PMC Engineering
Seal Gauge and SAN Seal Gauge

PMC Seal Gauges accurately measure pressure in industries where viscous materials are processed. The PMC design permits the diaphragm to be installed flush with the inside wall of pipes 3" or larger. This feature avoids the pocketing problems usually encountered with conventional seal gauge systems. The easy-to-read, all-stainless steel gauge is equipped for external damping to promote longevity. Gauges can be removed and exchanged or re-installed without loss of seal oil. Each gauge is equipped with a proven PMC transmitter and can be bottom or back connected for ease of visibility.
