The AFL Automatic Flow Limiter is a unique, patented design that provides test and balance engineers, commissioning agents, installing contractors, and building owners the ability to measure flow while automatically limiting the flow rate to the system requirements. The combination of these two functions into one device expedites the commissioning process in an HVAC hydronic system by reducing the need for a secondary flow measurement device or method, said the company. According to the manufacturer, the device provides an easy and accurate way to report the actual flow rate through a coil for the commissioning report, and it can be performed without the need for any special equipment. If problems ever arise in the hydronic system, the AFL can aid in the diagnostics and troubleshooting process. Features include a 300 Series stainless steel cartridge with a large, fixed inlet orifice and pressure-regulating orifice. The unit has a rugged, clog-resistant, pressure-independent design.
