EC Declaration of Conformity for EMR3
Issued by: Veeder-Root Environmental Systems,
Hydrex House,
Garden Road,
Richmond,
Surrey,
TW9 4NR.
This document certifies that the equipment specified below, manufactured by Veeder-Root Co., complies
with the requirements of Council Directives 89/336/EEC (EMC) and 94/9/EC (ATEX).
Description of Equipment (EMR3)
A Veeder-Root EMR3 electronic register, used with meter measuring systems, was examined for
conformance to the standards described in this document. The EMR3 system replaces mechanical
registers, calibration gears, adjuster mechanisms and manual receipts, with an automated system. The
EMR3 system comprises of the Register Head (display), the Interconnect Box and a Printer. The system
works in conjunction with a meter to accurately measure liquid deliveries, control liquid flow and print
priced receipts. Each EMR3 system is electrically powered by either a 24V or 12V direct current supply.
EMR3 Register Head (Display)
Electronic pulses from the meter may be passed to the EMR3, or it may be fitted with an optional internal
pulser unit mechanically linked to the meter. The EMR3 processes the pulses, converting them into
volume using stored calibration values. The unit may also calculate the cost and tax of the delivery.
Transaction records are stored in non-volatile memory for viewing or printing. The results of the delivery
are displayed on the EMR3 and may also be printed on a remote printer. The Head may be fitted with an
optional alphanumeric keypad for ease of data entry. In EMR3 systems with more than one Head, any
single Head may be configured as a Remote Display.
Temperature compensation may also be implemented using an optional temperature probe. An approved
temperature correction algorithm is stored in the EMR3 for automatic correction when the temperature
correction mode is enabled.
EMR3 Interconnect Box
The Interconnect Box provides intrinsically safe power to the register and it is also the control interface
between the register and the rest of the measuring system. Internal relays interface the system electronics
to the system pneumatics. Serial ports provide data communication to and from external devices.
