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
