Proservo NMS5
Remarks
• Set access code to 51.
Default value is 2 points
and selectable up to 16
points.
• Whatever the number of
measuring point is
selected, the measuring
interval & point between
each point are automati-
cally calculated within the
liquid level.
Remarks
• Set access code to 51.
NMS software has a func-
tion to scan & record the
liquid level every 5 min-
utes.
• NMS5 only starts the
actual measurement when
the liquid level is within
the entered value
compared to the recorded
level data 5 minutes ago.
This function ensures the
safe operating condition to
avoid filling or draining
liquid from the tank.
Remarks
• Set access code to 51. The
displacer raises approxi-
mately 500mm above liq-
uid surface after confirm-
ing the stability of liquid
level within "BAL LEVEL"
function.
• The displacer weight is
calibrated at 8 different
positions in air and the
interval between those
positions are adjustable
within this function to
allow excess liquid to drip
off the displacer to achieve
higher accuracy.
