run locally or remotely via an internal modem in the latest generation networks with
different communication protocols
 each communication channel can communicate with different protocol
 communication is completely independent and does not affect the measurement,
computation and data archiving system
 possibility of remote download of the FW according to Welmec 7-2 Extension D
 several degrees of protection against device abuse have been implemented
 changing the device settings locally or remotely
 ELCOR, ELCORplus and ELCORplus indexer as an electronic volume corrector for billing
purposes
 the same technical solution for DATCOM and DATCOMplus electronic data loggers for
station monitoring and control
 open architecture to satisfy new requirements and projects
ELCORplus device
 is the most powerful full-modular model covering all known end-user requirements
 allows battery operation up to 18 years without battery replacement
 connecting gas meters with LF (reed, Wiegand), HF (NAMUR) pulse outputs, or various
types of encoders (NAMUR, SCR +)
 use as a single-channel or two-channel gas volume corrector with the possibility of adding
a non-metrological channel
 modular architecture allows to create different configurations (up to 6 pressure or
temperature transducers, 12 digital inputs, 4 digital outputs, 6 analog inputs and 4 analog
outputs)
 battery power supplied devices with an option of external power supply for ELCORplus /
DATCOMplus
 Reading of NAMUR or SCR encoder in battery mode (without external power supply)
 4 independent communication channels with high communication speed (up to 115kBd)
 possibility to connect two modems (internal / ex external)
ELCOR
 simplified variant of the device
 single channel variant, battery power supply
 connection of the meter to the LF (reed, Wiegand) with a pulse output or an encoder
output (NAMUR or SCR +)
 2 x binary input, 2x digital output, 1 RS232 / 485 communication line, 1x internal modem
or 2nd RS232 communication line
 3 independent communication channels with high communication speed (up to 115kBd)
1.2 Securing the Device
The device is equipped with the following mechanisms against abuse:
Sealing the device
 sealing of the closed device with the seal of the user and the possibility of locking the
device by a lock (par. 5.2 and 5.6.1.2)
 sealing of the internal pressure transducer nut
 sealing of mechanical indexer screws for connection to the gas meter flange
 sealing the screws of the mechanical indexer setting cover
 sealing the connection of the pressure transducer to the pipeline (par. 5.4.4)
 sealing the connection of the temperature transducer to the pipeline (par. 5.4.5)
Sealing of the internal parts (par. 5.2)
