LIQUID FILLED GAUGES
Models 1550/1553 2-1/2" (63mm) and
4" (100mm) All Stainless Steel Gauges
DESCRIPTION
SPECIFICATIONS
The Model 1550 and 1553 are 2-1/2" (63mm) and 4"
(100mm) affordable liquid filled gauges that have all 316
stainless steel wetted parts. They are designed to endure
the harsh environments of chemical and petrochemical
processing plants. Liquid filling extends the life of a dry
gauge in these environments by protecting the movement from vibration and dampening any shocks the
gauge may experience. The liquid filling also improves
readability by minimizing the vibration that is transferred
to the pointer.
SIZES: 2-1/2" (63mm) or 4" (100mm)
t Glycerin is the standard fill fluid, with silicone and
mineral oil available upon request. These gauges are
also available dry, and can be filled at a local distributor
or at your facility.
