Multilog 2 is the highly advanced and versatile multi-channel data logger designed to monitor any combination of digital and analogue signals.

Multilog 2 is ideal for a wide variety of specialised applications, including monitoring PRV flow and/or pressure in a district or zone to assess demand, leakage and conformance.

Accurate, powerful and robust, Multilog 2 is an effective data logging solution.

 

Application

After installation, all firmware upgrades and programming changes are made remotely.  As well as ensuring that changes are made efficiently, this is also cost-effective, as it removes the need for site visits.

Multilog 2 transmits data through an integral modem with GPRS/2G, 4G. LTE-M (Cat-1) and other NBIoT cellular options available.

An innovative feature of Multilog 2 is a secondary channel, enabling additional fast logging down to 25Hz. Secondary logging can be triggered on time schedule and/or in response to an alarm condition being triggered.

This is invaluable when more detailed investigation is required, such as pressure spikes and ‘true’ minimum night flow.
