PRESSURE REGULATORS WITH FILTER CONDITION DETECTORS

摘要

Example pressure regulators with filter condition detectors are described herein. In one example described here, a regulator includes a body having an inlet and an outlet and a flow control member interposed between the inlet and the outlet to regulate a fluid pressure at the outlet. The example regulator also includes a filter disposed between the inlet and the flow control member and a detector having a first measurement point upstream from the filter and a second measurement point downstream from the filter and upstream from the flow control member.
