The Modular Mounting System for instrument impulse line installations has been developed in conjunction with Shell International (SIPM) and has particular applications in the petrochemical and refining industries. Based on a standard mounting plate, it allows components to be either preassembled in the workshop or assembled at a later stage, providing maximum flexibility without compromising quality and safety. The Modular Mounting System has a full range of manifolds for differential pressure, pressure and gauge applications, and accessories including GRP enclosures, heating blocks, seal pots, purge blocks and test connection boxes.

ACCU-Mount Systems

Anderson Greenwood’s ACCU-Mount system is designed for the installation of instruments on fiscal metering applications. The system provides close coupling to the orifice tap and full porting to reduce any possible measurement inaccuracy through induced square root error. The system also has a range of other components to ensure the complete installation has full porting and the flexibility for single or multiple mounting of instruments.

Large Bore IntelliMount™ System
Remote, Double block and bleed

The Large Bore IntelliMount direct mount manifold is the next generation of the ACCU-Mount ® System for natural gas, liquid or steam measurement applications. Designed for close-coupling DP or multi-instruments (D/P, pressure, electronic flowmeter, etc.) to senior and junior orifice changers and/or orifice-flange unions. The Large Bore IntelliMount is available in renewable metal or soft seat configurations and features either Grafoil or Teflon stem packings.

The Large Bore IntelliMount’s superior design reduces the number of leakpoints and overall installation weight in relation to the former ACCU-Mount modular manifold system. Furthermore, the Large Bore IntelliMount is factory assembled and tested, decreasing required costly field-installation time.

The Large Bore IntelliMount used with coplanar transmitters features unique patented integral differential pressure/pressure adapter plates. This feature eliminates the otherwise required coplanar adapter flange, removing a potential leakpoint and unnecessary weight.

Materials: Monel Alloy 400, Duplex S31803, Hastelloy C276

Seats: 316 SS, Delrin, Teflon, Peek

Connections: ½-inch FNPT x Female Vent Ports

Orifice Sizes: 3/8” [10mm] bore

Pressure (max): 6,000 psi

Temperature (max): 1000°F [538°C
