Incorrect flow meter installation can lead to measurement errors, equipment damage, and process inefficiencies.
Ultrasonic flow meters can be installed vertically, but proper orientation and installation guidelines must be followed to ensure accurate measurements and prevent air entrapment.
Vertical Flow Meter Installation
I’ve helped numerous customers with flow meter installations, and I’ll share key insights to ensure your vertical installation succeeds.
Can a Flow Meter Be Installed Vertically?
Many installers worry about vertical installations affecting measurement accuracy.
Yes, flow meters can be installed vertically, but the flow direction should be upward to ensure pipe remains full and air bubbles naturally escape.
