2.0 SPI MAG MODEL 282L
2.1 Instrument Overview
The SPI Mag Model 282L owmeter combines an innovative sensor with a comprehensive electronics package to
provide accurate ow measurement for full-pipe ow monitoring applications.
The insertable sensor (available for one-inch and two inch taps) uses electromagnetic technology to measure
water velocity. The streamlined, debris-shedding sensor shape allows the SPI Mag to be used under many ow
conditions.
SPI Mag has many features to suit a wide variety of applications, and is easily set up using the keypad and readouts.
Refer to the converter manual shipped with your meter system.
Figure 2. 1” and 2” Sensor with Insertion Hardware
The valves are optional or supplied by the customer, and are shown for illustration only.
NOTE:
The converter and sensor are supplied as a matched system. Verify the system serial numbers on both the
converter and sensor match. This will ensure a properly calibrated system. The System Serial Numbers
begin with MM20##### and are located on the side of the converter and on a tag near the end of the
sensor cable.

Figure 3. 2” and 1” 282L Sensors
NOTE: It is required that the exact inside diameter of the pipe is input into the ow computer for the SPI
Mag to provide accurate ow data.
2.2 Flow Calculation
The velocity measurements provided by the full-pipe sensor are used to calculate ow. Flow (also known as Q, as
the ow rate, or as throughput) is the amount of uid moving through a pipe in a period of time. For example, if
100 gallons of water move past the sensor in one minute, the ow is 100 gallons per minute (GPM).
To calculate the ow, two things are needed: The cross-sectional area of the pipe and the average velocity.
Cross-sectional area is found using the inside diameter of the pipe.
Average velocity is found using the sensed velocity (measured by the sensor). A site calibration is performed
to determine the velocity prole. This allows the owmeter to calculate the average velocity from the sensed
velocity.
Flow is calculated by using the Continuity Equation:
Flow = Average Velocity x Area
2.3 Proling Information
For information about the Proling and Site Calibration, refer to these documents:
• One Inch Full Pipe Sensor Installation and Proling Guide, Lit.# 24510-58.
• Two Inch Full Pipe Sensor Installation and Proling Guide, Lit.# 24510-59.
2.4 Full Pipe Sensors
The full pipe sensor makes use of Faraday’s Law of Electromagnetic Induction to measure water velocity. Faraday’s
Law states:
A conductor, moving through a magnetic eld, produces a voltage.
Because water is a conductor, water moving through a magnetic eld produces a voltage. The magnitude of
the voltage is directly proportional to the velocity of the water. The sensor generates an electromagnetic eld,
creating a voltage in the water. The two velocity electrodes, along with the ground electrode measure this voltage.
A faster water velocity produces a higher voltage. By accurately measuring this voltage, the velocity is determined.

4.4 Sensor Assembly Installation
The sensor assembly uses a compression seal, which keeps the
sensor watertight when the pipe is under pressure. Care must be
taken when installing the sensor, to avoid leaks.
1. Visually inspect all elements of the installation to ensure they
are structurally sound and of high quality materials, including
all welds, couplings and nipples. To prevent future corrosion,
nipples should be high quality stainless steel.
2. Put a generous amount of the pipe sealant (supplied with
the sensor) on the compression seal threads. (Teon tape
may also be used.) NOTE: if pipe sealant gets on the sensor
electrodes the velocity signal may be lost.
3. Place the compression seal threads over the pipe valve. Turn
the entire sensor assembly clockwise to secure the assembly
to the valve.
4. The seal is secure when a large amount of force is required to
turn the assembly. Line up the arrow (on the top plate) with
the direction of the ow.

4.5 Inserting The Sensor
Ensure the compression seal is only hand tightened.
1. Barely crack open the valve and tighten the compression seal as required to minimize leaks. A towel draped
around the compression seal can reduce spray if necessary.
2. Open the valve completely. Failure to open the valve completely will cause the valve to scrape the sensor
during insertions and may result in permanent damage to the sensor.
3. Insert the sensor into the pipe by simultaneously rotating clockwise the two captive nuts on the top plate for
the 2”sensor, and the single captive nut on the 1”sensor. For the two captive nuts on the 2”sensor use the two
ratchet wrenches provided. It is recommended that the sensor insertion tool (p/n 75031) be used to rotate the
captive nuts on the 2”sensor to ensure the top plate compresses evenly. See section 4.8.
4.6 Clean Water Sensor Position
If the ow is clean water the sensor can be placed at
1/8 of the inside diameter. To position the sensor at
1/8 of the ID, follow the instructions below:
• Measure the tube from the top of the cap
to the end of the sensor to nd the tube
length (TL).
• Calculate (1/8 ID): 1/8 ID = 0.125 x Pipe ID
• Add wall thickness to 1/8 ID.
• Calculate distance A: A = TL - (1/8 D + WT)
• Set the top edge of the insertion tube cap distance A from the pipe.

TL
WARNING!
The compression seal/sensor assembly may be under pressure. Serious injury may result if proper
procedures are not followed. Do not attempt to install the sensor without the restraining rods fully
assembled.
IMPORTANT
On the 2” installation hardware, if the captive nuts
are not tightened simultaneously, the top plate will
become crooked and cause the sensor to be inserted
at an angle and may cause permanent damage to the
sensor.

