Data Loggers vs AMR, what’s the difference?

Businesses are often focused on making efficiencies and cost savings wherever they can. This regularly includes assessing energy usage, but what about water consumption? By effectively managing and monitoring their water usage businesses can save water, benefit the environment and often reduce their water bill.

So how do you monitor your water usage? There are a couple of ways to monitor your usage – either by using a Data Logger or an AMR (Automated Meter Reader). Both are effective water management tools but which is best?

Data Loggers

A Data Logger is a piece of equipment that is used to monitor water consumption. Data is collected and transmitted over mobile networks and is either available to view in almost real time or within 24 hours. Businesses of all sizes will benefit from understanding their water usage; it means that they can closely monitor their water usage and therefore are able to identify any leaks, areas of high usage or any other unusual activity straight away, before any damage has taken place or unexpected costs have been incurred. Data Loggers can be placed at a number of strategic points across a site and used together to comprehensively monitor an entire sites water consumption. Instant alarms are a feature of Data Loggers that many customers find invaluable. When a limit is reached an instant alarm will be sent to the customer, alerting them to emerging issues such as leakage – this instant alarm system can save businesses thousands of pounds on their water bill.



An AMR (Automated Meter Reader) enabled meter provides customers with a snapshot view of their sites water consumption. Attached to the water meter an AMR unit periodically relays meter readings to the water provider. This snapshot of information is mainly used to calculate a customers’ water bill and cannot be used to track real time consumption. By using an AMR a customers’ bill will be based on accurate consumption rather than estimates. Although lacking the sophistication of a Data Loggers instant alarm system, AMR units can sometimes feature alarms which offer retrospective leakage appraisals, however the information is not as detailed as that which is collected by a Data Logger.


Which is best?

So which is best – an AMR or a Data Logger? An AMR periodically collects a snapshot of information, compared to a Data Logger which consistently collects detailed information about a sites water consumption. We believe that ultimately most businesses will benefit from a installing a Data Logger, as the insight it gives into water consumption can be invaluable, especially in the face of an expensive leak.
