Installation Requirements
Piping Condition
For optimal performance of the Anti Vibration Liquid Gas Vortex Flowmeter with High Accuracy, a certain length of straight pipe section is required before and after the flowmeter. The typical requirements are as follows (D represents the diameter of the pipe):
1.
Install the sensor on a horizontal, vertical, or inclined pipe (with the liquid flowing from bottom to top) that matches the sensor's diameter. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor.
2.
Ensure the pipe near the liquid sensor is completely filled with the liquid being measured for accurate readings.
3.
Avoid installing the sensor on pipes subjected to strong mechanical vibrations to maintain measurement accuracy.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If not, use a slightly larger diameter pipe with an error margin of ≤3% and not exceeding 5mm. Avoid locations with strong electromagnetic interference, limited space, or difficult maintenance..
5.
For horizontal pipeline installations, if measuring gas with a small amount of liquid, install the sensor at a higher point in the pipeline. For liquid with a small amount of gas, install the sensor at a lower point.
6.
In vertical pipelines, the sensor can be installed without flow direction restrictions for gas measurements. If the gas contains liquid, the flow should be from bottom to top. For liquid flow, ensure it moves from bottom to top to reduce probe weight.
7.
Side-mounting sensors on horizontal pipelines is suitable for superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred to minimize temperature impact on the amplifier.
8.
Inverted installation on horizontal pipelines is not recommended for measuring general gases or superheated steam. It is suitable for measuring saturated steam, high-temperature liquids, or in cases where frequent pipeline cleaning is required.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, ensure the insulation does not exceed one-third of the bracket height to maintain accuracy.
10.
When pressure and temperature measurements are required near the sensor, place the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor for precise readings.
