Installing a thread connection vortex flow meter involves several key steps to ensure proper function and accurate flow measurement. The installation process is generally straightforward, but attention to detail is crucial. Here’s a step-by-step guide on how to install a vortex flow meter with a threaded connection:

1. Pre-Installation Considerations

• Check the Flow Meter: Ensure the vortex flow meter is the correct size for the pipe and is calibrated for the fluid you intend to measure (e.g., gas, liquid, steam).
• Inspect Pipe and Thread: Verify that the piping system has matching threaded connections and is clean, free from debris, and free from any existing damage.
• Orientation: Vortex flow meters are typically installed horizontally, but depending on the design, they may be installed vertically as long as the fluid flows in the correct direction as indicated by the meter's arrow.

2. Select an Installation Location

• Straight Pipe Length: Ensure the pipe section where the meter will be installed has sufficient straight pipe lengths both upstream and downstream for accurate readings.
  • Upstream: Typically, 10 to 20 pipe diameters of straight, unobstructed pipe length are needed before the meter.
  • Downstream: Generally, 5 pipe diameters of straight pipe are recommended after the meter.
• Avoid Disturbances: The flow meter should be installed away from sources of turbulence, such as valves, bends, reducers, or other fittings, as these can affect accuracy.
• Flow Direction: Ensure that the flow direction matches the arrow printed on the flow meter housing.
