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.
