Electromagnetic Flow Monitoring for HVAC Cooling at Unicom Zhongyuan Data Center
Project Overview
Zhengzhou Unicom Zhongyuan Data Center requires reliable cooling water circulation to maintain stable operation of its air-conditioning system. Accurate supply and return water flow data helps operators monitor cooling performance and identify abnormal system conditions.
Solution Provided
Supmea electromagnetic flowmeters were installed on the supply and return water pipelines in the data center’s air-conditioning plant room.
When the customer encountered unstable and fluctuating flow readings, Supmea provided technical guidance for system inspection and instrument commissioning. The issue was successfully resolved, restoring stable flow monitoring.

Benefits Delivered
- Continuous monitoring of HVAC supply and return water
- Improved visibility into cooling water circulation
- Stable flow data after on-site troubleshooting
- Faster identification of abnormal flow conditions
- Technical support for installation and commissioning

Conclusion
Supmea electromagnetic flowmeters provide essential flow data for the data center’s HVAC cooling system. Combined with responsive technical support, the solution helps maintain reliable cooling water monitoring and stable facility operation.
