The FTB-1300 Series of turbine flow
meters are designed for industrial
and laboratory measurement of
water, solvents and other low
viscosity fluids. The FTB-1300
Series turbine flow meters feature
a 316 stainless steel body and a
tungsten carbide bearing. They
offer good accuracy and reliability
with very little pressure drop. The
standard turbine flow meters feature
threaded end connections.

The FTB-1300 series of turbine
flow meters is designed with a wear
resistant rotor assembly to provide
trouble free operation and a long
service life. Fluid moving through
the flow meter causes the rotor to
turn at a speed proportional to the
flow rate, and as the rotor blades
cut through the magnetic field of
the pickup, an electronic pulse is
generated. The pulse train is used
to represent the actual flow or total
amount of fluid passing through the
flow meter. The number of
electronic pulses generated per
unit volume is known as a K-factor.
The value is constant over each
flow meter’s operating range, and
is unique to each meter.
