INTRODUCTION
The QuikSert® explosion-proof turbine flow meter was developed for liquid
applications where accuracy and dependability are of concern to the operator� The
QuikSert stainless steel body incorporates a helical turbine with tungsten carbide
shaft and bearings� It provides an efficient, long service life and a cost-effective
solution for your measurement requirements�
Simple in design and construction, QuikSert uses modified upstream and
downstream flow straighteners for a high degree of flow accuracy� Its between-
the-flange design eliminates the need for mating flanges, requiring less space in
the flow line, lowering costs and providing easy, one-man installation�
The meter produces a sine wave signal proportional to its volumetric flow rate�
With optional Blancett electronics, QuikSert provides local flow rate and volume
totalization and will interface with most instruments, PLCs and computers�
OPERATING PRINCIPLE
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, 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
)� 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�
