INTRODUCTION
The Blancett FloClean turbine flow meter is designed with wear resistant moving parts to provide trouble-free operation and
long service life. The durable 316L stainless steel construction provides a cost efficient flow measurement system that offers
excellent accuracy and repeatability. The FloClean turbine meter repair kit is designed for easy field service of a damaged flow
meter, rather than replacing the entire flow meter. See Repair Kits on page 12 for information.
THEORY OF OPERATION
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.