4.8 Sensor Insertion Tool
McCrometer recommends using a sensor insertion tool (P/N 75031)
to help with inserting the sensor and to avoid any damage to the
sensor. Place the proling insertion tool over the captive nuts and
lock it into place with spring locks located on the bottom of the tool.
Using the provided wrench rotate the high gear shaft clockwise
until the bottom of the sensor reaches the far wall of the pipe.
Figure 11. 0.00 Position
4.7 Raw Water Sensor Position
The operation position for raw waste water and sludge is at sensor location 0.00 to prevent debris from collecting
on the sensor and aecting velocity readings. To position the sensor at this location follow the instructions below:
• Calculate distance A by subtracting the pipe wall thickness (WT) and ¾” from length C. See Figure 11 for
Length C (Tube Length).
• Position the top edge of the insertion tube cap distance A from the pipe.
If the ow is clean water, the sensor can be left at the 1/8 D position. Do not leave the sensor in this position
for raw waste water because debris could collect on the sensor and aect the velocity readings. In waste water
applications, position the sensor at location 0.00. See section 4.7.

To remove the sensor follow the steps below:
1. Visually inspect the pipe and entire assembly for damage or corrosion paying close attention to any nipples and
welded couplings. If there is any doubt as to the condition of any element of the pipe or sensor, depressurize
the line before attempting a removal of the sensor.
2. Loosen the compression seal until the seal just begins to leak. This will relieve the pressure on the compression
seal allowing the sensor to be removed. Draping a towel around the compression seal can reduce any spraying
water. NOTE: The compression seal may prevent immediate leakage on sensors installed for a long period of
time until the sensor begins to rise.
3. On the 1” sensor, rotate the captive nut on the top plate to raise the sensor.. On the 2” sensor rotate the
captive nuts on the top plate simultaneously. The sensor insertion tool is recommended. See Section 4.8. This
will cause the sensor to rise out of the pipe. If the line is under pressure do not remove the sensor from the
compression seal completely. Only raise the sensor until it is clear of the valve, but still below the compression
seal. Once the sensor has cleared the valve mechanism, the valve can then be closed. Do not attempt to force
the valve closed while the sensor is still passing through the valve as permanent damage to the sensor can
occur.
4. Once the valve is closed, the entire sensor can be removed from the valve.
5.0 SENSOR REMOVAL
WARNING!
The pipe may be under pressure. Serious injury or death may result if proper procedures are not followed.
!
6.0 MAINTENANCE
The SPI Mag is essentially a maintenance free meter with no user serviceable parts. However, the metered uid may
contain of solids or other contaminants coat the sensor electrodes. A periodic inspection may be recommended
to ensure the sensor electrodes are clean. To clean the unit remove the sensor following all of the instructions
and safety warning contained in Section 5.0. When the sensor is removed from the pipe, carefully wipe down the
sensor with a soft cloth and a mildly abrasive detergent, such as a liquid kitchen detergent.

WARRANTY STATEMENT
Manufacturer warrants all products of its manufacture to be free from defects in workmanship and material
under normal use and service. The warranty for the SPI Mag extends for a period of twenty-four (24) months after
date of shipment, unless altered by mutual agreement between the purchaser and manufacturer prior to the
shipment of the product. If this product is believed to be defective and is within its warranty period, purchaser
shall notify the manufacturer, and will return the product to the manufacturer, postage paid, within twenty-four
(24) months after date of shipment by the manufacturer. If the purchaser believes the return of the product to be
impractical, manufacturer shall have the option, but will not be required, to inspect the product wherever located.
In any event, if the purchaser requests the manufacturer visit their location, the purchaser agrees to pay the non-
warranty expenses of travel, lodging and subsistence for the eld service response. If the product is found by the
manufacturer’s inspection to be defective in workmanship or material, the defective part or parts will either be
repaired or replaced, at manufacturer’s election, free of charge, and if necessary the product will be returned to
purchaser, transportation prepaid to any point in the United States. If inspection by the manufacturer of such
product does not disclose any defect of workmanship or material, manufacturer’s regular service repair charges
will apply. Computing devices sold but not manufactured by McCrometer, Inc. are covered only by the original
manufacturer’s written warranty. Hence, this warranty statement does not apply.
THE FOREGOING WARRANTY IS MANUFACTURER’S SOLE WARRANTY, AND ALL OTHER WARRANTIES,
EXPRESS, IMPLIED OR STATUTORY, INCLUDING ANY IMPLIED WARRANTY OF MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE, ARE NEGATED AND EXCLUDED. THE FOREGOING WARRANTY IS IN
LIEU OF ALL OTHER WARRANTIES, GUARANTEES, REPRESENTATIONS, OBLIGATIONS OR LIABILITIES ON THE
PART OF THE MANUFACTURER.
Purchaser’s sole remedy and manufacturer’s sole obligation for alleged product failure, whether under warranty
claim or otherwise, shall be the aforestated obligation of manufacturer to repair or replace products returned
within twelve months after date of original shipment. The manufacturer shall not be liable for, and the purchaser
assumes and agrees to indemnify and save harmless the manufacturer in respect to, any loss or damage that may
arise through the use by the purchaser of any of the manufacturer’s products.
