Multilog 2 WW

Multilog 2 WW

Wastewater networks face constant challenges: blockages, surcharge events, and overflows can quickly escalate into costly cleanups, environmental penalties, and service disruptions. Operators often struggle with limited visibility, unreliable data transmission in poor signal areas, and equipment that fails prematurely in harsh conditions — leading to higher maintenance costs and reduced efficiency. 

That’s where the HWM Multilog 2 WW makes a difference. Specifically designed for wastewater networks, Multilog 2 WW delivers real-time monitoring of level, flow, and surcharge events, giving operators the insights needed to detect blockages early, prevent overflows, and improve overall network performance. 

Equipped with advanced LTE-M and NB-IoT connectivity with 2G/3G fallback, it ensures dependable data transmission even in weak signal areas, so operators always have continuous visibility of their network. Its IP68-rated, corrosion-resistant housing guarantees long-term reliability in submerged, humid, and chemically aggressive environments, eliminating frequent replacements in locations where ATEX certification is not required. 

With up to 8 sensor channels and support for analogue, digital, Modbus, and SDI-12 inputs, along with integrated control outputs, Multilog 2 WW offers unmatched flexibility. From level, velocity, and flow monitoring to water quality measurement, a single device can cover multiple applications. 

And with a 5-year battery life, optional external power, and remote firmware updates, operators benefit from lower maintenance costs, fewer site visits, and maximum system uptime. 

What It Does 

• Continuously logs and transmits wastewater and environmental data from multiple connected sensors. 
• Supports level, velocity, flow, and water quality monitoring in real time. 
• Records statistical data (max, min, average, standard deviation) for accurate trend analysis. 
• Provides state event logging for triggers like float switches, rainfall events, or overflow detection. 
• Controls third-party devices such as automatic water samplers via programmable outputs. 
• Enables high-speed data logging with a secondary channel operating at up to 25 Hz for event-critical applications. 

How It Helps  

• Municipal Wastewater Boards – Monitor sewer levels, flow rates, and quality to prevent overflows and ensure regulatory compliance. 
• Urban Development Authorities – Support Smart City drainage and stormwater monitoring systems. 
• Pollution Control Boards – Collect continuous water quality data to detect contamination and enforce environmental laws. 
• Irrigation & Water Resources Departments – Track canal, drain, and river flow to manage flood risk and water distribution. 
• Disaster Management Agencies – Deploy in flood-prone areas for real-time water level alerts. 
• Industrial Estate Management Authorities – Monitor effluent discharge and compliance in industrial wastewater systems.  

Applications 

• Sewer and stormwater level monitoring. 
• Wastewater velocity and flow measurement. 
• Continuous water quality monitoring (e.g., pH, turbidity, conductivity). 
• Flood risk management and drainage system performance tracking. 
• Control of external devices such as water samplers or alarms. 
• River, canal, and reservoir inflow/outflow monitoring. 
• Environmental compliance monitoring for industrial effluent.
