COMLog 2

COMlog 2

COMlog 2 is the highly versatile data logger designed to be a cost-effective, multi-application data logging solution.

Developed for flexibility, COMlog is compatible with any sensor or meter that has a volt-free pulsed output.

Particularly effective for smart metering, COMlog 2 provides businesses with an efficient way of managing water and energy consumption and reducing costs.



COMlog 2 is compatible with any meter that has a volt-free pulsed output and uses accumulative pulse counting technology to calculate index readings against a known volume.

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

The replaceable internal batteries will typically power the device for over five years when data is transmitted every eight hours.

COMlog 2 is also supplied with an external antenna connection that enables the use of a range of specialist antennas to address the most extreme low signal level locations.
