Parker CCIMS level-flange integrated DP manifold concept

The CCIMS level-flange, a highly integrated manifold concept from Parker Hannifin, is designed to offer users a simpler means of installing level measurement instrumentation to process tanks and vessels.

Two single-piece manifolds integrate all of the valves and features required for connecting the upper and lower pressure sensing points to a differential pressure transmitter. The approach eliminates a large amount of weight, size and potential leak paths compared with conventional installations using discrete valves and tubing connections.

One manifold provides a single-piece solution for the lower or ‘wet leg’ pressure connection at the bottom of a tank. This has a flange at one side for connection to the tank, double block-and-bleed valves in a monoflange style, a mounting point for a differential process transmitter and tube connections for the balance line connection to the second sensing point. The second manifold provides an integrated solution for the upper or ‘dry leg’ pressure sensing point, with a flange connection, block-and-bleed valves and balance line connections.

The design provides a short, straight and even flow connection increasing instrument accuracy and the close-coupled design ensures that the differential pressure instrument is mounted directly adjacent to the process vessel.

A complete assembly with instrument extends around 26.3 cm from the tank and the CCIMS level-flange is expected to reduce the installation time and cost of differential pressure transmitter level measurement systems by up to 85%.
