System-10-P1 Manual 10/14 - 0656-9 / 18320 Page 6
GENERAL SPECIFICATIONS
CALIBRATION
Flow meter and temperature sensors are individually
calibrated, followed by a complete system calibration.
Field commissioning is also available.
ACCURACY
Differential temperature accuracy ±0.15° F over calibrated range
Computing nonlinearity within ±0.05%
TEMPERATURE SENSORS
Solid state sensors are custom calibrated using N.I.S.T.
traceable temperature standards.
Current based signal (mA) is unaffected by wire length.
PROGRAMMING
Factory programmed for specic application
MEMORY
Nonvolatile EEPROM memory retains all program
parameters and totalized values in the event of power loss.
DISPLAY
Alphanumeric LCD displays total energy, total ow,
energy rate, ow rate, supply temperature and return
temperature

Specication Sheet or Owner’s Manual for ONICON
Insertion Turbine Flow Meter for the correct number of
conductors
24 ±4 VAC input power: Use PVC jacketed copper cable with
a wire gauge suitable for the length of run and required
maximum current carrying capacity. The installation must
comply with all local, state and federal building codes.
120/230 VAC input power: Use a three wire service with one
wire protective earth ground. The installation must
comply with all local, state and federal building codes.
Note: Specications are subject to change without notice.
