Blancett B253-102 User manual

INTRODUCTION
The QuikSert turbine flow meter is designed with wear-resistant
moving parts to provide trouble-free operation and long service
life. The QuikSert meter repair kit is designed for easy field service
of a damaged flow meter, rather than replacing the entire flow
meter. Repair parts are constructed of stainless steel alloy and
tungsten carbide.
Each turbine meter 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.
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 supplied.

TURBINE METER REMOVAL
HIGH PRESSURE LEAKS ARE DANGEROUS AND MAY CAUSE PERSONAL INJURY. MAKE SURE THAT FLUID FLOW HAS
BEEN SHUT OFF AND PRESSURE IN THE LINE RELEASED BEFORE ATTEMPTING TO REMOVE THE METER.
Disassembly
1. See Figure 1 on page 3 and Figure 2 on page 3 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.
OTE:N Meters 2 inches and larger have retaining screws.
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. Remove the rotor.
6. Remove the retaining ring from the opposite side of the meter.
OTE:N Meters 2 inches and larger have retaining screws.
7. Remove the second rotor support.
Installing the New Kit
MPORTANTI
Before reassembly, note that an arrow is cast or engraved on each component (see note below). The arrow indicates the direction of
flow. The meter must be reassembled with arrowheads pointed in the direction of the fluid flow. The arrows are to be oriented in the
UP position on both rotor supports. The magnetic pickup side of the body signifies the UP position. This is the position at which the
repair kit was calibrated. Use this position for meter accuracy.
Figure 1 on page 3 and Figure 2 on page 3 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 is
provided on the downstream side of the rotor shaft to indicate 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. Be sure that retaining rings are completely installed in each groove.
OTE:N Meters 2 inches and larger will have retaining screws on both ends of the meter (see Figure 2).
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.
OTE:N Meters 2 inches and larger meters will have retaining screws on both ends of the meter (see Figure 2).
5. Check the meter by blowing air through the assembly. If the rotor does not turn freely, disassemble the meter and check
for anything that would obstruct movement of the rotor.
EXCESS AIR PRESSURE MAY DAMAGE THE ROTOR AND BEARINGS BY OVER SPINNING.
6. Install the magnetic pickup.
OTE:N At this time, the electronics will need recalibration. Refer to the product user manual. If you have any questions on
recalibration, contact Badger Meter, Inc. or the manufacturer of the associated electronics.
