The five-valve assembly for differential pressure transmitters
Thread Content
Are the 2 ports at the bottom of the five-valve assembly used for draining waste? If it is used for waste discharge, then are these 2 ports still needed to be connected with pipes? If takeover is needed, would a 1/2NPT-ф12 adapter be required?
OP, the two interfaces below the five-valve assembly serve a dual function of drainage and calibration. From a safety perspective, wastewater cannot be discharged directly; instead, pipes should be extended to a waste drainage ditch/slot for collection. So takeover is required, as well as a 1/2NPT-ф12 adapter.
