 Meriam Digital Indicators
The MERIGAUGE digital pressure gauge from Meriam Instrument successfully
addresses the modern demands of process pressure measurement. Pressure
ranges are available to 6,000 PSIG at standard accuracy of ± 0.25%
of Full Scale and optional accuracy of ± 0.10% of full scale.
The standard gauge is powered by two 9 volt alkaline or lithium batteries.
E xternally powered units are available. The pressure display is
a 4 1/2" digit LCD with 0.6" high numerals. Each gauge includes 12
field selectable engineering units. The selectable units include
PSIG, feet of water, inches of water, inches of the mercury, Bar, millimeters
of mercury, kilopascals and user configurable units. In addition
to numeric pressure indication, visual indication of the pressure is represented
by an adjustable vertical bar graph on the left side of the display.
Other standard features include Min/Max query, Zeroing, selectable Damping,
selectable program Lock-out, adjustable display shutoff and field recalibration
and adjustable display shutoff (for battery powered models). The housing
is 304 stainless steel and NEMA 4 rated. Wetted components are 316 stainless
steel for compatibility with many process fluids. Process connection is
via a 1/4" MNPT 316 stainless steel stem.
