DESCRIPTION AND USE
Cox Precision Turbine Flow Meters are a precisely manufactured and calibrated instruments used in accurate rate-of-flow and
total-flow measurement of all types of fluids, whether liquid or gas.
They also have many applications as sensors in process flow control.
The flow meter mounts directly in the flow line and consists of a cylindrically bored housing, a flow straightener and turbine
assembly, and magnetic or carrier frequency pickoffs, as shown in Figure 1.
On all Precision Flow Meters, the magnetic or carrier frequency pickoff is located directly above the turbine, near the
downstream end of the flow meter. The flow straightener and turbine assembly is retained in the housing by a snap ring and
can be easily removed for cleaning and further disassembly.
Figure 1: Turbine flow meter
Cox Precision Turbine Flow Meters are provided with flow straighteners at the downstream and upstream ends. The flow
straighteners diminish any turbulence created by the turbine. Other physical differences are illustrated in exploded views. See
Figure 2 and Figure 3.
Fluid passing through the meter causes the rotor and bearing to revolve at a speed directly proportional to fluid velocity.
As each rotor blade passes the pickoff, it varies the pickoff’s reluctance, producing an output signal. Since turbine speed is
directly proportional to fluid velocity, signal frequency is similarly proportional to the volumetric rate-of-flow. The output
signal can be fed into various types of instruments to indicate the rate-of-flow, such as indicators, frequency converters,
counters, recorders and controllers.
Cox uses two pickoff technologies, magnetic and carrier frequency (RF). The magnetic pickoff has a self-generating mV
frequency output. The RF carrier pickoff senses eddy current losses as the rotor blade passes the pickoff. It does not use an
internal permanent magnet and therefore eliminates magnetic drag on the rotor. This results in linear flow ranges up to 100:1
and repeatable operating flow ranges up to 150:1. The RF carrier pickoff requires a signal conditioner to generate an output. A
high level signal offers the advantage of high output signal to noise ratio over the entire range of the flow meter and permits
long distance signal transmission.
All Cox Precision Turbine Flow Meters are designed to provide a high frequency output voltage at the maximum of their
flow range. This high frequency signal improves resolution and standardized output permits several overlapping range flow
meters to be connected in series to one indicating instrument. Data concerning extended ranges, specific output voltage
and other frequency ranges is available from the Badger Meter Sales Department. As with any precision instrument, the full
capabilities of the Cox Precision Turbine Flow Meter can be realized only through close adherence to the installation and
maintenance instructions discussed in this manual.

INSTALLATION
Meter Orientation
Cox Precision Turbine Flow Meters may be installed in any position without affecting performance. Be sure direction of flow is
in the direction of the arrow engraved on the flow meter body. Exception: Position gas service meters as calibrated.
Piping
Recommended layout for Cox Precision Turbine Flow Meters specifies a straight section of pipe or tube in the same size as the
flow meter and equal in length to 10 diameters on the upstream side, and a similar section equal in length to 5 diameters in
order to retard the formation of swirls in the liquid, which can cause incorrect flow meter output. If space prohibits the use
of these straight sections, use extreme care in arranging the piping to produce as straight and smooth a flow as possible.
Available Cox Flow Straighteners are listed in the Cox Flow Straighteners Product Data Sheet. Go to www.badgermeter.com.
Use of Pipe Compound
The 37-degree flared tube connections of Cox Precision Turbine Flow Meters DO NOT require any sealing compound or Teflon
tape, and none should be used. The use of these on adjacent piping should be held to a minimum in order to avoid coating
the bearings and rotor blades with compound, causing premature rotor failure and erratic performance.
OTE:NCopper conical seals or crush rings may be used, if necessary.
BLEED ALL AIR AND VAPOR FROM THE LIQUID AFTER INSTALLING OR REINSTALLING A FLOW METER.
START FLOW SLOWLY TO AVOID SENDING A “SLUG” OF HIGH VELOCITY AIR OR VAPOR THROUGH THE FLOW METER
AND CAUSING IT TO OVERSPEED. START REQUIRED FLOW AFTER FLOW METER IS FULL OF LIQUID. AERATED LIQUIDS
FLOWING THROUGH A FLOW METER WILL RESULT IN INCORRECT FLOW RATES.
DISASSEMBLY
Cox Precision Ball Bearing Type
1. Firmly hold ow meter and, using tweezers, carefully remove internal snap ring from the upstream end.
2. Use long nose pliers and grasp one vane of ow straightener and gently pull ow straightener and rotor assembly from
the body. Use slight twisting motion. Snug t at transition.
3. Press down on the hub to relieve spring pressure on C-washer and remove with tweezers or thin nosed pliers. Remove
hub, spring and spacer.
4. Carefully remove rotor from shaft.
5. Remove a snap ring from side of bearing and push bearing out of rotor.
OTE:NModels CLFA6 and CLFB6 must be returned to factory for bearing change.
CLEANING
Immerse all parts, except pickoff, in a clean, filtered solvent suitable for removing residue from the liquid the flow meter has
been used with. If necessary, use a soft bristle brush.
If there is foreign matter in the ball bearings, allow them to soak in the solvent for approximately 10 minutes and then dry
with filtered compressed air. Do not use excessive air pressure.
OTE:NDo not sonic clean bearings!
EXERCISE EXTREME CARE DURING THE CLEANING PROCESS SO THAT NONE OF THE PARTS ARE DROPPED,
SCRATCHED OR DAMAGED IN ANY WAY. NO ATTEMPT SHOULD BE MADE TO FURTHER POLISH ANY OF THE PARTS,
ESPECIALLY THE ROTOR.

