This session covers the fundamentals surrounding water flow measurement in hydronic systems. Why, how, what. Hydronic systems (chilled water, heating hot water, or condenser water) are effectively a HVAC transmission. Pumps, pipes and valves make-up the envelop and their effectiveness can be measured by the volume flow rate of water in the pipe. We measure flow rate through pressure drop - such as valves, orifices, venturis, equipment losses; by pump curve; and with throughput measurement equipment such as ultrasonic and magnetic meters. The merits and practicalities of each are covered here.
