Essential Installation Requirements
Optimal Piping Conditions
The installation of a vortex flowmeter necessitates specific straight pipe sections both before and after the device. The common scenarios are as follows (where D represents the diameter of the pipe) :
1.
The sensor must be positioned on a horizontal, vertical, or inclined pipe (with the liquid flowing upwards). The pipe must match the sensor diameter and have adequate straight pipe lengths upstream (15-20D) and downstream (5-10D) 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.
Ensure that the inner diameter of the straight pipe section matches the sensor's diameter as closely as possible. If they differ, opt for a slightly larger diameter pipe with an error of ≤3% and not exceeding 5mm. Do not install the sensor where there is strong electromagnetic interference, cramped space, or inconvenient maintenance access..
5.
Horizontal pipeline installation is the most prevalent method for flow sensors. For gas flow measurements containing minor liquid amounts, install the sensor at a higher point. For liquid flow measurements with minor gas amounts, install the sensor at a lower point.
6.
For vertical pipelines: When measuring gas flow, the sensor can be installed without flow direction restrictions. If the gas contains a small amount of liquid, the flow should be bottom-to-top. For liquid flow, position the sensor bottom-to-top to alleviate additional weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is viable for all fluids. This method is especially recommended for superheated steam, saturated steam, and low-temperature liquids as it minimizes the amplifier's temperature impact.
8.
Inverted horizontal pipeline sensor installation is generally discouraged. It is unsuitable for general gases or superheated steam but can be used for saturated steam and high-temperature liquids or in scenarios requiring frequent pipeline cleaning.
9.
For pipelines with insulation layers, ensure the insulation height does not exceed one-third of the bracket height when measuring high-temperature steam.
10.
Choosing pressure and temperature measurement points: Based on measurement needs, the pressure measurement point should be 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream.
