3 Input Meter Logger (Ethernet enabled)

Picture of 3 Input Meter Logger (Ethernet enabled)

The Meter Logger 100 is a simple-to-use interface device which converts the pulse outputs from up to 3 utility meters into both a graphical display on a webpage and formatted downloadable data.

Any utility meters with a volt free pulse output can be connected to the ML100 and the 3 input facility means that for example gas, electricity and water usage can be simultaneously monitored. (Please note to comply with regulations, a gas barrier relay is required when connecting to a gas meter)

The web interface allows consumption information to be remotely viewed and downloaded without the need to be physically near the meters.

The unit always knows the real time as it uses a battery backed clock. When it is unpacked all the user needs to do is to connect it to the meter pulse output and supply power. The Meter Logger will start logging pulses. If power is lost and then comes back, the ML100 will still know the exact time and just carry on logging data into the right half hour slots.

The Meter Logger can also be configured to send energy consumption data via e-mail. Up to two recipients can be designated to receive either daily, weekly or monthly e-mails with the energy consumption data provided as a CSV format attachment. The data file can be customised for compatibility with third party energy management software and can be easily imported into Excel.

Built-in webpages

The unit has built in web pages which can be used to view daily or monthly usage profiles. Configuration settings allow for conversion between meter pulses and normal parameters e.g. 1 pulse equals 0.1 kW.

At our site, we have our electricity meter connected to a meter logger to allow us to monitor the electricity usage. You can check out our meter web pages by visiting http://meter.crucible-technologies.co.uk. Note that the Settings page has been specially configured so that you can view the data but not make any edits.

Additional Connectivity Options

If a wired ethernet connection is not conveniently located close to the utility meters, the Meter Logger can still be deployed due to a variety of other connection options including ethernet over mains and wireless networking. Click Here to download the Connection Options brochure.


The LoggerFind software is a free utility which locates any Meter Loggers connected to a network and displays the IP address of the unit(s). Simply download and execute to find your Meter Logger.
