Meter Reading
The total flow that has passed through your meter is read by starting at the top of the
register with the Five-Digit Totalizer, and then read clockwise around the small dials.
In the example below, the Five-Digit Totalizer reads 13800 (138 x 100), and the dials
read 60 (6 x10), 2 (2 x1), and 0.4 (4 x 0.1) respectively. The total flow is 13862.4.

MAINTENANCE/REPAIR
Preventative maintenance consists of periodic inspections and cleaning procedures.
The procedures should be performed at regular intervals, and any defects discovered
should be corrected before further operation of the meter.
Visually inspect the meter for missing hardware, broken resistor glass, or other signs
of wear or deterioration. Verify proper flow rate and pressure for meter. A loss in
pressure, with the resulting flow rate decrease, may indicate the meter screen is
clogged and requires cleaning.
Clean the strainer yearly, or as required, depending on water condition. Pull out the
strainer or back flush the meter to loosen trapped particulates.
The Series WMT2 is not field serviceable and should be returned if repair is needed.
Field repair should not be attempted and may void warranty.
