HVAC and district-energy systems depend on dependable chilled-water, cooling-water and hot-water measurement for load control, energy management and system balancing. Electromagnetic and ultrasonic technologies are widely used because they offer low pressure loss and broad pipe-size coverage.
Correct sizing, adequate straight runs, temperature sensing and communication with the building-management system are important for useful energy data.
