Greetings,
In the last edition of CI-Turbine Talk, we introduced you
to Meinecke's Flanged Turbine Meters... Available in sizes
ranging from 2" to 12". But what about
applications for line sizes 2" and under?
Introducing GPI Industrial Grade Turbine Meters!

GPI's
G2 Series Turbine meters offer you a durable, compact,
high precision fluid measurement systems at a fraction
of the price you'd expect to pay for comparable systems
with similar features and benefits.
By combining a turbine and a basic flow sensing
device with a direct-mounted, microprocessor-based
computer, the entire system is incorporated into one
device which is FM Approved for Intrinsically Safe Class
1, Division 1 uses.
Five turbine sizes designed to address specific
flow ranges:
1/2", 3/4", 1", 1-1/2" and 2".
Connection Options:
NPT, ISO, 150lb ANSI Flange, Tri-Clover
Material options include:
PVC, Brass, Aluminum, CPVC and Stainless Steel

GPI
Commercial Meters are identified by an A1 prefix.
Commercial grade meters are packaged as a self-
contained unit. Select this meter when you need an
accurate, basic meter. GPI Commercial Meters come in
Aluminum and Nylon.
Choose one of the three sizes of Aluminum meters for
petroleum products. Use the Nylon meters for water or
non-aggressive chemicals.

Introducing
the newest members of the GPI Flow Meter line-up... the TM-Series
. Once available only in a 2" line size, this
economical flow meter is now available in 1/2",
3/4", 1", 1 1/2" and 2" sizes. Designed
for water use, these meters are an economical
alternative to the other types of meters. They are easy
to install, just glue into place using primer and
solvents approved for PVC gluing.
Field Calibration allow the user to change units of
measure and to improve accuracy using field conditions.
Whey properly used , these meter are virtually maintenance
free. Batteries can be changed while the meter is in
place. Lithium batteries provide approximately 9,000
hours of use.
Meter Specifications
*Batch & Cumulative Total Displays
*Rate of Flow Display
*Factory Calibration in Gallons or Liters
*Fitting Type: Slip - Schedule 40
*Max Working Pressure: 150 PSIG @ 73'F

How
does a turbine work?
As liquid passes through the meter's flowtube, it turns
an impeller blade which in turn generates an electrical
pulse. This pulse is then converted to a frequency
output proportional to the flow rate. That signal can
then converted at the meter to local rate and total
display or transmitted to a remote location.
What are the best applications for a Turbine
Meter?
The ideal application for a turbine meter would be those
measuring clean, low viscosity fluids in a process where
local and/or remote indication of both rate and total
are required. Turbines are capable of accurately
measuring liquids with higher viscosity as long it
remains relatively stable. Suggested applications
include: Water, Fuels, Juices and Chemicals - both mild
& highly aggressive just to name a few.
How Does Viscosity affect a turbine meter?
Turbine meters are viscosity sensitive. As the viscosity
increases, drag forces on the rotor blades increase, the
low flow response drops off and the linearity of the
meter begins to suffer.
What about installation considerations?
As a rule of thumb, most turbines require straight,
unobstructed runs of 10 pipe diameters upstream and 5 on
the downstream side. Unlike a Variable Area Flowmeters,
Turbines can be installed either vertically or
horizontally, but... they need to be installed such that
the meter/pipe are constantly full.
