Data Logger

Digitise existing assets

Flow Lotic™

lotic: of, relating to, or living in moving water

The Flow Lotic™ data logger connects to existing commercial analogue meters, providing business customers visibility of water consumption across sites at the main meter and sub-meter level.

Rich Data Set

Deploy with footprint® 2.0 to visualise data, automate anomaly alarms and generate reports.

Suitable for Sub-Metering

Economically installed on sub meters to give business customers a more granular view of water consumption.

Built-in Alarms

Includes built-in and configurable alarms that ensure operators and customers receive the right information at the right time.


Low Lifetime Cost of Ownership

A future-proof solution designed for long term returns

Deployment Flexibility

Compatible with a wide range of meter types and sizes meaning it can be used to digitise a majority of business customer meters. Simplifying device rollout and reducing installation costs.

Designed for Longevity

Fully potted to reduces the risk of device damage. Resilient to network disruptions and stores 10 days of data without needing to send a manual meter reader. The device has a 10 year battery life. The LwM2M protocol used is 33% more battery efficient compared to MQTT.

Low Stranded Asset Risk

Configuration and firmware updates over-the-air ensure the device is always up to date. Uses an open standard LwM2M over NB IoT which is a secure licensed spectrum.

The True Value of Digital Transformation

Utilities are at various stages of exploring digital transformation as an enabler to meet the demands of the future. The most successful transformations will chart a clear path for the future but also recognises that change is inevitable and so flexibility is critical. The challenge for utilities is building the business case that prioritises investment in the short term to preserve freedom for the future
