BTU Basics
To obtain the most accurate BTU/m calculation, use the
Tracer
before installing in a cooling water return line.
to measure the supply side water temperature (in °F)
VMA
BTU’s per minute calculation is based on the increase in water temperature
multiplied by the ow rate. The Tracer
calculates this information
VMA
based on supply side temperature entered manually. Due to inherent dierences in most thermometers, the most accurate BTU calculation will result
from using the same thermometer (inside the Tracer
) to measure supply
VMA
and return line temperatures. Record the supply side temperature and enter
it using the “Set BTU/m Input Temperature” instructions on page 5.
Turbulent Flow
“TF” notication appears on the display when Turbulent Flow is likely
inside the cooling circuit of the selected size.
Turbulent ow is the mixing and swirling of water inside a cooling line
that provides optimum heat transfer. Water ow rate greater than the point
of Turbulent Flow provides diminishing benets with increased pumping.
Turbulent ow tracking allows technicians to apply mathematical cooling principles to all machines in a water system. Visit the Technical
Documents section of www.smartow-usa.com for a detailed discussion of
Turbulent Flow.
Input the percentage of glycol (0, 10, 20 or 30% only) in cooling water for
accurate Turbulent Flow Indication (default value is 0). See Setup Mode
option on page 5. Antifreeze compounds of ethylene glycol are sometimes
added to cooling water. Glycol compounds have much higher viscosity
than water. As a result, higher ow rates are required to reach Turbulent Flow
when glycol is used.
Cable
Maximum eective signal cable length is 4.8M (16ft)
as supplied. Splicing extra length to the cable is not
recommended.
Flow and Mounting Direction
Orient the Tracer
User Interface so the ow
VMA
direction of the process uid matches the directional
arrow on the body of the meter. Flow in the opposite
direction of the arrow will yield inaccurate voltage
output. The presence of air bubbles in the process uid
will also create an inaccurate voltage output.
Install AutoReg module downstream from the User
Interface at least 5 pipe diameters from the sensor
outlet. Flow regulator response time will increase in
relation to distance between AutoReg module and
Tracer
User Interface.
VMA
Maintenance Instructions
Copper Plumbing Alert
DO NOT connect an aluminum body owmeter
directly to copper plumbing. Galvanic corrosion is very
likely to occur. Stainless steel body material is strongly
recommended for this application.
Pipe Conguration
For best performance, install a straight run of pipe equal to 10 pipe
diameters on the inlet side of the Tracer
owmeter and a straight run of
VMA
pipe equal to 5 pipe diameters on the outlet side of the owmeter.
Use appropriate pipe sealant to prevent leakage on inlet and outlet sides of
the owmeter.
Power
Attach the power and switching connections to the bare wires of the cable
according to the chart at right. Individual wires are 24AWG stranded
copper. Attach 24VDC power to the unit for correct operation.
In normal operation, the internal relay is energized. If power to the unit is
lost, or if unit is turned o, relay state changes to signal an alarm.
Power supply other than 24VDC may damage the electronics! Ensure
that power supply provides Earth Ground (0V) and not a reference.
Earth Ground is required for reliable ow and temperature outputs.
EMI/RFI Interference
Care should be taken to route power and signal cables away from motors
and pumps. Signal integrity may be adversely aected by close proximity
of the wiring to machinery producing high frequency emissions.

Users should not make changes within Calibration Mode.
Accidental loss of factory calibration may occur.
User Mode
Press to enter User Mode. User Mode is display only.
Press r or s buttons to scroll through displays of Flow Rate, Temperature and Reynolds
Number. Totalizer and BTU/m display are available when enabled.
BTU/m is automatically disabled until input temperature is entered within User Mode.
Totalizer function is o when shipped. See Setup Mode instruction to enable and zero Total
Volume display. When totalizer is enabled, total ow volume will be visible on all User Mode
screens. When the display is o, totalizer does not add to the total volume.
Battery Life Indicator in upper right corner of the display may ash on this model but will turn
o automatically. It has no function on this model.
To exit User Mode, press to power down the meter.
