INTRODUCTION
The Preso COIN® flow meter accommodates most flows, even the most abrasive . Accuracy and reliability are achieved by its
rugged construction, practical design and simple principle of operation . It stands alone in its ability to maintain the necessary
square root relationship between flow rate and differential pressure for almost any type of flow . Even viscosities up to 3,000
centipoise do not affect the accuracy of the meter . The flow coefficient stays highly predictable down to the remarkably low
Reynolds number of 300 . This makes the meter ideal for traditionally difficult-to-meter applications such as fuel oil, waste
water, coal tar, iron ores, black liquor and others .
