1. INTRODUCTION
The Model 102A Rate-Totaliser is a microprocessor based instrument designed to
measure a 4-20mA signal from flowmeters and pressure transducers. The
instrument can be programmed to display directly in engineering units and
includes features such as linear or square law calculation, integration and digital
filtering.
Rate, Total and Accumulated Total can be displayed in engineering units on the
large LCD display. A front panel switch selects the function for display and a Reset
button allows the Total to be reset to zero.
The instrument is fully programmable, with all calculation constants set via the
front panel switches and stored in a non-volatile memory which will retain data
indefinitely. The user can program span, filtering levels, display resolution and
cutoff point.
The instrument is powered from a 4-20mA input signal and therefore, requires no
external power.
The Model 102A 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 6.4
must be followed.
