INSTALLATION AND CALIBRATION
The UFT-1 transmitter can be mounted in any position. The
optional watertight enclosure provides a watertight seal
against contaminants. While field calibration is not required
with the UFT-1, flow conversion must be accomplished at the
monitoring computer. The information below is provided for
making the conversion calculations.
FLOW RATE
Flow (gpm) = (mA measured - 4 mA) x Maximum gpm
16
Maximum gpm is the flow rate at 20 mA output on the trans-
mitter and must be specified at the time the UFT-1 is ordered
for proper calibration.
TOTALIZED FLOW
Totalized Gallons = (Flow Factor) x (Output Divider) x (Total
Pulses)
For totalized m3, multiply the above by 0.00379.
Output Divider = 10 or 100 depending on jumper-selection.
Flow factors per pulse are shown in the table at the right.

Notes
1. Flow factors for a Model 225 and 226 are the same as Model 220.
*2. Flow factor for Model 228S is the same as 228C.
3. PV Series is sized for SCH 80 PVC pipe.
All other series are sized for SCH 40 black iron pipe.
