Installation Requirements
Piping Condition
To ensure optimal performance, the installation of the vortex flowmeter necessitates a certain length of straight pipe both upstream and downstream. The typical scenarios include (D represents the diameter of the pipe):
1.
For precise measurements, the sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with the liquid ascending). The pipe's diameter must match that of the sensor. Additionally, ensure the presence of a straight pipe segment upstream (15-20D) and downstream (5-10D) to maintain accuracy.
2.
Ensure the pipe near the sensor is filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match that of the sensor. If not, a pipe with a slightly larger diameter (≤3%, not exceeding 5mm) is acceptable. Avoid locations with strong electromagnetic interference, restricted space, or difficult maintenance conditions..
5.
Horizontal pipeline installation is most typical for flow sensors. When measuring gas that contains traces of liquid, position the sensor at a higher point on the pipeline. Conversely, when measuring liquid with traces of gas, install the sensor at a lower point.
6.
Vertical pipeline sensor installation is versatile. For gas flow measurement, the sensor can be mounted in any direction. If the gas contains liquid, ensure the flow is from bottom to top. For liquid flow, positioning it from bottom to top minimizes the probe's additional weight.
7.
For horizontal pipelines, side-mounting sensors is ideal regardless of the fluid type. This method is particularly recommended for superheated steam, saturated steam, and low-temperature liquids as it reduces the amplifier's exposure to temperature variations.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially when frequent pipeline cleaning is necessary.
9.
When measuring high-temperature steam, ensure the insulation layer's thickness does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Position the pressure measurement point 3-5D downstream from the sensor, and the temperature measurement point 6-8D downstream, based on the measurement requirements.
