OPERATION
Display. There are two lines to the display, one for flow rate
and one for accumulated total. The units used are indicated
on the display. Units are pre-ordered and factory set, and
can not be changed in the field.
If the display indicates letters and digits, the meter has
power and should be functioning normally. If there is no
display (the display is blank) the meter is not powered.
Calibration. The WMX101 is factory calibrated and should
not require any form of field calibration.
Empty Pipe Detection. All magmeters require a method
for determining that the pipe is empty, since in many cases
an empty pipe may otherwise cause a false reading. This
meter uses a software-based empty pipe detection method.
It should immediately go to a zero reading if one or more
electrodes is exposed.
Caution: There are no connections inside
the display. Breaking the seal wire will
VOID WARRANTY.
