A. GENERAL INFORMATION
The Hauck Orifice Metering System is a family of assemblies of thr eaded or welded design used for
measuring the flow of either com bustion air or any industrial gas. These meters m ay be used in the
main gas and air lines or in the gas and air lines of individual burners. The former configuration
allows the monitoring of total flow while the latter method allows precise setting of each burner .
B. RECEIVING AND INSPECTION
Upon receipt, check each item on the bill of lading/and or invoice to determine that all equipment has
been received. A careful examination of all part s should be m ade t o ascer t ain if there has been any
damage in shipment.
bearings, if applicable
excessive moisture.
C. INSTALLATION
1. Install the orifice meter in any position in the appropriate line. Most orifice m eters are available
in either of two configurat ions: one designed specifically for a welded connection, the other for
a threaded female connection. The location chosen for installation should permit easy access
to both pressure cocks and allow sufficient space t o r em ove the or ifice plate, if requir ed.
When used in the gas and air lines of individual burners, mount the orifice meter between a
flow control valve and the burner.
downstream of the orifice.
2. Insert and loosely tighten the three ( 3 ) connect ing bolts not required to hold the or ifice plate
in position.
3. Insert the orifice plat e and secur e it in place by insertion of the fourth connecting bolt.
