Basic description

MiniElcor is designed for converting of gas volume in operating conditions to gas volume in standard conditions according to state equation. For that purpose, it reads pulses from gas meter, measures gas temperature and pressure. The gas volume corrector is of the PTZ, PT, TZ or T type. The device supports those algorithms for calculation of compressibility factor according to standards AGA 8-92DC, AGA NX-

19 mod, AGA 8-G1, AGA 8-G2, SGERG-88 or fixed.

Mechanical concept of the device is selected to operate as a single channel. Device configuration also enables measuring and monitoring other quantities.

Power supply

The device operates from inbuilt lithium battery for 6 years in defined operating conditions. It is possible to use pulse outputs during battery power supply. In case of request for operation mode with increased consumption, external power supply with intrinsically safe sources can be used (JBZ-02,

DATCOM-K3/K4).

Communication

Communication with superior system

For connection with superior system can be used RS-232 or

RS-485 or infrared optical port.

Communication can be realized through the PSTN modem,

GSM or GPRS modem or with radiomodem. TCP/IP protocol is supported. The device is equipped with communication protocols ELGAS version 2, MODBUS . Another protocols can be used on request.

Communication with modem GSM, GPRS

For the purposes of diagnostics during modem installation, there is realized possibility of representing information from a modem about presence and connection to GSM or GPRS network and information about strength of a signal measured by modem.

Communication and telemetry

Device is equipped with functions which are standard for telemetric systems. It enables monitoring excesses of set limits, sending alarms to control centre, operation of modem and others.

Example of application

MiniElcor is constructed on the latest microprocessor technology which enables measuring of pressure and temperature using analog transducers. The device provides large capacity of archives and enables flexibly to change period of data recording.

As a standard function the device offers generator of output digital pulses which respond to primary and standard volume and alarm signal. Protection of data is secured either by hardware switch or by using programmable passwords.

MiniElcor is designed for complex solution based on flexible modular system. MiniElcor is battery power supplied with option of external power supply. All required actual and calculated values are presented on back lighted graphical LCD display with using of 6-buttons keypad. It is also possible to make basic parametrization through keypad. Communication with superior system can be realized trough serial interface RS-

232/RS-485 or infra-red head.
