The HWM Comlog 2 is a robust GSM/GPRS data logger that remotely monitors flow and pressure, helping to detect leaks, optimize network performance and reduce operational costs with reliable real-time data.
The HWM COMlog 2 is a highly versatile and cost-effective multi-application data logger designed for accurate, reliable, and near real-time monitoring of water and energy consumption. Compatible with any meter or sensor that has a volt-free pulsed output, it uses accumulative pulse counting to convert readings into precise consumption data.
COMlog 2 Built for flexibility which supports GPRS/2G, 4G, LTE-M (Cat-1), and NB-IoT communication options, ensuring dependable data transmission even in remote or low-signal areas. The device comes with an external antenna connection for specialist antennas to further improve connectivity in challenging environments. With a typical 5-year battery life (at 8-hour transmission intervals) and wireless programming capabilities, it significantly reduces maintenance and operational costs.
Data is accessed via HWM Online, a secure multi-utility monitoring platform that allows utilities and departments to track consumption, detect abnormalities, and generate actionable insights from anywhere.

The ComLog 2 is a correlating noise logger system designed for permanent and mobile leak detection in water distribution networks. It combines acoustic noise logging with correlation technology to accurately locate hidden leaks.
ComLog 2 records acoustic leak noise from multiple points on a pipeline and uses cross-correlation algorithms to calculate the exact leak position between logger locations.
Correlation technology provides accurate leak location information, reducing excavation costs, repair times, and unnecessary pipe exposure.
Yes. ComLog 2 can be deployed as a fixed leak monitoring network, continuously monitoring critical water infrastructure and alerting operators to new leak events.
Yes. The system supports wireless data transmission and remote access, enabling operators to analyze leak data without visiting each logger location.
Yes. It is widely used in District Metered Areas (DMAs) to support NRW reduction programs and continuous network monitoring.
Using advanced correlation processing and synchronized acoustic measurements, ComLog 2 can locate leaks with high positional accuracy, significantly reducing field investigation time.
Yes. The highly sensitive acoustic sensors can identify developing leaks before they become major bursts, helping utilities reduce water losses proactively.
ComLog 2 can be used on metallic, ductile iron, steel, PVC, HDPE, and mixed-material water distribution pipelines.
Yes. Data can be viewed and analyzed through centralized software platforms, allowing leak prioritization, trend analysis, and network-wide reporting.
The system uses advanced wireless communication technologies that support reliable data transfer across large water distribution networks.
Yes. Leak severity, location data, and historical trends help maintenance teams focus resources on the highest-priority leaks first.
By continuously identifying hidden leaks and accurately locating them, ComLog 2 enables faster repairs, reducing water losses and improving network efficiency.
Water utilities, municipal corporations, smart city projects, industrial water networks, NRW management programs, and utility contractors.
Key advantages include acoustic noise logging, leak correlation technology, remote communication, DMA monitoring capability, permanent network monitoring, cloud-based analytics, and accurate leak location functionality.
ComLog 2 can be deployed across municipal water distribution networks, District Metered Areas (DMAs), transmission mains, industrial water systems, smart city water projects, and utility infrastructure networks.
Yes. It is specifically designed for DMA monitoring, helping utilities identify hidden leaks and reduce Non-Revenue Water (NRW) losses.
