How to install Gas Turbine Flowmeter Correctly?

SGW Series Gas Turbine Flow meters are widely used to measure gas, natural gas, LPG, biogas ,air and so on .  We always select a proper type gas turbine flow meters for customers , meanwhile ,customers need to pay attention to the installation of the gas turbine flow meters to get the best gas measuring result.
Below is the articles to talk about cautions when install the turbine flow sensor.

Mounting Positions

Turbine flow meters should be installed at the place in compliance with the requirements below:


  • Easy maintenance
  • No electromagnetic interface
  • No vibration
  • Away from heat source



Gas Flowmeter Mounting Orientation

All turbine flow meters are designed to measure flow in only one direction. The direction is indicated by the arrow on the body.


Required Straight Pipelines For Gas flow Sensor

Flow altering device such as elbows, valves and reducers can affect accuracy. See diagram 1 for typical gas turbine flow meter system installation.

The recommended gas turbine flow meter guidelines are given to enhance gas flow meter accuracy and maximize performance of gas turbine flow meter.Distance given here are minimum requirements; double them for desired straight pipe lengths.

• Upstream: allow a minimum straight pipe length at least 10 times the internal diameter of the pipe. For example, with the 50mm pipe, there should be 500mm of straight pipe

immediately upstream. Desired d upstream straight pipe length is 1000mm.

• Downstream: allow a minimum straight pipe length at least 5 times the internal diameter of the pipe. For example, with the 50mm pipe, there should be 250mm of straight pipe

immediately upstream. Desired d upstream straight pipe length is 500mm.


See diagram 2 for straight pipe length requirement when there is altering device.

Warning: Precaution for direct sunshine and rain when the flow meter is installed outside.


Special Notice

  • Foreign material in the gas being measured can clog the meter’s rotor and adversely affect accuracy. If this problem is anticipated or experienced, install screens to filter impurities from incoming gas.
  • When the meter contains removable cover plates. Leave the cover plate installed unless accessory modules specify removal. Don’t remove the cover plates when the meter is powered, or electrical shock and explosion hazard can be caused.
  • Avoid opening the valve from shut to full open, as the sudden flow can cause permanent damage on gas flow turbine’s rotar.
