Air and Gas Flowmeters

Orange Research's flowmeters have a familiar pointer-and-dial face to ensure accurate measurement readings at a glance. The pointer is magnetically coupled to the flow sensor, which is available in two types: a variable-area orifice, for most applications, and a fixed-area orifice, for where more sensitive measurements are needed. Both sensors are spring loaded, so unlike gravity-based units, these flowmeters can be mounted in any orientation. Three basic models, Series 2020, 2220 and 2320, cover a range of flow rates from 5 to 100 scfm.
