Installation Requirements
Piping Condition
The installation of a vortex flowmeter necessitates a specific straight pipe section before and after the device. The common configurations are as follows (D denotes the diameter of the pipe):
1.
The sensor must be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure sufficient lengths of straight pipe on both sides of the sensor: 15-20D upstream and 5-10D downstream.
2.
Ensure the pipe near the liquid sensor is entirely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience significant mechanical vibrations.
4.
The inner diameter of the straight pipe section should align closely with the sensor diameter. If discrepancies arise, use a slightly larger pipe (error margin ≤3%, not exceeding 5mm). Avoid areas with strong electromagnetic interference, confined spaces, or where maintenance is cumbersome..
5.
Horizontal pipeline installation is the prevalent method for flow sensors. When measuring gas flow with minor liquid content, position the sensor at the pipeline's higher point. For liquid flow with minor gas content, position the sensor at the lower point.
6.
Vertical pipeline sensor installation: For gas flow, install the sensor vertically without flow direction constraints. If the gas contains minor liquid, ensure the flow is from bottom to top. For liquid flow, ensure the flow ascends to avoid adding weight to the probe.
7.
Side installation on horizontal pipelines: Suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred as it reduces temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuited for general gases or superheated steam but can measure saturated steam and high-temperature liquids, especially when frequent pipeline cleaning is required.
9.
For high-temperature steam, the insulation layer should not exceed one-third of the bracket height.
10.
Pressure and temperature measurement points: Position the pressure measurement point 3-5D downstream, and the temperature measurement point 6-8D downstream of the sensor.
