Installation Requirements
Piping Condition
The installation of a vortex flowmeter necessitates specific straight pipe sections both upstream and downstream for optimal performance. Common configurations are detailed below (D represents the pipe's diameter):
1.
The sensor should be mounted on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top) and matches the sensor's diameter. Ensure an appropriate length of straight pipe: 15-20D upstream and 5-10D downstream.
2.
The pipe adjacent to the liquid sensor must be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should ideally match the sensor's diameter. If not possible, use a slightly larger diameter pipe with an error margin of ≤3% (not exceeding 5mm). Avoid installation in areas with strong electromagnetic interference, restricted space, or inconvenient maintenance..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow containing minor liquids, place the sensor at the pipeline's higher point. For liquid flow containing minor gases, place the sensor at the pipeline's lower point.
6.
Vertical pipeline sensor installation. For gas flow, the sensor can be installed on a vertical pipeline without direction constraints. If the gas contains minor liquids, flow must be from bottom to top. For liquid flow, ensure flow is from bottom to top to minimize probe weight.
7.
Side-mounting sensors on horizontal pipelines is viable for any fluid, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferable when conditions allow, minimizing temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It's unsuitable for general gases or superheated steam but can measure saturated steam and high-temperature liquids, or in scenarios requiring frequent pipeline cleaning.
9.
For sensors on insulated pipelines measuring high-temperature steam, ensure the insulation layer does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points. Based on measurement needs, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream.
