The FTB-100 Series of turbine meters have a sealed ball bearing design for high accuracy performance (±½% of reading, not full scale) at an economical cost. The non-metallic bearing retainers minimize friction, thereby allowing these meters to be used with clean fluids that have poor lubricating properties ( i.e.water). Ball bearings also give the widest linear flow range, particularly in larger turbines. Bearing replacement and clean-up are fast and easy, since all internal parts are easily accessible by removing a single nut.

These turbine flowmeters have a low mass rotor design which allows rapid dynamic response, so they can be used in pulsating flow applications. Deflector cones eliminate downstream thrust on the rotor and allow hydrodynamic positioning of the rotor between the cones. This provides wider rangeability and longer bearing life than conventional turbine flowmeters. Integral flow-straightening tubes minimize the effects of upstream turbulence.
FTB-100 Turbine Meters are available with integral signal conditioners (as shown in photo) which provide scaled and unscaled frequencies, 4-20 mA, or 0-5 Volt outputs. Units without integral signal conditioners are supplied with mating connector for two-wire hook-up.

If the flow meter with the signal conditioner is good for Zone 0 as is claimed be the previous answer, why does the data sheet say the signal conditioner only good for Zone 1 and Zone 2?

Asked by: datasheets
According to our specifications the signal conditioner is not rated for Zone 0. Only good for zone 1 and 2.

With the FLSC-C3 microcontroller on the FTB-102, is the analog voltage output ranged over the linear flow range only (i.e. 0.75-7.5 gpm over 1-5V) or ranged over the flow range from 0 (i.e. 0 - 7.5 gpm over 1-5V)? The associated manual was not clear.

Asked by: CollN
The FLSC-C3 is configured to output 1VDC at no flow condition and 5 VDC at maximum flow rate.

Are any of the pins electrically connected with the body of the flow meter or housing the signal conditioner sits in?

Asked by: datasheets
Thank you for your inquiry about this flow meter. The turbine flow meter and signal conditioner are recommended to be purchased as a 'SYS' or system and they are scaled together to be used when received. And the flow meter is connected directly to the signal conditioner.

What is the maximum viscosity for use of a turbine meter

Asked by: MikeF2353
The turbine flow meter has a maximum viscosity noted on the data sheet to be 299 cST (or centiStokes) which is a unit of measure for viscous liquids.
