Get started with remote reading and expand or upgrade your system as your needs change. The Meter comes with built-in communication and remote reading that is handled easily through a drive by solution or a fixed network. This lets you significantly decrease your data collection time and enables you to avoid time-consuming follow-ups on lacking or imprecise readings.

Intelligent alarms from the ultrasonic water meter lets you detect leaks and bursts or other irregularities such as tampering attempts or reverse flows quickly and effectively. This limits water loss as well as any collateral damage and enables you to provide a more proactive customer service. If you are looking to get started with more advanced data analytics, MULTICAL® 21 also provides the foundation for hourly calculations of the water loss in each of your districts.

Additional feature

The Flecto Sense Concentrator

The concentrator facilitates AMR (Automatic Meter Reading) to read meters on fixed network, walk-by or drive-by modes. The FSC works with all Kamstrup WMBus devices and the whole range of Flecto Sense WMBus products..

The system is unique in the way the data is always encrypted. You can count on accurate readings, timely responses, data that you can use and report the way you want to.

The FSC records all the WMBus information four times an hour. These readings get sent to the Flecto Backend server where the data is stored for 32 days. The data can be viewed, exported, displayed, printed or imported into other systems. Standard integration via REST API or web portal access from smartphones, tablets and computers.
