Dwyer Instruments Capsuhelic 4000-0 Installation And Operating Instructions

CAUTION: Use of a line filter (Dwyer model A-391 or equiv-
alent) is recommended to prevent entry of liquid borne par-
ticles into gage. Dwyer Instruments cannot assume
responsibility for failure of gages due to clogging of internal
passages.
NOTE: DO NOT use with hydrogen gas. Toxic and/or ex-
plosive gas may form due to reaction with rare earth mag-
net.
CAPSUHELIC ® INSTALLATION
1. Select a location free from excessive vibration and where
the ambient temperature will not exceed 200°F. Sensing
lines may be run any necessary distance. For example, 250
foot lines will not affect accuracy but will damp the reading
slightly. Do not restrict lines. If pulsating pressures or vibra-
tion cause excessive pointer oscillation, consult factory for
means of providing additional damping.
2. All standard models are calibrated for use with the
diaphragm and scale in a vertical position. Special factory
calibration is necessary for operation in an inclined or hori-
zontal position. The exceptions are ranges under 5 in. w.c.,
(or metric equivalents) which can only be calibrated for ver-
tical operation.
