HVAC & Building Automation Case Study
Integrated Flow Metering Solution Enhances Water and Energy Efficiency in a Premier Hospitality Project
Efficient control of water and energy systems is vital for modern high-rise hospitality infrastructure. For a landmark project in Colombo, Sri Lanka, executed by a leading EPC contractor, IOTAFLOW delivered a complete flow metering solution integrating Electromagnetic, Ultrasonic, and BTU meters. Covering multiple service networks from chilled water and wastewater to domestic and process water the system ensured precise monitoring, optimized energy usage, and seamless Building Management System (BMS) integration for real-time control.
The Challenge – Multi-Utility Monitoring in a Complex Infrastructure
The project featured a mix of luxury hotel facilities, commercial spaces, and technical plants, each requiring accurate measurement of chilled water, HVAC energy, and water consumption. The EPC contractor needed a unified metering solution capable of delivering high-accuracy readings, minimal maintenance, and centralized data access through the site’s automation system.
Traditional mechanical meters lacked the range and integration capability to handle such varied service conditions — from large-diameter chilled water lines to low-flow domestic systems.

The IOTAFLOW Solution – Multi-Technology Precision Metering Network
IOTAFLOW engineered and supplied a hybrid flow metering network customized for the project’s diverse operational requirements.
- 1Electromagnetic Flow Meters:
For treated, domestic, and process water networks requiring high accuracy and stable long-term performance.
- 2Ultrasonic Flow Meters (Clamp-On & Insertion):
For chilled water and wastewater systems where non-intrusive or low-maintenance solutions were critical.
- 3BTU (Energy) Meters:
Installed in chilled water loops to calculate real-time energy transfer and system efficiency within the HVAC network.
- 4Integration & Performance:
All meters were factory-calibrated, configured with MODBUS/RS485 communication, and integrated into the project’s Building Management System (BMS) for consolidated monitoring, trend analysis, and reporting.
