Standpipe Pressure Gauges & Unitized Pressure Gauges

Crown Oilfield Instrumentation offers Standpipe Pressure Gauges & Unitized Pressure Gauges (UMG) that come standard with a 2″ male NPT, 2” 1502 hammer union type, flanged type and threaded. These mud pump pressure gauges (also known as Standpipe Manifold Gauges) are easily view-able at distances and provide the same reliability as our standard 6” gauges. Just like reading a large clock at a distance, Crown UMGs offer provide an easy-to-view, full-faced, liquid-filled dial, unlike a Type F or D that only has a half-moon shaped dial. With built in dampener assembly and blow-out plug safety feature, these gauges stand up to over-pressure situations, kicks, and rig vibrations.  This style of gauge is ideal for mud pumps, stand pipes, choke manifolds and pump trucks and can be used in cementing, fracturing, and acidizing gravel-packing trucks, blowout preventers, and mud pump pressure gauge applications.

All Crown Unitized Mud Pressure Gauges are built to meet or exceed API specifcations.
