Introduction

Description and variants

Thanks to its many variants and configuration options, the EC 900 PTZ corrector offers a multitude
of functions and possible uses, ranging from a small solution to a complex one. From a simple bat-
tery-powered device processing LF volume pulses up to an externally supplied device fitted with an
internal radio modem or connected to an external communication module, the type series satisfies
all current requirements for volume correction, archiving and communication.
The EC 900 PTZ corrector has been approved for custody transfer metering in compliance with the
European Measuring Instruments Directive (MID).
The integrated tariff memory can store hourly values for more than six months. Furthermore, there
are archives for daily and monthly values and events as well as logbooks. There is also a legal met-
rological logbook as per PTB-A 50.7 which allows parameters under legal control to be changed
without an inspector from the Weights and Measures Office being present.
The device can be operated either via keys on the device or through an interactive program from
RMG. An electrical interface and an optical interface enable the device to be connected to a PC.
The EC 900 can be used in hazardous areas of Ex zone 1 or 2, depending on its version and equip-
ment. An external communication module with electrical isolation allows the device to be used in
Ex zone 1, while using the communication functions at the same time.

The device variants basically differ in their explosion protec-
tion and power supply (lithium battery or external power sup-
ply). Apart from that, it is also possible to fit the device (de-
pending on its explosion protection) with an internal or exter-
nal communication module (with modem). The individual vari-
ants and combination options are shown in the table below.
