The Rosemount 306 In-Line Manifold is engineered for in-line transmitters. This manifold comes with a male or female threaded NPT process connection and assembles directly to pressure transmitters and gauges for simple in-process calibration. Featuring block-and-bleed and 2-valve configuration for instrument isolation and drain/vent capabilities, this manifold comes factory-assembled to transmitters and gauges, leak-tested and calibrated.
