FIELD ADUSTABLE ALARM SETTING UNRESTRICTED MOUNTING Only an allen wrench is required to change theflow alarm setting. Allows the designer to install the monitor in anyorientation – horizontal, vertical or inverted. WEATHER-TIGHT CONSTRUCTION ECONOMICAL PROTECTION Rugged cast aluminum NEMA type 4 enclosureallows installation in outdoor applications and in environments where liquid tight seals are required. This monitor rapidly pays for itself as it soundsthe alarm on incorrect pneumatic, lubrication or cooling volumes, protecting expensive equip- ment and reducing downtime. SIMPLE ONOFF LOGIC UALITY ASSURANCE Positive alarm points using 0 A., dry-contact,SPDT switches, reduce the complexity found in standard rotameter OFF/ON/OFF circuits. Can be an integral part of a quality control system, yielding consistent system operation. PRE-WIRED WITH CABLE DISCONNECT The standard Hirschmann interconnection provides easy installation and maintenance of the FLOW ALARM and the system it is a part of.

ENGINEERING SPECIFICATION THE IN-LINE FLOW RATE MONITOR/ALARM SHALL: ? Have field adustable, dry-contact, alarm settings. ? Use the variable annular orifice technique with compression spring recoil. ? Not require inlet or outlet straight plumbing, or require vertical pipe mounting. ? Have a measuring accuracy of ±2.5% of full scale in the center third of the measuring range, and ±4% in upper and lower thirds. ? Have a maximum working pressure rating of500 or 6000 PSIG for liquids. ? Have a maximum working pressure rating of 600 or 000 PSIG for gasses. ? Have a stainless steel sharp-edged orifice. ? Have a weather-tight NEMA type 4 external construction. ? Be Lake Monitors No. M _ _ – _ _ _ – _ _ for single alarm applications, or N _ _ – _ _ _– _ _ for dual alarm applications.
