Page 4: Introduction
Series: iMRM and iMRM-TWIN 1 INTRODUCTION The DRESSER iMRM Rotary Piston Gas Meter is a positive displacement type of meter which, by means of two counter-rotating impellers and a counting mechanism, measures a known volume of gas with each rotation. As a result of years of development and experience, DRESSER has been able to provide a meter of unparalleled accuracy and turn down ratio. - Page 5 Using a special coupling, the index of the meter can be changed on-site with the meter in-line. This enables to change the functionality in the future by just “one click”. The Index is already prepared for the most commonly used functions. For information regarding availability contact DRESSER or the DRESSER representative.
