This page is intentionally left blank Rev 1 Ultrasonic Serial I O Interface 1 INTRODUCTION The components of this Ultrasonic Meter Interface application identified as 02Q017 are The Serial I O Module with embedded ultrasonic application A user program for handling the Serial I O Module This user manual Form A6133 The Serial I O Module programmed at the factory with the Ultrasonic Meter application provides an interface between ROC300 Series with FlashPAC or FloBoss 407 units and a Daniel Ultrasonic Meter USM The Module polls the meter retrieving flow and diagnostic information The application allows communication with up to four multi dropped Ultrasonic Meters This application assumes that pressure and temperature transmitters are wired directly to the ROC300 Series or FloBoss 407 unit The Pulse Input from each Ultrasonic Meter is also wired to the ROC or FloBoss to provide it with an uncorrected pulse rate The ROC FloBoss takes these inputs and performs AGA7 and AGA8 calculations to provide the corrected flow The Serial I O Module only provides the ROC FloBoss with K factor and diagnostics information The actual flow calculation is always performed by the ROC FloBoss The ultrasonic meter interface which is embedded by the factory in a Serial I O Module RS 485 allows the ROC FloBoss to communicate with a Daniel Ultrasonic Meter without requiring a communications port to be used This manual descri
