Omega FTB316D
Liquid Micro-Flow Sensor


Since its inception in 1962, OMEGA has grown from manufacturing a single product line of thermocouples to an established global leader in the technical marketplace, offering more than 100,000 state-of-the-art products for measurement and control of temperature, humidity, pressure, strain, force, flow, level, pH and conductivity. OMEGA also provides customers with a complete line of data acquisition, electric heating and custom engineered products.

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 30 mL/min to 7000 mL/min. Models without a display 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 (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 PVDF chemical resistant lens.The enclosure is weather resistant Valox® PBT and is rated NEMA 4X (IP56).
