Turbine Flow Meter

B16D Series FloClean Sanitary

DESCRIPTION

The FloClean Sanitary turbine flow meter was developed for use
in the food, beverage and pharmaceutical industries. The 316L
stainless steel construction provides a durable and cost efficient
flow measurement system that offers excellent accuracy
and repeatability.

The FloClean uses the most up-to-date polishing technology
on all internal components and all materials comply with FDA
requirements. FloClean B16D Series meters have removable
thrust bearings for ease of cleaning and inspection, and meet
the requirements of 3-A Sanitary Standard number 28-04 for
use in clean-out-of-place (COP) and sanitize-out-of-place (SOP)
applications and carry the 3-A Sanitary symbol.

The FloClean output signal is a sine-wave that is proportional
to volumetric flow. With optional Blancett electronics, FloClean
provides local flow rate and volume totalization and interfaces with
most displays, PLCs and computers.

INSTALLATION

Install the flow meter with the flow arrow, which is etched on the
exterior of the meter body, pointing in the direction of fluid flow.
Install the meter horizontally with the magnetic pickup facing
upward. For optimum performance, the flow meter should be
installed with a minimum of 10 diameters upstream straight pipe
length and 5 diameters downstream straight pipe length.

REPAIR KITS

Factory calibrated replacement kits are available for field or factory
service. Both of the FloClean models are designed to allow for quick,
easy disassembly and replacement of internal components. The
repair kit contains two retaining rings, two rotor supports, one rotor
assembly and a K-factor tag.

OPERATING PRINCIPLE

Fluid entering the meter first passes through an inlet flow straightener that reduces its turbulent flow pattern. Fluid then passes through
the turbine, causing the turbine to rotate at a speed proportional to fluid velocity. As each turbine blade passes through the magnetic field
generated by the meter’s magnetic pickup, an AC voltage pulse is generated. These pulses provide an output frequency that is proportional
to volumetric flow.

KFACTOR

The K-factor represents the number of output pulses transmitted per gallon of fluid passing through the turbine meter. Each turbine has a
unique K-factor. However, turbine meters are not functionally consistent throughout the full flow range of the meter.

There are several forms of friction inherent in turbine meters that slow down the rotational movement of the turbine rotor. These frictional
forces include: magnetic drag, created by electromagnetic force of pickup transducers; mechanical drag, due to bearing friction; and viscous
drag, produced by flowing fluid.
See charts below.

As flow increases, the frictional forces are minimized and the free-wheeling motion of the turbine rotor becomes more linear (proportional
to flow). The K-factor becomes relatively constant and linear throughout the balance of the linear flow range. This is approximately a 10:1
turndown ratio from the maximum flow rate down to the minimum flow rate.
