Installation Requirements
Piping Condition
The installation of the High Accuracy Liquid Gas Vortex Flowmeter with Anti Vibration Design mandates the presence of certain straight pipe sections before and after the meter. The typical requirements are detailed below (D represents the pipe diameter):
1.
The sensor must be mounted on a pipe that is horizontal, vertical, or inclined (with liquid flowing upwards) and matches the sensor's diameter. Adequate straight pipe lengths are essential both upstream and downstream of the sensor, requiring 15-20D for the upstream section and 5-10D for the downstream section.
2.
The pipeline adjacent to the liquid sensor must be entirely filled with the liquid being measured.
3.
The sensor should not be installed on a pipeline experiencing strong mechanical vibrations.
4.
The inner diameter of the straight pipe section should closely match the sensor diameter. If it is not feasible, use a pipe with a slightly larger diameter, ensuring the deviation is ≤3% and not more than 5mm. Avoid installing the sensor in areas with strong electromagnetic interference, confined spaces, or where maintenance is inconvenient..
5.
Horizontal pipeline installation is the most common method for flow sensors. For gas flow measurements containing small amounts of liquid, install the sensor at the highest point in the pipeline. For liquid flow measurements with small amounts of gas, install the sensor at the lowest point in the pipeline.
6.
Vertical pipeline sensor installation is viable. For gas flow measurements, the sensor can be mounted on a vertical pipe without flow direction restrictions. If the gas contains small amounts of liquid, the flow should be from bottom to top. For liquid measurements, ensure the flow is from bottom to top to prevent additional load on the probe.
7.
Side mounting of sensors on horizontal pipelines is permissible for all fluids, including superheated steam, saturated steam, and low-temperature liquids. Side installation is preferred when conditions allow, as it reduces temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It is unsuitable for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids. This method is applicable where pipelines require frequent cleaning.
9.
When installing sensors on insulated pipelines, particularly for high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Selecting pressure and temperature measurement points: Depending on the requirements, the pressure measurement point should be positioned 3-5D downstream of the sensor, and the temperature measurement point should be 6-8D downstream.
