Technolog – Empowering Utilities for a Smarter, More Sustainable Future
For over 40 years, Technolog Group has been at the forefront of innovation in water, wastewater and gas network monitoring. We provide intelligent, end-to-end solutions that enable utility providers around the world to optimise operations, reduce losses and future-proof their infrastructure.
Technolog’s cutting-edge portfolio is designed for rapid deployment and seamless integration with existing SCADA and telemetry infrastructure. At the heart of our offering is the Cello range—a family of advanced cellular-based data loggers that deliver high-frequency, low-power data transmission offering over 5 years of uninterrupted operation. With Technolog’s product range, organisations can confidently optimise their monitoring capabilities while reducing costs and complexity.
Today, over 450,000 Cello units are deployed in more than 150 countries, making Technolog one of the world’s largest collectors of machine-to-machine (M2M) data in the utility sector.
Comprising Technolog Ltd, Utilitec Services Ltd, and Utility Data Services Ltd, the Technolog Group delivers a full-service ecosystem. From state-of-the-art product development and seamless installation to smart data management and powerful analytics, we deliver comprehensive support designed to propel utility networks forward.
Our success is powered by deep domain expertise in:
• Cellular communications
• SCADA integration
• Remote diagnostics
• IT infrastructure
• Water, wastewater and gas network optimisation
Since launching the first Cello unit in 2000, we’ve continually evolved our technologies to meet the dynamic needs of utilities facing increasing regulatory, environmental, and operational challenges ensuring our clients are equipped to meet both current and future demands.
Cello solutions are trusted by utilities worldwide to monitor critical assets, spanning distribution networks, customer connections, and pressure points. These smart devices allow utilities to manage their clean water networks proactively minimising leakage through early warnings, providing pressure control to maintain consistent service levels, reduce burst frequency and enable data-driven decision-making.
In AMP7 Technolog Group supplied and installed 40,000 Cello Sewer Alarm devices, a year ahead of target, to provide early warning of internal and external sewer flooding events for Yorkshire Water. Consequently, saving Yorkshire Water millions of £s in environmental penalties.
Technolog plays a vital role in helping utilities meet their sustainability goals. Our technologies enable significant water savings — reducing daily losses by hundreds of megalitres — and improving network efficiency through intelligent pressure and leakage management.
With powerful analytics, robust hardware, and resilient connectivity, our solutions unlock actionable insights that empower utilities to deliver more sustainable and reliable services.

Introducing the New Cello Sewer Alarm - Visit us to learn more about our new Cello Sewer Alarm—a cost-effective, robust, and universal solution for remotely monitoring flooding events in customer gullies and sewer or wastewater chambers. These assets are continuously monitored, and flood events are transmitted in real time over cellular networks to alert network operators.
Smart analytics provide vital insights, including when flooding occurs, its duration, and frequency. This enables utilities to access reliable flood monitoring data at any time. Our web-based analytics platform supports predictive maintenance and trend analysis for flood-prone locations, helping to prioritise resources and optimise network operations.
Cello XT & RS1 – Advanced Sewer Level Monitoring. At Technolog Ltd, our development engineers have created an advanced sewer level monitoring solution: Cello XT paired with the RS1 RADAR level sensor. The RS1 is specifically engineered for challenging sewer environments, using sophisticated signal processing to accurately isolate water levels from background noise. Cello XT offers outstanding connectivity and supports multiple sensor configurations, ensuring high-performance data delivery.
AS1 – Smart, Cost-Effective Monitoring for Wastewater Networks. The AS1 is your cost-effective tool for targeted monitoring of wastewater treatment and sewer networks. It enables spill verification at Combined Sewer Overflows (CSOs) for accurate and compliant reporting, compatible with any MCERTS-certified sensor.
Additional features include:
• Precise infiltration detection via angle and temperature sensing
• Misconnection identification to protect both system integrity and the environment
• Ideal for inlet, outlet, and wetwell monitoring at pump stations and treatment works
The AS1 delivers dependable performance where it matters most.
