Compound Pressure Gauge with Dual Pointers
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. Dual dial is often used in pay formations where the pressures in these processes range from high to low, depending on how the formation is being treated. 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. Because this gauge has two pointers: a 360 degree sweep dial makes one full rotation while the 4:1 Vernier needle makes 4 full rotations, even the smallest pressure changes can be seen. The dampener assembly located on the top of the gauge, dampens vibrations and reduces pointer bounce so that pointers move in steady, even actions.
The compound dual pointer pressure gauge comes equipped with two pointers and a dial that displays readings in two different PSI increments. For example, the black inner dial indicates PSI, and the yellow pointer indicates 1, 2, 3 or 4 thousand PSI. One complete sweep of the yellow pointer indicates 4000 PSI. The outer white dial indicates PSI as well; however, the max capacity is divisable by a factor of 4, and will be in 8,000, 12,000, or 16,000 PSI, depending on the application's max capacity.
The system consists of a 6-inch Pressure Gauge, a Gauge Protector, and a Hydraulic Hose.
All Crown Dual Pointer Mud Pressure Gauges are built to meet or exceed API specifcations.
