Piping Condition
The installation of the Low Pressure Loss Vortex Flowmeter requires specific straight pipe sections both upstream and downstream. The usual configurations are as follows (D represents 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 installed on a horizontal, vertical, or inclined pipe (with liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a straight pipe length of 15-20D upstream and 5-10D downstream of the sensor to achieve optimal performance.
2.
The pipe around the liquid sensor must be filled with the liquid being measured to ensure accurate readings.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations, as these can affect accuracy.
4.
The inner diameter of the straight pipe should closely match the sensor's diameter. If a perfect match is not possible, use a slightly larger pipe with an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or difficult maintenance access..
5.
Horizontal pipeline installation is the most common for flow sensors. For gas flow containing minor liquid amounts, install the sensor at a higher point. For liquid flow containing minor gas amounts, install the sensor at a lower point.
6.
For vertical pipeline installations, the sensor can be positioned without restrictions on flow direction when measuring gas. If the gas contains minor liquid amounts, the flow should be from bottom to top. For liquid flow, ensure it moves from bottom to top to avoid adding weight to the probe.
7.
For horizontal pipelines, sensors can be side-mounted regardless of the fluid type. This is especially advantageous for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to minimize temperature effects on the amplifier.
8.
Inverted installation on horizontal pipelines is generally discouraged. It is unsuitable for most 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 that the insulation does not exceed one-third of the bracket height when measuring high-temperature steam.
10.
Placement of pressure and temperature measurement points. Depending on measurement needs, position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream from the sensor.
