1. INTRODUCTION

The Model 104D Rate Totaliser is a microprocessor based instrument, Loop
Powered with a 4-20mA output and Alarms. It accepts a frequency or pulse input
from a wide range of flowmeters. The instrument displays flow Rate, a Resettable
Total and an Accumulated Total directly in engineering units.
The instrument is compatible with a wide range of flowmeters including turbine,
paddlewheel and positive displacement flowmeters.
The instrument is fully programmable from the front panel; the user can program
scaling factors, decimal point positions, filter constants and timebase.
The Model 104D Rate Totaliser conforms to the EMC-Directive of the Council of
European Communities 2004/108/EC, the LVD directive 2006/95/EC and the
