The FlowSet Accusetter is the leader in the manual, proportionally balanced HVAC environment providing standard-setting performance with accuracy of <3%, flow setting in four simple steps, and thousands of dollars of savings on head and horsepower usage over energy wasting circuit setters.ĪSHRAE recommends that manual balancing valves be placed on the coils, risers, branches, and pump discharge so that the system can be proportionally balanced. They are easy to use - no slide rule required - and have a direct reading GPM gauge available.įlowSet Accusetters perform manual circuit balancing in three important ways - flow measurement, flow adjustment, and flow shut-off. Models are highly accurate and are available to read flow as low as 0.1 GPM. The valves have a low loss venturi section which can save up to 10 feet of pump head when compared to energy wasting circuit setters. How is it piped now I can help with getting the proper size valve. Spend the money on adding pressure independent valves not re piping the boilers. Models feature venturi balancing devices with twin measurement ports. A circuit setter is a fixed orifice devise and the flow rate changes as pressure changes in the system. Installation, Operation, and Maintenanceįlow Design's FlowSet Accusetters are the preferred means for manual balancing of constant speed systems by most engineers and accepted by all.
