Blue-White's FVS Series flow meters are used for low flow applications. These meters will work with chemical metering pumps and will work with pulsating flows that are notoriously difficult to measure. The working range of flows that can be measured is from 30 mL/min to 7000 mL/min depending on the model chosen. There are options to provide for compatibility with a variety of chemicals using PVDF, PVC, or polypropylene plastics with FKM (Viton) or EPDM o-rings. Rate and total displays are also optional and are surprisingly inexpensive.
