The FTB300 Series of digital paddle wheels are an economical choice for low flow rate applications. They use Infra-red light beam technology. Available connections include 1/8 FNPT, 1/4 FNPT and 3/8" OD tube fittings. Six available flow ranges as low as 30ml/min to 7000 ml/min. No display models have a 5 Vdc current sinking pulse output. Units with displays have a 6-digit LCD, with up to 4 decimal positions that display both flow rate and total. All units include an open collector alarm output.
User selectable scale factors include: flow units, gallons, liters, ounces, and milliliters. Time units include: minutes, hours, days. Users can also program custom units. Programming values and total are stored in the non-volitile memory. The total reset function can also be disabled. Standard units have a clear PVC viewing lens, PVDF chemical resistant lens are available as an option. The enclosure is a weather resistant Valox PBT and rated NEMA 4X (IP56).
