Configuration:
There are several possibilities regarding the measurement of water or steam energy given
the location of the meter and the use of a second RTD. The table below summarizes the
possibilities:
Fluid Meter Location Second RTD Measurement
Water “Sent” Flow Line “Return” Flow Line Change in Energy
Water “Return” Flow Line “Sent” Flow Line Change in Energy
Water “Sent” Flow Line None Outgoing Energy
Steam “Sent” Flow Line “Return” Flow Line (condensate) Change in Energy
Steam “Sent” Flow Line None Outgoing Energy
As above, you must properly configure the meter in the Energy Menu.
1. Loc in Sent Flow? Select Yes or No based on where the meter is located. Refer to the
above table.
2. Heating System? Select Yes for a hot water system used for heating. Select No for a
chilled water system used for cooling. Always select Yes for a steam system.
3. % Returned. Select a number between 0% and 100%. Estimate the amount of water
that returns. It is usually 100%, or can be less than 100% if historical data shows
the amount of makeup water used. If a second RTD is not used, set to 0%. When 0%
is selected, the energy calculation represents the outgoing energy only (no return
energy is subtracted).
i IMPORTANT NOTICE
The meter ships from the factory assuming 0% return and has a 1000 ohm resistor installed in the
RTD #2 wiring location. This needs to be removed if the meter is to be used in a manner other than
with 0% return and with the customer supplied RTD in its place.
