PACKING & SHIPPING
We will deliver your ordered product at the earliest date as per your requirements, ensuring prompt and timely service to meet your project deadlines.Installation Requirements
Piping Condition
The installation of the vortex flowmeter requires a specific length of straight pipe both before and after the meter. The common requirements are as follows (D indicates the diameter of the pipe):
Piping condition | upstream | Downstream |
Concentric shrinkage pipe full open gate valve |
15D | 5D |
∠90° square elbow | 20D | 5D |
Same plane 2∠90°elbow | 25D | 5D |
Semi-open gate valve regulating valve | 50D | 5D |
Different plane 2∠90°elbow | 40D | 5D |
With rectifier tube bundle | 12D | 5D |
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that has the same diameter as the sensor. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor.
2.
The pipe near the liquid sensor must be completely 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 closely match the sensor diameter. If an exact match isn't possible, use a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Do not install the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow with small amounts of liquid, mount the sensor at a higher point in the pipeline. For liquid flow with small amounts of gas, mount the sensor at a lower point.
6.
For vertical pipeline installations, the sensor can be installed without flow direction constraints for gas flow. If the gas contains some liquid, the flow should be from bottom to top. For liquid flow, ensure the flow is from bottom to top to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is possible for all fluids, including superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred where feasible as it reduces temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for general gases or superheated steam but can be used for saturated steam or high-temperature liquids and in situations requiring frequent pipeline cleaning.
9.
When measuring high-temperature steam, ensure the insulation layer doesn't exceed one-third of the bracket height for sensor installation.
10.
Selecting pressure and temperature measurement points: Depending on the requirements, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream.
