Installation Requirements
Piping condition
The installation of the Easy Install Wear Resistant Vortex Flowmeter for Liquid Applications from Shandong Zhongziyi Intelligent Technology Co., Ltd. requires a specific straight pipe configuration both before and after the sensor. The typical guidelines are outlined below (D represents the pipe diameter):
1.
Ensure the sensor is installed on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Maintain a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe adjacent to the liquid sensor must be completely filled with the liquid being measured.
3.
Avoid installing the sensor on pipes experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe should be as consistent as possible with the sensor diameter. If not, use a pipe with a slightly larger diameter, ensuring the error is ≤3% and does not exceed 5mm. Avoid locations with strong electromagnetic interference, limited space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most common. For gas flow with minor liquid content, install the sensor at a higher point. For liquid flow with minor gas content, install it at a lower point.
6.
Vertical pipeline sensor installation: For gas flow, install the sensor on a vertical pipe without flow direction restrictions. If the gas contains liquid, position it for bottom-to-top flow. For liquid flow, ensure bottom-to-top flow to avoid extra weight on the probe.
7.
Side mounting on horizontal pipelines is viable for all fluids, particularly superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred where possible to minimize temperature effects on the amplifier.
8.
Inverted horizontal pipeline installation is generally discouraged, except for measuring saturated steam, high-temperature liquids, or when frequent pipeline cleaning is required.
9.
When measuring high-temperature steam, the pipeline's insulation layer should not exceed one-third of the bracket height.
10.
Pressure and temperature measurement points should be strategically placed: the pressure point 3-5D downstream, and the temperature point 6-8D downstream of the sensor, as per measurement needs.
