Unpacking and Inspection
UNPACKING AND INSPECTION
Upon opening the shipping container, visually inspect the product and applicable
accessories for any physical damage such as scratches, loose or broken parts, or any other
sign of damage that may have occurred during shipment�
OTE:N If damage is found, request an inspection by the carrier’s agent within 48 hours of
delivery and file a claim with the carrier� A claim for equipment damage in transit is
the sole responsibility of the purchaser�
INTRODUCTION
Designed to withstand the demands of the most rigorous flow measurement applications,
the Top Load Turbine Flow Meter is reliable, rugged and cost effective� Originally developed
for the secondary oil recovery market, the Top Load Turbine Flow Meter is an ideal meter for
liquid flow measurement on or off the oil field�
The meter features a rugged 316 stainless steel housing, rotor shaft, and rotor support
assemblies, a Buna-N O-ring, C17-4PH stainless steel rotor, and hybrid ceramic ball bearings
with AMS 5898 duplex stainless steel race and stainless steel retainer�
OPERATING PRINCIPLE
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 meter�

Preinstallation Considerations
ATTENTION
PREINSTALLATION CONSIDERATIONS
All Badger Meter® Top Load Turbine Flow Meters use stainless steel construction materials�
Make sure the operating fluid is compatible with these materials� Incompatible fluids can
cause deterioration of internal components and cause a reduction in meter accuracy�
The measured liquid should be free of any large particles that may inhibit rotation of the
turbine blades� If particles are present, install a mesh strainer upstream before operating
the meter� See Table 1 for strainer recommendations�
Part Number Strainer Mesh Clearance Filter Size
B411-110 60 0�0092 in� 260 μm
B411-120 10 0�0650 in� 1�6 mm
Table 1: Strainer mesh installation details
The preferred plumbing setup is one containing a bypass line (see Figure 2 on page 6)
that allows meter inspection and repair without interrupting flow� If a bypass line is not
used, it is important that all control valves be located downstream of the flow meter (see
Figure 3 on page 6)�
STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN
CAUSE DAMAGE.
DES DOMMAGES PEUVENT ÊTRE PROVOQUÉS EN FRAPPANT UN MÈTRE VIDE AVEC UN
JET D’ÉCOULEMENT DE VITESSE ÉLEVÉE.
Remove any restriction in the flow line that may cause the liquid to flash� If necessary, install
air eliminators so the meter is not incorrectly measuring entrained air or gas�
Badger Meter recommends installation of a minimum length, equal to ten (10) pipe
diameters of straight pipe on the upstream side and five (5) diameters on the downstream
side of the flow meter� Otherwise meter accuracy may be affected� Piping should be the
same size as the meter bore or threaded port size�
Severe pulsation and mechanical vibration affect accuracy and shorten the life of the
meter� If this condition is present, consider using a meter possessing superior resistance to
pulsation and vibration like the Badger Meter QuikSert Inline Flow Meter� Do not locate the
meter or connection cable close to electric motors, transformers, sparking devices, high
voltage lines, or place connecting cable in conduit with wires furnishing power for such
devices� These devices can induce false signals in the meter coil or cable, causing the meter
to read inaccurately�
If problems arise with the meter, consult the "Troubleshooting Guide" on page 11� If further
problems arise, consult the factory�
If the internal components of the meter are damaged, replace them with a turbine meter
repair kit available from Badger Meter� For information pertaining to the repair kits, see
"Turbine Assembly Replacement" on page 8�

1� Check the inside of the ow meter for any foreign material� Make sure the turbine rotor
spins freely prior to installation� Also, check uid lines and remove any debris found�
2� Install the ow meter with the ow arrow, etched onto the exterior of the meter body,
pointing in the direction of uid ow� Though the meter is designed to function in any
position, where possible, install it horizontally with the conduit adapter facing upward�
3� Thread a magnetic pickup into the conduit adapter completely, nger tight without
forcing it�
4� Install conduit or other ttings suitable for the installation area onto the conduit
adapter hub on the ow meter�

OPERATIONAL STARTUP
Follow these steps when installing and starting the meter� After meter installation, close the
isolation valves and open the bypass valve� Allow liquid to flow through the bypass valve
for sufficient time to eliminate any air or gas in the flow line�
MAKE SURE TO SHUT OFF FLUID FLOW AND RELEASE PRESSURE IN THE LINE BEFORE
ATTEMPTING TO INSTALL THE METER IN AN EXISTING SYSTEM.

1� Open the upstream isolating valve slowly to eliminate hydraulic shock while charging
the meter with the liquid� Open the valve to full open�
2� Open the downstream isolating valve to permit the meter to operate�
3� Close the bypass valve to a fully closed position�
4� Adjust the downstream valve to provide the required ow rate through the meter�
OTE:N If necessary, use the downstream valve as a control valve�

Turbine Assembly Replacement
AVERTISSEMENT
TURBINE ASSEMBLY REPLACEMENT
The meter uses wear-resistant moving parts to provide trouble-free operation and long
service life� Designed for easy field service of a damaged turbine assembly, the repair kits
replace only the internal parts, rather than replacing the entire meter� The turbine assembly
uses stainless steel alloy construction materials�
Each repair kit assembly is factory calibrated to provide accuracy throughout the entire
flow range� Each kit is complete and includes a new K-factor, which is the calibrated
number of pulses generated by each gallon of liquid� Recalibration of the monitor or other
electronics use the K-factor to provide accurate output data�

Turbine Assembly Replacement
MPORTANTI
Before installing the new turbine assembly, note that an arrow is cast or engraved on each
component. The arrow indicates the primary flow direction. When reassembled, the arrowheads
must point in the direction of the fluid flow. The arrows must also be oriented in the UP
position on both rotor supports. The magnetic pickup side of the body signifies the UP position.
Performance of repair kit calibration is in the UP position. Reinstalling the repair kit in the UP
position provides continuation of accurate measurements.
1� Shut o the uid ow and release any residual pressure in the line�
2� Remove the wiring from the magnetic pickup�
3� Remove the external retainer ring from the meter� Set it aside for re-use�
4� Unscrew and remove the large retainer nut� Set it aside for re-use�
5� Remove and discard the turbine assembly�
6� Insert the replacement turbine assembly into the meter housing, aligning the cutout in
the assembly with the key in the housing�
7� Screw on the large retainer nut you set aside in step 4� Tighten it enough to clear the lip
in the meter body�
8� Insert the external retainer ring you set aside in step 3� It ts just below the lip in the
meter body�
9� Reconnect the monitor to the magnetic pickup�
