Introduction
INTRODUCTION
Designed to withstand the demands of the most rigorous flow measurement applications, the Model 1100 turbine flow meter
is reliable, rugged and cost effective . Originally developed for the secondary oil recovery market, the Model 1100 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, CD4MCU stainless steel rotor, and
abrasive-resistant tungsten carbide rotor, shaft, and journal bearings . The Model 1100 maintains measurement accuracy
and mechanical integrity in the corrosive and abrasive fluids commonly found in oil field water flood projects and other
industrial applications .
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 the fluid
velocity . As each turbine blade passes through the magnetic field, the blade generates an AC voltage pulse in the pickup coil
at the base of the magnetic pickup (see
Figure 1
) . These pulses produce an output frequency proportional to the volumetric
flow through the meter . The output frequency represents flow rate and/or totalization of fluid passing through the turbine
flow meter .
