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.

NOTE

The McMag2000 can be used to replace existing 4”to 16”Mc Propeller saddle meters. The meter

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

6. Remove the ProCommGo converter lid by

loosening the four captive screws at each

corner until the lid can be lifted from the

converter enclosure base.

7. Loosen the two captive screws that secure the

unhinged end of the internal bracket from

the lower converter housing. The internal

bracket (which holds the main circuit board

and battery pack) should now swing freely

over to one side, thus exposing the bottom

of the converter enclosure base, large pass

through and four mounting holes.

8. Place the lubricated O-ring (#3) into the

groove on top of the adapter plate (#4) and

mount the base plate of the ProCommGo

converter onto the adapter plate with the

four mounting screws (#5.1), lock washers

(#5.2), and at washers (#5.3).

9. Insert Ethernet cable assembly (#2) down

through the bushing (#6.1) and ell until the

Ethernet plug end extends 2-3 inches beyond

the threaded portion of the saddle elbow.

10. Plug the cable into the sensor (#7.1).

11. Push the sensor onto the elbow (threaded

end) until the skirt of the sensor has extended

past the rst O-ring. The sensor should stop

against the threads.

12. Screw the sensor onto the ell. Hand tighten

only. Do not cross thread when attaching

sensor.

Refer to Figure 3 and Figure 4 for the conversion procedure.

Removing the ow meter

1. Remove the ow meter that will be converted to an McMag2000.

2. Remove all parts from the saddle. Keep the saddle, U-bolts and U-Bolt nuts/washers. All other parts

will not be used.

3. Connect the adapter plate (#4) to the saddle with the bushing (#6.1), two O-rings (#6.2 & 6.3), and

gasket (#6.4). Ensure to adequately tighten the bushing (>50ft-lbf) to avoid loosening over time.

4. Replace and lubricate the two O-rings (#7.2) on the threaded end of the ell.

The McMag2000 comes pre-congured from the Factory based on the installation parameters provided

to McCrometer at the time of order. Other than activating the display, there is nothing required of the

user for the basic operation of the ow meter.

Operation

The 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.
