Model 210 – HotWater
Installation & Operation
GENERAL
The red Niagara Series WPX turbine flowmeters are ideal for the measure-
ment of water up to 250°Fin commercial and industrial applications.These
high performance meters are unsurpassed in the market place today.
INSTALLATION
The Niagara Series WPX turbine meter may be mounted in a horizontal or
vertical pipe, but never with the register on the bottom.
In order to have accurate measurement, the meter must have 5 pipe
diameters upstream and 3 pipe diameters downstream of straight uninter-
rupted pipe.
The WPX turbine must be placed in a pipeline free of scale, sediment, and
debris. If there is excessive sediment in the pipeline, protect the meter by
putting a strainer (20 mesh) upstream of the meter.
OPERATION
Air must be evacuated from the WPX turbine before operating. Slowly open
valve to let water into the meter. Gradually increase the flow rate to drive out
the air.If the meter is not filled slowly, the surge of water can damage the
measuring elements.

Model 210 Maintenance
REGISTER REMOVAL
Model 210
Totalizer with Reed Switch and InfraredTransmitter
1. Remove strain relief nut and draw out washer and binding nut.
2.Remove screws from register cover.
3.Remove register cover.
4. Slide reed switch or infrared transmitter out of the dovetail slot in
the register.
5. Remove sealing wire out of sealing segment and working
clamp ring.
6. Pull sealing segment out of ring.
7.Turn working clamp ring and register 90 degrees to the left or the right and
lift off.
8.The register cannot be disassembled further. It is hermetically sealed and
must be replaced as a unit if damaged.
Straight Totalizer
1.Remove the fillister head screws from the register cover and lift
off cover.
2.Remove sealing wire.
3. Lift of sealing segment.
4.Turn clamp ring 90 degrees to the left or the right and lift it up with
the counter.
REMOVING MEASURING CHAMBER
Model 210 – Sizes 2”, 3”, 4”, 6”& 8”
1. Loosen sealing wire.
2. Remove hex head screws.
3. Lift out measuring chamber housing.
4. If measuring unit is stuck, loosen it by prying on the cast recesses with a
screw driver.
5. Check O-Ring for damage.Replace if necessary.
Model 210 – Size 10”
1. Loosen sealing wire.
2.Remove hex screws.
3. Grip measuring chamber housing by the two lifting eye bolts and
lift out.
4. Check O-Ring for damage and wear. Replace if necessary.
INSTALLATION OF MEASURING CHAMBER
Model 210
Install the Model 210 by following the reverse order of the removal instruc-
tions.The following items should be checked:
• O-rings and lip washers should be checked for damages before installation.
• Slightly lubricate O-rings and regulator shaft.
• The slot of regulator drive has to be in line with the regulator vane in the
starting position.

GENERAL
Theblue NiagaraSeriesWPX turbine flowmetersareideal forthe measurement
of water up to 120°F
in commercial and industrial applications.These high
performancemeters are unsurpassed in themarketplacetoday.
INSTALLATION
The Niagara Series WPX turbine meter may be mounted in a horizontal or
vertical pipe, but never with the register on the bottom.
In order to have accurate measurement, the meter must have 5 pipe
diameters upstream and 3 pipe diameters downstream of straight uninter-
rupted pipe.
The WPX turbine must be placed in a pipeline free of scale, sediment, and
debris. If there is excessive sediment in the pipeline, protect the meter by
putting a strainer (20 mesh) upstream of the meter.
OPERATION
Air must be evacuated from theWPX turbine before operating.Slowly open
valve to let water into the meter. Gradually increase the flow rate to drive out
the air.If the meter is not filled slowly, the surge of water can damage the
measuring elements.

REGISTER REMOVAL
Model 222
1. Depress the tab in the register box below the hinge. Lift hinged side of
register and rotate forward to remove it from the meter.
2. Remove the sealing tape from the locking segment and register retaining
ring. Remove the locking segment from the retaining ring by prying straight
up on the locking segment with a flat screwdriver.
3. Spread the retaining ring to remove it from the slot on the top case and
remove it. Lift register off top case.
4. To re-assemble, reverse the order of the instructions above.
