Installation Requirements
Piping Condition
Optimal installation of the vortex flowmeter necessitates a specified length of straight pipe section both upstream and downstream. The general guidelines are as follows (D represents the pipe diameter):
1.
The sensor should be mounted on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) matching the sensor's diameter. Ensure a straight pipe length of 15-20D upstream and 5-10D downstream to meet proper flow conditions.
2.
The section of pipe around 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.
Ensure the inner diameter of the straight pipe section is consistent with the sensor diameter. If alignment isn't possible, use a pipe with a slightly larger diameter, ensuring an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or difficult maintenance..
5.
For horizontal pipelines, the most common installation method for flow sensors, install the sensor at a higher point in the pipeline when measuring gas with a small amount of liquid. For liquid measurements containing a small amount of gas, install the sensor at a lower point in the pipeline.
6.
In vertical pipelines, sensors can be installed without flow direction restrictions when measuring gas. If measuring gas with a small amount of liquid, ensure flow from bottom to top. For liquid flow, the direction from bottom to top is essential to prevent additional weight on the probe.
7.
Side installation on horizontal pipelines is versatile, suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible, as it reduces the temperature's effect on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is not ideal for general gases or superheated steam but can be used for saturated steam and high-temperature liquids, especially where frequent pipeline cleaning is necessary.
9.
For pipelines with insulation layers measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
When pressure and temperature measurements are required near the sensor, position the pressure measurement point 3-5D downstream, and the temperature measurement point 6-8D downstream from the sensor.
