Gear flow
meters are suitable for use on virtually any, clean
fluid of medium to high viscosity. As the fluid
passes through the meter is causes two
inter-meching circular gear wheels to rotate. As
the gear wheels rotate a small amount of fluid is
trapped between the gears. Because this volume of
fluid is known a K-Factor (number of pulses per
litre) can be calculated and used to derive flow
rate and total. The volume of fluid transported
with each gear tooth is very small, so the K-factor
for gear flow meters tends to be very high,
providing exceptional resolution and accuracy.
Gear flow meters
are available in aluminium, carbon steel and
stainless steel with either hard metal bearings or
ball bearings for lubricating fluids. Flow rates
from as low as 0.005 L/min and as high as 1000
L/min can be catered for, as well as pressure up to
690 bar.
Standard
configuration is with a square wave pulse output,
options are available for 4-20mA analogue output,
dual pickup for direction sensing and ATEX approval
for use in hazardous areas.
GFM's have
applications in measuring, or the precisely
controlled metering of various pastes and liquids,
ranging from mineral and synthetic oils and greases
to waxes, paints, chemical slurries and
detergents.
