Installation Requirements
Piping Condition
The installation of the Vortex Flowmeter for Steam with Anti Vibration and Low Loss mandates a certain length of straight pipe section before and after the meter. The common situations are as follows (D represents the diameter of the pipe):
1.
The sensor should be installed on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) matching the sensor diameter. Ensure a straight pipe section upstream and downstream of the sensor, with a length of 15-20D for the front and 5-10D for the rear.
2.
The pipeline near the sensor must be filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations.
4.
Ensure the inner diameter of the straight pipe section closely matches the sensor diameter. If not possible, use a slightly larger diameter pipe, with an error of ≤3% and not exceeding 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, restricted space, or difficult maintenance..
5.
Horizontal pipeline installation is most common for flow sensors. For gas flow containing a small amount of liquid, install the sensor at a higher point. For liquid flow containing a small amount of gas, install the sensor at a lower point.
6.
Vertical pipeline installation for sensors. For gas flow, install the sensor without flow direction restrictions. If the gas contains a small amount of liquid, flow direction should be from bottom to top. For liquid flow, ensure the liquid flows from bottom to top to avoid adding weight to the probe.
7.
Side mounting of sensors on horizontal pipelines. Regardless of the fluid, side mounting is preferred, especially for superheated steam, saturated steam, and low-temperature liquids, as it minimizes temperature impact on the amplifier.
8.
Inverted installation of sensors on horizontal pipelines is generally not recommended. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or frequently cleaned pipelines.
9.
For pipelines with insulation layers, when measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: If required, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
