipelines is suitable for all fluid types. This method is particularly recommended for superheated steam, saturated steam, and low-temperature liquids as it minimizes temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended. It’s unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, or in situations requiring frequent pipeline cleaning.
9.
When measuring high-temperature steam, ensure the insulation layer on the pipeline does not exceed one-third of the bracket height to maintain measurement accuracy.
10.
For accurate pressure and temperature measurements near the sensor, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream.
