Ernst Flow Industries™ valves are simple, rugged instruments engineered and constructed
throughout to give you accurate liquid level reading for the life of the vessel. With a
complete range of models for any application, from pure water to highly corrosive chemical.
Like any instrument, Ernst Flow Industries™ gauge valves must be installed, operated and
maintained with reasonable care and due regard for the application and environment.
INSPECTION AND DELIVERY
Upon receiving valves, check all components carefully for damage incurred in shipping.
Confirm that valve model number and pressure temperature ratings (on nameplate) meet
application specifications. Also confirm that the material is compatible with both process
fluid and surrounding atmosphere for your application.
CAUTION: Ernst Flow Industries™ gauge valves are not to be used for gauging lethal
substances as defined by ASME Section VIII.
BEFORE YOU INSTALL THE GAUGE
VALVES
• To avoid imposing piping strains on the
valves, connect and mount the valves
so that they do not support the piping.
• Support brackets should be
considered, if level gauge is over four
feet in length or over 100 pounds in
weight, especially when exposed to
vibration. Support brackets will prevent
overloading the valves.
• When installing liquid level gauges,
always provide shut off valves between
gauge and vessel. Ernst Flow
Industries™ automatic ball check
valves are recommended to help
provide protection against physical
injury and loss of product if glass
breakage should occur.
