Introduction
Turbine Rotor
Signal
INTRODUCTION
Designed to withstand the demands of the most rigorous flow measurement applications, the Model 1100 Explosion-proof
turbine flow meter is reliable, rugged and cost effective. Originally developed for the secondary oil recovery market, the
Model 1100 Explosion-proof meter is an ideal meter for liquid flow measurement on or off the oil field.
The meter features a rugged 316 stainless steel housing and rotor support assemblies, CD4MCU stainless steel rotor, and
abrasive-resistant tungsten carbide rotor, shaft, and journal bearings. The Model 1100 Explosion-proof meter maintains
measurement accuracy and mechanical integrity in the corrosive and abrasive fluids commonly found in oil field water flood
project and many industrial applications.
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 turbine
flow meter.

1. Check the internals 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 on 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. Secure with a lock nut,
if supplied.
4. Install conduit or other ttings suitable for the installation area onto the conduit adapter hub on the ow meter.

Installation
All Badger Meter Model 1100 Explosion-proof turbine meters use stainless steel and tungsten carbide 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 flow meter. See Table 1 for strainer recommendations.

Table 1: Strainer mesh installation details
The preferred plumbing setup is one containing a bypass line (see Figure 3) 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 4).
STRIKING AN EMPTY METER WITH HIGH VELOCITY FLOW STREAM CAN CAUSES DAMAGE.
ATTENTION

ÉLEVÉE.
This is true with any restriction in the flow line that may cause the liquid to flash. If necessary, install air eliminators to ensure
that 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 flow meter possessing superior resistance to pulsation and vibration like the Badger Meter QuicSert. Do not
locate the flow 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 flow
meter coil or cable, causing the meter to read inaccurately.
If problems arise with the flow meter, consult the on page 11. If further problems arise, consult the factory.
If damaged replace the internal components of the turbine flow meter with a turbine meter repair kit available from
Badger Meter. For information pertaining to the repair kits, see Turbine Replacement on page 8.

Turbine Replacement
TURBINE REPLACEMENT
The Model 1100 Explosion-proof turbine flow meter uses wear-resistant moving parts to provide troublefree operation and
long service life. Designed for easy field service of a damaged flow meter, Model 1100 Explosion-proof repair kits replace only
the internal parts, rather than replacing the entire flow meter. Repair parts use stainless steel alloys and tungsten carbide
construction materials.
Each repair kit is factory calibrated to ensure 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 uses the K-factor to provide accurate output data.
OTE: N If the meter repair kit part number ends in NCC (no calibration), it was not factory calibrated. For these repair kits, use
the nominal K-factor.

Disassembly
1. Refer to Figure 7, Figure 8 and Figure 9 for relative positions of repair kit components.
2. Remove the magnetic pickup from the meter body to avoid damage during repair.
3. Remove the retaining ring from one end of the meter.
4. Remove the rotor support from the body. If the rotor support is jammed in the body, use a pair of pliers or vise-grips to
break the rotor support free.
5. The rotor may also be removed at this time.
OTE: N 4 in. and larger meters have two retaining rings (one on either side of the rotor) that require removal before the rotor
can be removed (see Figure 9).
6. Remove the retaining ring from the opposite side of the meter.
7. Remove the second rotor support.

MPORTANTI
Before reassembly, 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. Reinstallation of the repair kit in the up position ensures continuation of accurate measurements. Figure 7, Figure 8, and
Figure 9 show the proper alignment and orientation of the repair kits.
OTE: N Fractional size (3/8 in., 1/2 in. and 3/4 in.) rotors do not contain a cast or engraved arrow. However, a colored cap on
the downstream side of the rotor shaft indicates flow direction. Remove this cap before assembly, noting
flow direction.
1. Install one of the rotor supports into the body bore, noting the orientation of the arrow.
2. Secure a retaining ring in the groove provided. Check for complete installation of retaining rings in each groove.
OTE: N 4 in. and larger meters have a retaining ring at both ends of the rotor (see Figure 9).
3. Insert the rotor and second rotor support in the opposite side of the body, noting the orientation of the arrow.
4. Secure the second retaining ring in the opposite groove, using the same procedure as in step 2 above.
EXCESS AIR PRESSURE MAY DAMAGE THE ROTOR AND BEARINGS BY OVER SPINNING.
ATTENTION
LA PRESSION ATMOSPHÉRIQUE EXCESSIVE PEUT ENDOMMAGER LE ROTOR ET LES ROULEMENTS PRÈS AU-DESSUS DE
LA ROTATION.
5. Check the meter by lightly pung air through the assembly. If the rotor does not turn freely, disassemble the meter and
remove anything that might obstruct movement of the rotor.
NOTE: At this time, electronics require recalibration. Refer to the display's user manual. If there are any questions on
recalibration, contact us or the manufacturer of the associated electronics.
6. Install the magnetic pickup.
