Installation Requirements
Piping condition
Ensuring optimal performance with our vortex flowmeter necessitates a straight pipe section both upstream and downstream. The standard configurations are as follows (D represents the pipe's diameter):
1.
Install the sensor on a pipe that is horizontal, vertical, or inclined (with liquid flowing from bottom to top). Ensure the pipe diameter matches the sensor's. Provide a straight pipe length of 15-20D upstream and 5-10D downstream.
2.
Ensure the pipe adjacent to the liquid sensor is filled with the liquid being measured.
3.
Avoid placing the sensor on pipes experiencing strong mechanical vibrations.
4.
Maintain consistency between the inner diameter of the straight pipe section and the sensor diameter. If a match isn't possible, use a slightly larger pipe with an error margin of ≤3% and not more than 5mm. Avoid areas with strong electromagnetic interference, limited space, or difficult maintenance..
5.
Horizontal pipeline installation is common. For gas flow with minor liquid content, install the sensor at a higher pipeline point. For liquid flow with minor gas content, place the sensor at a lower point.
6.
Vertical pipeline sensor installation. For gas flow, install on vertical pipelines without flow direction restrictions. If the gas has minor liquid content, position the flow from bottom to top. For liquid flow, position from bottom to top to avoid extra weight on the probe.
7.
Side installation of sensors on horizontal pipelines is versatile, especially for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible, as it minimizes temperature effects on the amplifier.
8.
Inverted 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, especially where pipelines require frequent cleaning.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation doesn't exceed one-third of the bracket height.
10.
Pressure and temperature measurement points selection. Depending on measurement needs, place the pressure point 3-5D downstream and the temperature point 6-8D downstream of the sensor.
