WARNING!

Insure that the line is depressurized

before beginning installation!

Incorrect installation or removal of

meters can result in serious injury or death.

Read the instructions in this guide on the

proper procedures carefully.

• Any person installing, inspecting, or

maintaining a McCrometer owmeter

should have a working understanding of

piping congurations and systems under

pressure.

• Before adjusting or removing any meter,

be certain the system has depressurized

completely.

• Be careful when lifting meters. Meters can

cause serious injury if lifted incorrectly or

dropped.

Flow meters are velocity sensing devices and

are vulnerable to certain upstream disturbances.

Because of this, meters need certain lengths of

straight pipe before and after the meter. These

distances relate to the diameter of the pipe used.

Obstructions can include elbows, valves, pumps,

and changes in pipe diameter. The uneven ow

created by these obstructions can vary with each

system.

Both upstream and downstream distances are

measured from the center of the saddle as shown

below. In a typical installation to achieve ±2%

accuracy the McMag2000 ow meter should be

installed a minimum of ve diameters upstream

from most ow disturbers and two diameters

downstream of the meter, or when used with a

ow straightener, 1.5 diameters upstream and 1

diameter downstream. (Figure 2)

Figure 2. Pipe Run Requirements

Flow Direction

Figure 1. Flow Direction

It is very important to install the ow meter

relative to the ow of the water. The sensor

must face the ow direction

in order for it to make proper

measurements. (Figure 1)

Proper meter installation is the rst step to

ensure excellent meter performance. Follow

these instructions closely. Consult an authorized

service representative or the Factory for any

circumstances encountered which are not

covered in this guide.

All McCrometer products are tested and

inspected during manufacture and prior to

shipping. An inspection should be performed

at the time of unpacking to detect any damage

that might have occurred during shipment.

• All magnetic ow meters are calibrated for a

full pipeline only; if less, the owmeter will

over-measure the ow.

• Although a minimum line pressure is not

necessary for an accurate measurement, a

full pipe is necessary.

• With the meter installed, check the rate-of-

ow indicator. It should be stable to the point

that it can be easily read. Some indicator

movement is normal due to variations in ow.

Erratic movement of the indicator is normally

caused by ow variations and the system

should be checked. Drastic variations in ow

can decrease meter accuracy. If you suspect a

problem with the meter, please contact your

local McCrometer representative.

The McMag2000 has been designed for easy replacement in the eld for Mc Propeller ow meters. When

the existing saddle meter has been removed, follow the basic installation instructions above. The

replacement ow meter will be fully assembled and ready to install.

The McMag2000 is a saddle type meter. It may be

installed directly onto an existing pipe. Follow

these steps for a new ow meter installation.

1. Cut or hole-saw a round hole minimum 3” in

diameter in the pipe and remove all burrs,

slag, and rough edges from the inside and

outside of the cutout section.

2. Loosen and remove the nuts and washers

from the straps. Remove the straps from the

saddle.

3. Apply lubrication to the gasket and inner

diameter of U-bolts with MolyKote lubricant

or equivalent.

4. Place saddle with gasket in place over the cut

out.

5. Place U-bolts underneath the pipe and

through the saddle clips.

6. Place the provided washers and nuts on the

U-bolts that have been installed through the

saddle clips.

Replacing an Existing Saddle Meter

Basic Installation Steps

7. Start tightening down the nuts evenly in a

gure 8 pattern.

7a. Tighten the nuts to 40 ft. lbs. evenly

using a gure 8 pattern.

7b. Tighten the nuts to 60 ft. lbs. evenly

using a gure 8 pattern.

7c. Tighten the nuts to 80 ft. lbs. evenly

using a gure 8 pattern.

8. Go back around and loosen all of the nuts.

Do not back the nuts completely o of the

U-bolts. The goal is to release force and

tension o of the saddle and the gasket.

9. Repeat steps 7a through 7c exactly as

described. Any step that is skipped may

result in an improper seal.

10. Apply pressure/turn on pump.

11. Verify the saddle is not leaking water. If it is,

repeat steps 5 through 7 until the saddle has

sealed.

The McMag2000 should not be connected to any earth ground. Connecting to an earth ground

may adversely aect meter performance.

The McMag2000 can be used to replace existing 4” to 12” Mc Propeller saddle meters. The

meter CANNOT be used to replace a Water Specialties bolt on saddle meter.

To save battery life, always close the lid after reading the display. If the lid is kept open, the

display will remain on, reducing battery life. If the lid is lost, contact the factory immediately

for a replacement.

The McMag2000 converter display is light activated and requires a minimum amount of

light to appear. Environments where light is low, such as in dimly lit buildings or outdoors

after sundown may prevent the display from appearing when the lid is raised. There is an

optical sensor embedded in the display located under the McCrometer “swirl”logo at the lower

left. If the display does not appear, a ashlight will provide sucient light to bring it up.

NOTE

The display is activated when the lid is opened. (Figure 6) The display will remain active for 30 seconds.

The screen will automatically deactivate after 60 seconds. See Figure 7 below for display descriptions

and symbols.