Procedure for Cleaning a Turbine Meter after Water Calibration and/or Service
OTE:NWhen cleaning flow meters, keep the body, sleeve and pickoff together. Sleeve is fitted to body and pickoff has a
protruding pin. Replacement pickoffs are supplied with a nut and have no protruding pin.
1. Remove the meter from the line and let all excess water drip out.
2. Fill the meter with alcohol (at least 50% Isopropyl, Ethyl or Methyl) and let it stand for 5 minutes.
3. Discard the alcohol and let the meter dry for 2 minutes.
4. Fill the meter with MIL-C-7024 Type 2 calibration uid (or similar solvent) and let it stand for 1 minute.
5. Discard the calibration uid and ush the meter with an approved uorocarbon solvent, such as Isotron.
OTE:NIf this procedure is not possible, the turbine meter should always remain filled with water when not in use, to prevent
internal wetted parts from being exposed to air.

REASSEMBLY
Reassembly is the reverse of disassembly except for the following:
• On Precision Turbine Flow Meters where shaft bearings are provided with a
retainer, always install with the retainer flange facing upstream.
• Inspect rotor for markings as shown in Figure 4 to indicate flow direction before
assembly.
• Flow meters having broached slots in the body for flow straightener vanes
should be carefully assembled.
• Align straightener vanes with the slots and push gently until the assembly
is seated.

TECHNICAL TERMS
Several terms, such as K-Factor and linearity, are used to indicate turbine flow meter performance.
K-Factor
“K” is a letter used to denote the cycles per gallon factor of a flow meter. This factor is a fixed value used in resolving or
totalizing the pulse count output of a flow meter. It results from the equation:
Cycles per second/Gallons per second = Cycles per gallon (K)
Repeatability
The maximum deviation from the corresponding data points taken from repeated tests under identical conditions.
Linearity
This is defined as the deviation from the mean calibration factor (K) and is expressed as being within a certain tolerance. Cox
Precision Turbine Flow Meters are linear to ± 0.5% over the range shown.
CALIBRATION DATA
K-Factor
The calibration data supplied with a Cox Precision Turbine Flow Meter is shown in Figure 6.
Correct application of a Cox Precision Turbine Flow Meter requires consideration of many important factors. Because of
the wide variation of possible applications, detailed data for liquid flow models only is given in this manual. For special
requirements—such as those outside the range of –300…350° F, those with extremely corrosive liquids, gases and other
unusual conditions—consult the Badger Meter Sales Department.
20-Point Calibration
Calibration at twenty flow rates (10 up-scale and 10 down) between minimum and maximum flow range, is available for
application where ± 0.25% accuracy or better is required. With this calibration complete data on signal output, pressure drop,
K-Factor and deviation from linearity is supplied.
30-Point Calibration
This is the same as the 20-point, with 10 extra points to cover the longer range of the carrier type meters.
UVC-Universal Viscosity Curve
A 10-point calibration is made at each of four viscosities if curves of “K” versus Hertz were made. In between, viscosities cannot
be determined (see right side of Figure 5). Replot as “K”versus Hertz divided by centistokes. A single curve is drawn through all
data points. Other viscosity curves can now be determined. Use only over 10:1 range for viscosity effects.
Gas Calibrations
When performed at the Flow Dynamics facility, a curve of ACFM vs. Hertz is supplied.
Pressure Rating
The standard LoFlo and Precision Flow Meters are rated 2500…5000 psi operating pressure. They have a 4:1 pressure safety
factor. Flange flow meters are rated for service pressure according to ANSI ratings for the flanges used.
Operation at temperatures above 200° F will decrease the connection rating because of lowered stress capabilities of
the metal.
