BTU Basics
To obtain the most accurate BTU calculation, use the Tracer
to measure the supply side water temperature (in °F) before
installing the Tracer in a cooling water return line.
BTU’s per minute calculation is based on the increase in water
temperature multiplied by the flow rate. The Tracer Electronic
Flowmeter calculates this information based on supply side
temperature entered manually. Due to inherent differences in most
thermometers, the most accurate BTU calculation will result from
using the same thermometer (inside the Tracer) 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 3.
Turbulent Flow
“TFLOW” notification appears on the display when Turbulent Flow
is likely inside the cooling circuit of the selected size.
Turbulent flow is the mixing and swirling of water inside a cooling
line that provides optimum heat transfer. Water flow rate greater than
the point of Turbulent Flow does not provide a proportional benefit.
Turbulent flow tracking allows technicians to apply mathematical
cooling principles to all machines in a water system. Visit the
Technical Documents section of www.smartflow-usa.com for a
detailed discussion of Turbulent Flow.
Input the percentage of glycol in cooling water (0%, 10%, 20% or
30%) for accurate Turbulent Flow Indication. See Setup Mode option
on page 5. Antifreeze compounds of ethylene or propylene glycol are
sometimes added to cooling waer. Glycol compounds have
substantially higher viscosity than water. As a result, higher flow
rates are required to reach Turbulent Flow when glycol is used.
