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

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.

Models 222 Maintenance

Model 222

1. Depress the tab in the register box below the hinge. Lift hinged side of

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.

REMOVING MEASURING CHAMBER
