Dual Pointer 4:1 Compound Pointer Pressure Gauge Systems

Crown Oilfield Instrumentation’s Compound Pressure Gauge systems are designed to provide a quick, accurate display of pump pressure. Main applications are for hydrostatic testing, down hole cementing operations and high pressure fracturing.  These gauges can also be used for checking pump pressures on service trucks, down hole acidizing stimulation situations, and fracturing operations. This gauge has two pointers: a 360 degree sweep dial makes one full rotation while the 4:1 Vernier needle makes 4 full rotations, so even the smallest pressure changes can be seen.

The system consists of a 6-inch Pressure Gauge, a Gauge Protector, and a Hydraulic Hose.
