Description
Click here if you want to know more about flow meters.
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 minimise 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 minimise 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 connection.
