Detailed Installation Requirements
Piping Condition Specifications
To ensure optimal performance, the vortex flowmeter must be installed with specific straight pipe sections both upstream and downstream. The standard configurations are: (D represents the diameter of the pipe):
1.
The sensor must be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing upward) that matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe surrounding the liquid sensor must always be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor's diameter. If an exact match isn't possible, use a slightly larger pipe with a deviation of ≤3% and no more than 5mm. Avoid locations with significant electromagnetic interference, limited space, or poor access for maintenance..
5.
Horizontal pipeline installations are most common for flow sensors. For gas flows containing small amounts of liquid, install the sensor at the highest point. For liquid flows containing small amounts of gas, install the sensor at the pipeline's lowest point.
6.
Vertical installation for gas flows is straightforward, with no direction restrictions. If gas contains liquid, ensure flow is from bottom to top. For liquid flows, position the sensor so that flow rises from bottom to top, preventing additional weight on the probe.
7.
Side-mounted sensors on horizontal pipelines are effective for measuring superheated steam, saturated steam, and low-temp liquids. This preferred method minimizes temperature effects on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged but can be used for saturated steam and high-temperature liquids or when frequent pipeline cleaning is necessary.
9.
For pipelines with insulation layers measuring high-temp steam, the insulation should cover no more than one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Position pressure sensors 3-5D downstream, and temperature sensors 6-8D downstream of the primary sensor, based on the required measurements.
