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.

“TF” notication 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 benets with increased pumping.

Turbulent ow tracking allows technicians to apply mathematical cool-

ing principles to all machines in a water system. Visit the Technical

Documents section of www.smartow-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.

Pipe Conguration

For best performance, install a straight run of pipe equal to 10 pipe

diameters on the inlet side of the TracerVMA owmeter and a straight run of

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.

EMI/RFI Interference

Care should be taken to route power and signal cables away from motors

and pumps. Signal integrity may be adversely aected by close proximity

of the wiring to machinery producing high frequency emissions.

BTU Basics

To obtain the most accurate BTU/m calculation, use the

Tracer VMA to measure the supply side water temperature (in °F)

before installing in a cooling water return line.

BTU’s per minute calculation is based on the increase in water temperature

multiplied by the ow rate. The TracerVMA calculates this information

based on supply side temperature entered manually. Due to inherent dier-

ences in most thermometers, the most accurate BTU calculation will result

from using the same thermometer (inside the TracerVMA) to measure supply

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

Cable

Maximum eective signal cable length is 4.8M (16ft)

as supplied. Splicing extra length to the cable is not

recommended.

Flow and Mounting Direction

Orient the TracerVMA User Interface so the ow

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

TracerVMA User Interface.

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.
