NOSHOK 1000 Series Differential Pressure Gauge - Manual

Gauge Inspection:
Please read the pr
gauge body to insure that this gauge is the same one speci-
materials of construction, working pressure, di erential pres-
sure, etc. Inspect for any shipping damage and, if discov-
ered, report it immediately.
Product Design Features:
The NOSHOK 1000 Series is a magnetically coupled dif-
ferential pressure gauge. The internal piston/magnet travels
linearly in a very close tolerance bore and a follower magnet,
attached to the pointer, tracks this movement. The pointer,
in turn, indicates the di erential pressure on the dial. By
design, there is a small leakage of media, within the sensor
body, across the piston/magnet from side to side. It can be
seen when the high side is receiving pressure, but the low
side is open to atmosphere. In this condition, there will be no
di erential pressure shown on the gauge. Both sides must
be connected to read the di erential pressure. NOTE: The
1000 Series is not suitable for level indication applications,
or for use with diaphragm seals.
Gauge Mounting:
The 1000 Series gauge is supplied, standard, for panel
mounting. When installing the 2.5” dial gauge into the panel,
remove the four (4) bezel screws, mount the gauge from
back to front through the panel, then reinstall the four (4)
bezel screws through the panel and into the bezel, securing
the gauge to the panel. When installing the 4.5” dial gauge,
install the four (4) threaded studs into the back of the dial
case, mount the gauge from front to back through the panel
and secure the gauge to the back of the panel by tightening
the locking nuts to the threaded studs. Optional pipe mount
kits or wall mount kits are available. (Note: 2 1/2”
Gauge Connections:
Supplied, standard, with (2) x ¼” FNPT back connections
and are clearly indicated with Hi (+) and Lo (-). Optional con-
nection sizes and/or end connections are available.
Troubleshooting:
If the gauge is not indicating di erential pressure, check to
insure that both the high (+) and low (-) connections have
been properly installed. Check to insure that there is pres-
sure to the high (+) side of the gauge and that there is dif-
ferential pressure across the device being monitored by the
NOSHOK 1000 Series. If the gauge is being used together with
a three-valve manifold, check to insure that the high (+) and
low (-) valves are in the open position and the equalizer valve
is in the closed position.
