1. INTRODUCTION
The Model 202Di Rate Totaliser is a microprocessor based instrument
which 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.
Three different versions of the Model 202Di are available:
1. A Battery Powered Version with no output.
2. A DC Powered Version with either:
i. high and low flow alarms or
ii. a low flow alarm and pulse output.
3. A Loop Powered Version with 4-20mA output and alarms as above.
The instrument is fully programmable from the front panel; the user can
program scaling factors, decimal point positions, filter constants and timebase.
The Model 202Di Rate Totaliser conforms to the EMC-Directive of the Council of
European Communities 2014/30/EU, the LVD directive 2014/35/EU and the
following standards:
EN61326:2013 Electrical equipment for measurement, control
and laboratory use – EMC requirements :
Residential, Commercial & Light Industry
Environment & Industrial Environment.
EN61010:2010 Safety requirements for electrical equipment for
measurement, control, and laboratory use.
In order to comply with these standards, the wiring instructions in Section 9.5
must be adhered to.
