INTRODUCTION

Fluid entering the meter passes through the inlet flow straightener
which reduces its turbulent flow pattern and improves the fluid’s
velocity profile. Fluid then passes through the turbine blades
causing it to rotate at a speed proportional to the fluid velocity.
As each blade passes through the magnetic field, created at the
base of the pickoff transducer, AC voltage (pulse) is generated in
the pick-up coil (see Figure 1). These impulses produce an
output frequency proportional to the volumetric flow through the
meter. The output frequency is used to represent flow rate and/or
totalization of fluid passing through the turbine flow meter.

TURBINE METER

The FTB-1400 Series Turbine Flow Meter is designed to
withstand the rigorous demands of the most remote flow
measurement applications. The FTB-1400 Series Flow Meter
maintains measurement accuracy and mechanical integrity in the
corrosive and abrasive fluids commonly found in oil field
waterflood project pipelines, in-situ mining operations, offshore
facilities and plant locations. Simple to install and service, it can
operate in any orientation (horizontal to vertical) as long as the

“flow direction” arrow is aligned in the same direction as the
actual line flow. For optimum performance, the flow meter
should be installed with a minimum of 10 diameters upstream
pipe length and 5 diameters downstream pipe length.
