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).

Great productGood and precise flow meter, in addition, should have a hard reset switch, in case of the error
When this meter totals the volume does it account for reverse flow by subtracting from the volume total so that a tank level can be estimated from flow in and out?
Asked by: stephen78998
No matter which direction the paddlewheel spins the meter will accumulate a positive total.

Is there an wiring schematic for the flow meter itself, instead of just the strainer that's in the manual? I'd like to output the signal to another unit if that's possible.
Asked by: alexjlove
We can send a copy of the wire schematic for this flow meter, please send that request to email@example.com which would be much appreciated.

The flowmeter stopped working after 4 months installed in a pressure manifold. The sensor had continuous power during the time, the failure was found on the infrared sensor once the flowmeter was replaced. What is the life expectancy of the sensor?
Asked by: Rvasques
Thanks for your question. The life expectancy of the flow meter depends on the each individual application. Customers have this flow meter after 3 years and still working while others fail after 4 months. Send us an email or call us with more details of your application.

Does it display just the volume(gallon/litres) or can it display flow rate(gpm/lpm) as well?
Asked by: akasal
Thank you for your question?
The FTB300 series Micro-Flow meters can display both volume and flow rate.
