For over 50 years Meriam has been successfully involved in the Averaging Pitot Tube business, mainly through the designing and manufacturing of Accutubes. This success has been established through thousands of effective installations worldwide. While other companies changed their tube to Bullet, Diamond or Flat-Face, with assertions that each is better than the other, Meriam has always used the round probe design providing our customers with low-cost, accurate flow measurement.
The Meriam Accutube brand is field proven to be the most robust and accurate design, from your simplest application to your most difficult. Meriam Quality Assurance programs assures many years of service from the Accutube Flow Meter.
