BULLETIN NO. IM140-02 Mid-West (Supersedes BULLETIN NO. IM140/01) ® Instrument Model 140 "DELTA METER Installation and Operating Instructions INSPECTION Before installation check the nameplate on each instrument against the receiving paperwork and the intended application for correct part number, materials of construction, working pressure, dial range, etc. If equipped with switches, check electrical rating, type of enclosure, etc. Inspect for shipping damage and, if damaged, report it immediately.
Be sure these get plumbed to the proper connections on your system. Improper connection will not damage the instrument, but it will not function properly. Flexible tubing is recommended to minimize effect of any vibration that may exist. 2. INSTRUMENT LOCATION On liquid service, the instrument should be mounted below the process connections to facilitate self-bleeding. On gas service, it should be located above the process connections to promote self-draining.
