DATA LOGGER

MICROLOG
have developed an ultra-low cost solution for the logging of data generated by pulse output water meters. This device can be fitted to any meter which is equipped with a pulse output, and provides the user with a fully configurable memory device capable of logging large amounts of water for domestic and bulk meters.

The Microlog Data Logger is designed to provide a graphic representation of the rate of water usage through a water meter, so as to make water loss management and end user or consumer load profiling a simple exercise.

Features
The Data Logger is equipped with a Real Time Clock (RTC) which time stamps each meter pulse. This allows for detailed analysis of the flow through the meter and allows the water service provider to take synchronized readings of all metering points equipped with Microlog Data Loggers. Meter readings can be stored down to intervals of 1 reading per second and the device currently supports 50,000 readings. Once the memory capacity of the device has been reached, the Data Logger will overwrite the oldest recorded data with new data so as to always provide the most recent available data (First In First Out or FIFO).

The following table illustrates the memory capacity of the standard device with a capacity of 50,000 readings, assuming that the logger is continuously metered at a specific rate:



Logger Reading and Communications
The Microlog Data Logger communicates with Field Service Terminals (FST) or Notebook Computers using short range infrared communication protocol based on the IEC 61107 specification. The profile stored in the Microlog Data Loggers can be read simply by holding the communication interface to the Logger.Data is then downloaded directly to the FST, Notebook or PC for analysis.

Configuration and Reprogramming
Configuration of the Data Lo9gger would typically include synchronising the time of the logger clock with the Field Service Terminal (FST), setting the recording start time and Duration and selecting the scaling factor required. Additional Parameters such as recording Meter ID numbers, GPS location or address and recording any comment or narration specific to the exercise are also supported. Configuration is undertaken by authorised FST using the Microlog Dash Board. The Data Logger can be password protected to ensure security and integrity of the data and configuration. Downloading of profile data does not affect the logger settings and does not require password protection. The Data Logger can be reprogrammed at any time and does Not require the logging service to be complete.

Software
The simplicity of the device ensures that no proprietary software systems are required to analyse data. The Microlog software installed on the FST or Notebook computer provides for the option to export Logger data in a text file using a comma delimited file format.

The data can then be imported into almost any billing, GIS or CRM system, and can even be examined and graphically Manipulated using Microsofttm Excel or similar spreadsheet packages.

The Microlog software does provide graphic analysis tools.
