Chemline SG Series Gauge Isolators allow inexpensive pressure gauges, or any other pressure instrument to be used in corrosive services. The upper chamber (gauge side) is filled with a stable fluid such as glycol or glycerine. A diaphragm separates it from the lower chamber which receives the media under pressure.
The 1/2” gauge connection allows use
of the popular 4” and 4-1/2” diameter gauges. Pressure switches or transmitters may also be installed. Customers can easily fill isolators and install their own gauges.
