Essential Installation Requirements
Optimal Piping Conditions
To ensure the precision of our Vortex Flowmeter, it is crucial to have specific straight pipe sections before and after the installation point. Below are the standard recommendations (D = pipe diameter):
1.
Install the sensor on a horizontal, vertical, or inclined pipe (liquid flowing from bottom to top) with a diameter identical to the sensor. Maintain a straight pipe length of 15-20D upstream and 5-10D downstream to ensure accurate readings.
2.
Ensure the pipe near the sensor is completely filled with the liquid being measured for optimal performance.
3.
Avoid installing the sensor on pipes that are subject to strong mechanical vibrations to maintain measurement accuracy.
4.
The inner diameter of straight pipe sections should match the sensor diameter. If not feasible, use a slightly larger pipe with a diameter error ≤3% and not exceeding 5mm. Do not place the sensor in areas with strong electromagnetic interference, restricted space, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is preferred for flow sensors. For gas flows with minor liquid content, position the sensor at the highest point in the pipeline. For liquid flows containing gas, position it at the lowest point.
6.
Vertical pipeline installation is suitable for gas flow measurements without flow direction constraints. If gas contains liquid, the flow should be upwards. For liquid flows, installing the sensor with an upward flow minimizes added weight on the probe.
7.
Side installation on horizontal pipelines is versatile for all fluids, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when conditions allow, to reduce temperature influence on the amplifier.
8.
Inverted installation is generally discouraged. It is unsuitable for most gases and superheated steam but can be used for saturated steam and high-temperature liquids, or when frequent pipeline cleaning is necessary.
9.
When measuring high-temperature steam, ensure the insulation layer on the pipeline does not exceed one-third the height of the sensor bracket.
10.
For selecting pressure and temperature measurement points, place the pressure tap 3-5D downstream and the temperature sensor 6-8D downstream of the flowmeter for accurate readings.
