SG Series Gauge Isolators

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 ½" gauge connection allows use of the popular 4" and 4-½" diameter gauges. Pressure switches or transmitters may also be installed. Customers can easily fill isolators and install their own gauges.
