The PG200 single scale process gauges and PG250 dual scale altitude gauges provide high accuracy and premium materials for demanding applications such as water tank levels and system pressures. The process gauges rugged phenolic case are completely sealed and may be surface-mounted for panel applications. Both the PG200 process gauges and PG250 altitude gauges are filled with glycerin, which absorbs shock, reduces vibration effects and lubricates the movement to assure a long trouble free service life.*
Single Scale Process Gauges
The PG200 Single Scale Process Gauge has a large, easy read single scale dial that shows psi. These gauges are typically used in evaluating water systems for pressure problems and obtaining system modeling data.
Dual Scale Altitude Gauges
Commonly called an "altitude gauge", the PG250's large dual scale shows both feet of head (WC (Water Column)) and PSI. Since there is a direct correlation between water pressure and water column (the highest level of the water above the measuring point), altitude gauges are commonly used to determine level readings on water tanks and towers.
*NOTE: Due to the large case volume of the process gauges some leakage of fill material is normal as a result of temperature and pressure variations. Glycerin is a low-reactive, non-hazardous liquid.
