Turbine Flow Meter
Model 1100 Flanged Connections
DESCRIPTION
The Model 1100 turbine flow meter is designed to withstand the
demands of the most rigorous flow measurement applications.
Originally developed for the secondary oil recovery market,
the Model 1100 flow meter is an ideal meter for liquid flow
measurement on or off the oil field.
The meter features a rugged 316 stainless steel housing and rotor
support assemblies, 304 stainless steel flanges CD4MCU stainless
steel rotor, and abrasive-resistant tungsten carbide rotor shaft and
journal bearings. The Model 1100 meter maintains measurement
accuracy and mechanical integrity in the corrosive and abrasive
fluids commonly found in oil field water flood projects and many
industrial applications.
When paired with a Blancett flow monitor, the Model 1100 turbine
meter meets a wide range of measurement requirements. This
makes it ideal for applications such as pipelines, production/
injection fields, mining operations, offshore facilities, and other
industrial applications. For a full list of Blancett flow monitors, see

loss of accuracy
INSTALLATION
OPERATING PRINCIPLE
Fluid entering the meter passes through the inlet flow straightener
that reduces its turbulent flow pattern and improves the fluid’s
velocity profile. Fluid then passes through the turbine, causing
it to rotate at a speed proportional to fluid velocity. As each
turbine blade passes through the magnetic field at the base of the
transducer, an AC voltage pulse is generated in the pickup coil.
These pulses produce an output frequency proportional to the
volumetric flow through the meter.

The Model 1100 turbine meter is simple to install and service. It
operates 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 straight pipe
length and 5 diameters downstream straight pipe length.

STANDARD TURNDOWN APPROX. 10:1
KFACTOR
The K-factor represents the number of output pulses transmitted per gallon of fluid passing through the turbine meter. Each turbine has a
unique K-factor. However, turbine meters are not functionally consistent throughout the full flow range of the meter.
There are several forms of friction inherent in the turbine meters that retard the rotational movement of the turbine rotor. These frictional
forces include: magnetic drag, created by electromagnetic forces of pickup transducers; mechanical drag, due to bearing friction; and
viscous drag, produced by flowing fluid.
As flow increases, the frictional forces are minimized and the free-wheeling motion of the turbine rotor becomes more linear (proportional
to flow). The K-factor becomes relatively constant and the linear throughout the balance of the linear flow range. This is approximately a
10:1 turndown ratio from the maximum flow rate down to the minimum flow rate.
