Badger Meter QuikSert - Manual (Page 5)

INTRODUCTION
The Explosion-Proof QuikSert turbine flow meter was developed for liquid applications where accuracy and dependability
are of concern to the operator . QuikSert's 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 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 .
