Installation Requirements
Piping Condition
The installation of the Steam Vortex Flowmeter with Wear Resistant and Low Pressure Loss from Shandong Zhongziyi Intelligent Technology Co., Ltd. requires specific straight pipe sections before and after the meter. The common requirements are as follows (D represents the diameter of the pipe):
1.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with liquid flow from bottom to top) that matches the diameter of the sensor. A certain length of straight pipe is required upstream and downstream to ensure accuracy: 15-20D for the front straight pipe section and 5-10D for the rear straight pipe section.
2.
Ensure the pipe near the liquid sensor is completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes that experience strong mechanical vibrations.
4.
The inner diameter of the straight pipe should closely match the sensor diameter. If an exact match isn't possible, use a slightly larger diameter pipe with an error margin ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, cramped spaces, or where maintenance is challenging..
5.
Horizontal pipeline installation is most common. For gas flow measurement, if the gas contains a small amount of liquid, place the sensor at a higher point. For liquid flow measurement, if the liquid contains some gas, the sensor should be placed at a lower point.
6.
Vertical pipeline installation: For gas flow, the sensor can be installed without flow direction concerns. If the gas contains liquid, flow should be from bottom to top. For liquid flow, flow should also be from bottom to top to avoid extra weight on the probe.
7.
Side installation on horizontal pipelines is suitable for various fluids, particularly for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferable to reduce temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally not recommended and unsuitable for general gases or superheated steam. It can be used for saturated steam and high-temperature liquids, especially where frequent pipeline cleaning is required.
9.
For pipelines with insulation layers, when measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
For pressure and temperature measurement points, if required near the sensor, place the pressure measurement point 3-5D downstream of the sensor and the temperature measurement point 6-8D downstream.
