Description
Page 6 June 2016TRB-UM-01789-EN-02
DESCRIPTION
Blancett B1500 flow meters are precisely manufactured and calibrated instruments used in
accurate rate-of-flow and total-flow measurement.
The flow meter mounts directly in the flow line and consists of a cylindrically bored
housing, a flow straightener and turbine assembly, and a magnetic pickup, as shown in
Figure 1.
The magnetic pickup 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
Blancett B1500 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 1.
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 pickup, it varies the pickup’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, such as indicators, frequency
converters, counters, recorders and controllers to indicate the rate-of-flow.
The Blancett B1500 flow meter is designed to provide a high frequency output voltage
at the maximum of their flow range. This high frequency signal improves resolution and
the 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 factory.

Installation
Page 7June 2016 TRB-UM-01789-EN-02
INSTALLATION
1. Check the ow meter internally for foreign material and make sure the turbine rotor
spins freely prior to installation.
2. Install a minimum of 10 pipe diameters of straight pipe or tube in the same size as the
ow meter on the upstream side, and 5 diameters on the downstream side to avoid
creating turbulence in the liquid, which can cause incorrect ow meter output. If space
prohibits the use of these straight sections, install the piping to produce as straight and
smooth a ow as possible.
3. Flush the ow metering pipe line. Debris such as dirt, grease, piping compounds, weld
slag, rust, shavings and the like could be unknowingly contained within the diameter
of the piping system. Failure to remove these contaminants may damage the internal
components of the ow meter and other system components.
4. Install the ow meter with the ow arrow, etched on the exterior of the meter body,
pointing in the direction of uid ow.
5. Install a mesh strainer upstream before operation of the ow meter if particles are
present. See “Filtration Recommendation” on page 13.
BLEED ALL AIR AND VAPOR FROM THE LIQUID AFTER INSTALLING OR REINSTALLING A
FLOW METER.
6. Start ow slowly to avoid sending a“slug”of high velocity air or vapor through the ow
meter and causing it to over-speed. Start required ow after ow meter is full of liquid.
Aerated liquids owing through a ow meter will result in incorrect ow rates.
7. The pipe containing the ow meter should be completely lled at all times to avoid
corrosion. If a process shutdown is required where the pipe is partially or fully empty,
remove and clean the meter. See “Cleaning” on page 8.
OTE:NThe meter is not recommended for long periods of over-speeding. Over-speeding
increases the amount of pressure drop across the meter and significantly reduces
the life of the bearing and rotor assembly. The maximum amount of
over-speeding for any given meter is 150% of its capacity.

Disassembly
Page 8 June 2016TRB-UM-01789-EN-02
DISASSEMBLY
1. Firmly hold the ow meter and, using
tweezers, carefully remove internal snap
ring from the upstream end.
2. Use long nose pliers to grasp one vane of
the ow straightener and gently pull the
ow straightener and rotor assembly from
the body. Use a slight twisting motion.
3. Press down on the hub to relieve spring
pressure on the C-washer and remove with
tweezers or thin-nosed pliers.
4. Remove hub, spring and spacer.
5. Carefully remove the rotor from the shaft.
6. Remove the snap ring from the side of
the bearing and push the bearing out of
the rotor. Figure 2: B1500 turbine flow meter
CLEANING
Immerse all parts, except the pickup, in a clean, filtered solvent suitable for removing
residue from the liquid used with the flow meter. If necessary, use a soft bristle brush.
If there is foreign matter in the ball bearings, soak the bearings 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 the bearings.
EXERCISE EXTREME CARE DURING THE CLEANING PROCESS SO NONE OF THE
PARTS ARE DROPPED, SCRATCHED OR DAMAGED IN ANY WAY. DO NOT ATTEMPT TO
FURTHER POLISH ANY OF THE PARTS, ESPECIALLY THE ROTOR.
Cleaning a Turbine Meter after Water Calibration and/or Service
OTE:NWhen cleaning flow meters, keep the body, sleeve and pickup together. The
sleeve is fitted to the body and the pickup has a protruding pin. Replacement
pickups 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.

Reassembly
Page 9June 2016 TRB-UM-01789-EN-02
OTE:NIf this procedure is not possible, make sure the turbine meter is always filled with
water when not in use, to prevent internal wetted parts from being exposed to air.
DO NOT INTERCHANGE FLOW METER PARTS OTHER THAN BEARINGS AND
RETAINING RINGS. THIS PRECAUTION IS NECESSARY TO PRESERVE LINEARITY AND
REPEATABILITY.
REASSEMBLY
Reassembly is the reverse of disassembly except for the following:
• On flow meters where shaft bearings are provided
with a retainer, always install with the retainer
flange facing upstream.
• Inspect the rotor for markings as shown in Figure 3
to indicate flow direction before assembly.
• Flow meters that have broached slots in the
body for flow straightener vanes should be
carefully assembled.
• Align the straightener vanes with the slots and push
gently until the assembly is seated. Figure 3: Scribed lines

Page 11June 2016 TRB-UM-01789-EN-02
K-Factor
The calibration data supplied with a B1500 flow meter is shown in Figure 4. Correct
application of a B1500 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, consult the factory.
Pressure Rating
Flange flow meters are rated for service pressure according to ANSI ratings for the flanges
used. Operation at temperatures above 200° F (93° C) decreases the connection rating
because of lowered stress capabilities of the metal.

RECALIBRATION
• Recalibration is not necessary following a cleaning operation or the replacement of
bearings, snap rings, springs or spacers.
• Recalibrate the flow meter if the rotor hub, or rotor and flow straightener assembly
is replaced.
• Flow meters may be recalibrated by the user if the facilities are available, or they may
be returned to the factory. Yearly calibration is recommended.
• When the flow meter is set up for recalibration, allow the fluid to circulate for 5
minutes before beginning the calibrating runs.
