Tinytag Energy Logger: Accurate Energy Consumption Data

The Tinytag Energy Logger is a portable and non-invasive device for recording single and three phase power usage. It can be used to monitor energy consumption in line with ESOS, ISO 50001, and other energy management requirements, helping to build consumption profiles, monitoring electrical distribution and providing sub-metering information.

The easy to use, self-configuring logger can be used for spot-checks or for longer term recording. Non-invasive flexible coils are used to monitor the current in each phase of a three phase supply while the voltage information may be obtained via a standard 13A wall socket.


Recorded data is downloaded to a PC, where it presented initially in graphs and tables in the Tinytag Explorer Software. Results from separate logging runs can be combined for comparison and analysis.


For example, European Freeze Dry, a leading freeze drying facility and services provider, monitors the energy consumption of all plant and equipment at its site. The Tinytag Energy Logger is used in 24 hour periods on equipment such as vacuum pumps, vacuum boosters, air compressors, pumps etc. The recorded data is analyzed to identify areas where usage or loading of equipment can be reduced. Where modifications to systems or practices are implemented the equipment will then be monitored again to quantify savings and efficiencies.


Similarly, Hampshire-based Celab is a relatively high user of electricity, typically 55,000-70,000KWH/month. Celab designs and manufactures high reliability power supplies for military and commercial applications. With 2000m2 of manufacturing space housing a variety of equipment and processes, Celab purchased an Energy Logger to understand the power usage of individual pieces of equipment and to help identify where potential energy usage savings can be made.


The Energy Logger costs £795 +VAT and is manufactured in the UK by Gemini Data Loggers.
