Installation Guide
Installation steps for an insertion-type vortex flow meter:
- Use gas welding to create a circular hole slightly smaller than φ100mm in the pipeline. Clean the area around the hole to ensure smooth probe rotation.
- Weld the manufacturer’s flange short pipe to the circular hole in the pipeline, ensuring the flange axis is perpendicular to the pipeline axis.
- Install the ball valve and sensor onto the welded flange.
- Adjust the screw to ensure the insertion depth meets requirements (ensuring the probe’s center axis coincides with the pipeline’s center axis). The fluid flow direction must be consistent with the indicator arrow on the direction indicator.
- Tighten the screws on the gland evenly. (Note: The tightness of the gland determines the instrument’s sealing performance and whether the screw can rotate.)
- Check that all steps are completed correctly. Slowly open the valve to observe for leaks (pay special attention to personal safety). If leaks are found, repeat steps 5 and 6.
- Ensure there is a flow meter upstream of at least 15D and downstream of at least 5D of straight pipe.

More Technical Support and Cases
The insertion vortex flow meter is a new type of flow meter developed based on the principle of liquid vibration. It is widely used for fluid measurement in industries such as petroleum, chemical, metallurgy, and papermaking. It is unaffected by the temperature, pressure, viscosity, and composition of the medium, and is non-clogging, non-jamming, and resistant to scaling. It is also resistant to high temperatures and pressures, safe, and explosion-proof, making it suitable for harsh environments.
Sino-Inst’s insertion vortex flow meter has no moving parts, ensuring high reliability, high accuracy, and a long service life. It can accurately measure the instantaneous and cumulative flow of liquids over a wide flow range. We support customized measurement parameters.
