HWM - Model Multilog 2 -Advanced And Versatile Multi-Channel Data Logger
Multilog 2 is the highly advanced and versatile multi-channel data logger designed to monitor any combination of digital and analogue signals. 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, Multilog 2 contains our advanced modem (capable of connecting via LTE-M or NBIoT with 2G fallback, 3G or 2G). Multilog 2 is an effective data logging solution and is available with support for WITS 1.3, delivering direct integration with WITS SCADA systems.
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 2G, 3G, 4G, LTE-M (Cat-M1) 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.
