CRS-03 Data Logger

The CRS-03 Data Logger is dedicated to work with turbine, rotary and diaphragm gas meters equipped with low frequency reed contact pulse transmitter. Its main task is to record the measured volume of flowing gas in real conditions and assign the “peak hour”, i.e. maximum hourly gas consumption together with the moment of its occurance.

A built-in display, permanently active, enables accesspromptly to the most important information for the user.

Recorded information can be passed on via Text messages (built-in GSM module) as well as via OPTO-GAZ optical connection with a suitable optical interfacewhich additionally enables to configure the device locally.

Description

FEATURES

Nice flexible communication between user and CRS-03 Data Logger assured by:
LCD display with good visibility in the whole range of temperatures
Possibility of direct configuration and receiving data via OPTO-GAZ optical connection
Base softwarewhich enables to read outautomatically the device
Two inputs
LF low frequency reed contact pulse transmitter connected with Vm (V1) counter (f<10Hz)
LFb two-position, changing of the state on input can cause instantaneous giving an alarm via SMS  (Short Text Message). Used for cooperation with anti-fraud contact, signaling a brokenpulse conduit or detection of eventual manipulation
Minimum 5 years of work without necessity of battery replacement for standard working conditions
Recorded data (every 1 hour) stored for at least 280 days
Changeable reporting period and the time of sending, possibility of sending detailed data “on request”

COMMUNICATION

Via SMS messages – built-in 900/1800MHz GSM module assures duplex communication via SMS messages between servers and CRS-03 Data Logger  as well as configuration of the CRS-03 Data Logger. Standard message consist of Vm (V1) counter state, increase of reporting period, “rush hour” of reporting period, date and time of reporting period appearance, date and time of sending the report, battery status. On request detailed hour data are sent.
Via OPTO-GAZ which enables to read out the recorded data locally and to configure the device

BASE RECEIVING SERVER

GSM Modem
Computer with software which enables to read out and gather information and configure the device. Software provided by COMMON S.A. enables to:
Configure the device
