Installation Requirements
Piping Condition
For optimal performance, installing the High Temperature Anti Vibration Vortex Flowmeter necessitates a specific arrangement of straight pipe sections both upstream and downstream. The general guidelines are as follows (where D represents the pipe's diameter):
1.
Ensure the sensor is positioned on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Sufficient lengths of straight pipe must be present: 15-20D upstream and 5-10D downstream.
2.
The pipe adjacent to the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If a perfect match isn't possible, opt for a slightly larger diameter with an error margin of ≤3% and not exceeding 5mm. Do not install in areas with strong electromagnetic interference, limited access, or difficult maintenance..
5.
Horizontal pipeline installation is most common. For gas flow measurements where the gas contains small liquid amounts, place the sensor at the highest pipeline point. For liquid flow measurements with small gas amounts, position the sensor at the lowest point.
6.
Vertical pipeline sensor installation. For gas flow measurements, the sensor can be mounted on a vertical pipeline irrespective of the flow direction. If the gas includes small liquid amounts, the flow should be bottom to top. For liquid flow, it should always be bottom to top to minimize additional weight on the probe.
7.
Side-mounted sensor installation on horizontal pipelines is viable for all fluids, particularly superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred where possible to reduce the amplifier's temperature effects.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged, unsuitable for general gas or superheated steam measurements, but can be used for saturated steam, high-temperature liquids, or pipelines needing frequent cleaning.
9.
When insulating high-temperature steam pipelines, ensure the insulation does not exceed one-third of the bracket height.
10.
Pressure and temperature measurement points should be selected based on specific measurement needs. Position pressure measurement points 3-5D downstream of the sensor and temperature measurement points 6-8D downstream.
