The Blancett FloClean turbine flow meter is designed with wear resistant moving parts to provide trouble-free operation and
long service life. The durable 316L stainless steel construction provides a cost efficient flow measurement system that offers
excellent accuracy and repeatability. The FloClean turbine meter repair kit is designed for easy field service of a damaged flow
meter, rather than replacing the entire flow meter. See Repair Kits on page 12 for information.
THEORY OF OPERATION
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.

INSTALLATION
THE METER SHOULD NOT BE SUBJECTED TO TEMPERATURES ABOVE 300° F (149° C), OR BELOW –150°F (–101° C) OR
THE FREEZING POINT OF THE METERED LIQUID. HIGH TEMPERATURES WILL DAMAGE THE MAGNETIC PICKUP, WHILE
LOWER TEMPERATURES WILL LIMIT THE ROTATION OF THE ROTOR.
INCOMPATIBLE FLUIDS COULD DETERIORATE INTERNAL PARTS AND CAUSE THE METER TO READ INACCURATELY.
Plumbing
The flow meter must be installed with the flow arrow, etched on the exterior of the meter body, pointing in the direction of
fluid flow. Though the meter is designed to function in any position, it is recommended, where possible, to install horizontally
with the magnetic pickup facing upward.
The liquid being measured must be free of any large particles that may obstruct spinning of the rotor. If particles are present,
a mesh strainer should be installed.
If small particles are present in the fluid, Blancett recommends that a strainer be installed upstream of the meter. See Table 2
for filtration recommendations.

Table 2: Filtration recommendations
Severe pulsation and mechanical vibration will affect accuracy and shorten the life of the meter.
The preferred plumbing setup is one containing a bypass line that allows meter inspection and repair without interrupting
flow. See Figure 3. If a bypass line is not utilized, it is important that all control valves be located downstream of the flow meter.
See Figure 4.

This is true with any restriction in the flow line that may cause the liquid to flash. If necessary, air eliminators should be
installed to ensure that the meter is not incorrectly measuring entrained air or gas.
It is recommended that a minimum length, equal to ten (10) pipe diameters of straight pipe, be installed 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.

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.
DAMAGE CAN BE CAUSED BY STRIKING AN EMPTY METER WITH A HIGH VELOCITY FLOW STREAM.
If problems arise with the flow meter and monitor, consult the TROUBLESHOOTING GUIDE on page 16. If further problems
arise, consult the factory.
If the internal components of the turbine flow meter are damaged, turbine meter repair kits are available. Information
pertaining to the turbine meter repair kits is referenced in Repair Kits on page 12.

Operational Startup
The following steps should be followed when installing and starting the meter.
MAKE SURE THAT FLUID FLOW HAS BEEN SHUT OFF AND PRESSURE IN THE LINE RELEASED BEFORE ATTEMPTING TO
INSTALL THE METER IN AN EXISTING SYSTEM.
1. After meter installation, close the isolation valves and open the bypass valve. Flow liquid through the bypass valve for
sucient time to eliminate any air or gas in the ow line.
2. Open upstream isolating valve slowly to eliminate hydraulic shock while charging the meter with the liquid. Open the
valve to full open.
HIGH VELOCITY AIR OR GAS MAY DAMAGE THE INTERNAL COMPONENTS OF THE METER.
3. Open downstream isolating valve to permit meter to operate.
4. Close the bypass valve to a full closed position.
5. Adjust the downstream valve to provide the required ow rate through the meter.
OTE:NThe downstream valve may be used as a control valve.

Each FloClean 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. This K factor will be used
to recalibrate the monitor or other electronics to provide accurate output data.

Service Procedures
HIGH-PRESSURE LEAKS ARE DANGEROUS AND CAUSE PERSONAL INJURY. MAKE SURE THAT FLUID FLOW HAS BEEN
SHUT OFF AND PRESSURE IN THE LINE RELEASED BEFORE ATTEMPTING TO REMOVE THE METER.
3-A Turbine Disassembly and Cleaning Procedure
OTE:NRefer to Figure 10 for relative positions of repair kit components.
1. Remove the magnetic pickup from the meter body to avoid damage during procedure.
2. Remove the retaining ring from one end of the meter.
3. Keeping the meter upright (pickup port at the top), remove the rotor support from the body, taking care not to rotate it in
the process. If the rotor support is jammed in the body, use a pair of pliers or vice grips to break it free.
4. Hold the rotor support over a suitable container and rotate it through 180°. The thrust ball will drop out. Take care not to
lose the ball.
5. Remove the rotor assembly.
6. Remove the second retaining ring from the opposite side of the meter.
7. Repeat steps 3 and 4 for the remaining rotor support.
8. Identify parts and ow direction to match with original meter body.
9. Clean and/or sanitize parts to meet appropriate sanitary standards.

B16C SERIES COP/SOP 3A TURBINE INSTALLATION
OTE:NThis procedure applies to installation of replacement turbine repair kits and re-installation of cleaned or
sanitized turbine.
MPORTANTI
Before reassembly, note there are weep holes on each rotor support. These weep holes must be facing down toward the bottom of
the meter body when installed.
The meter must be reassembled with the arrowheads on the rotor pointed in the direction of fluid flow. The magnetic pickup
side of the body signifies the up position. This is the position that the repair kit was calibrated, and this is the position to be
used to ensure meter accuracy. Due to the polished surfaces, there are no arrows on the rotor support to indicate which rotor
support is to be placed upstream or downstream. Please install the repair kit as it was received in the box, using the arrow on
the rotor to determine the placement of the rotor support.
1. If required by process procedures, the meter should be cleaned prior to installation into the piping system.
2. Drop a thrust ball into a rotor support through the hole provided in the side. Insert rotor support into the meter body.
Keep the thrust bearing hole pointed upwards to keep the ball in place.
3. Secure a retaining ring in the groove provided. Be sure that the retaining ring is completely installed in the groove.
4. Drop a thrust ball into second rotor support through the hole provided in the side. Locate the rotor in the support sleeve
bearing. Insert rotor support and rotor into the meter body and the rst support sleeve bearing. Keep the thrust bearing
hole pointed upwards to keep the ball in place.
5. Secure the second retaining ring in the groove provided. Be sure that the retaining ring is completely installed in
the groove.
EXCESS AIR PRESSURE MAY DAMAGE THE ROTOR AND BEARINGS BY OVER-SPIN.
6. Check the meter by blowing air through the assembly. If the rotor does not turn freely, the meter should be disassembled
and checked for anything that would obstruct movement of the rotor.
7. Install the magnetic pickup.
OTE:NAfter installing the new repair kit, the electronics will need re-calibration. Refer to the electronics’ installation and
operation manual. If there are any questions on re-calibration, contact Blancett at 1.800.235.1638 or contact the
manufacturer of the associated electronics.
