Installation & Operation Manual
The “Zero Temp Diff” is a very powerful feature in this product which allows any inaccuracies of drift in the temperature
sensors, or 340 temperature measurements to be cancelled out.
This correction can be either manually typed in or if the temperature sensors are known to be at exactly the same
temperature, the “Zero Temp Diff” button can be used to automatically zero the difference between the two readings. To
correct for any erroneous entries, simply manually type 0.0 in both fields.
This is a very powerful feature, but must be used with caution. If used incorrectly, the temperature readings will be incorrect
and the energy rates and totals will also be in error.
Energy Calculation
Figure 25: Rate and Total Units
Select the units of measure for energy rate and total from the Pull-Down menu.
Filter Coefficients
Figure 26: Filter Coefficients
For most applications leave the default setting of 5. If the Flow rate or Energy Rates are some reason unstable (from a
disturbed flow profile for example). This value can be increased as needed.
Pulse Output
Flow or Energy
The Pulse Output can represent either Flow or Energy. Units will be the same as selected in the previous sections.
Pulse width, and pulse resolution will be selected based on the requirements of the receiving device, and system
requirements.
