If there are any questions about the shipment, please call OMEGA Customer Service Department at (203) 359-1660. Upon receipt of shipment, inspect the container and equipment for any signs of damage Take particular note of any evidence of rough handling in transit. Immediately report any apparent damage to the lipping agent. NOTE The carrier will not honor any claims unless all shipping material is saved for their examination. After examining and removing contents, save packing material and carton in the event reshiprrtent is necessary. PRINCIPLE OF OPERATION (See Parts Diagram) An orifice piston containing a magnetic ring is located inside of the Flowmeter body, and is part of the sliding piston assembly. A spring returns the piston and magnet to the "no flow" position. There is a flow orifice in the center of the piston which is blocked in the "no flow" position by the stationary metering cone. The piston movement presents a gradually increasing flow area. Incoming flow will build up pressure to push the piston to a position on the cone where the pressure drop across the increased area and the spring force are in balance. The variable area feature produces uniform scale increments throughout the adjustment range. A — Electrical Outlet B — Ground C — Flow Meter Cartridge Asm.

Water hammer occurs when a liquid flow is suddenly stopped as with quick closing and solenoid operated valves. Surges occur when flow is suddenly begun, as when a pump is turned on at full power or a valve is quickly opened. Liquid surges are particularly damaging to flowmeters if the pipe is originally empty. To avoid damaging surges, fluid lines should remain full (if possible) and pumps should be brought up to power slowly and valves opened slowly. In addition, to avoid both water hammer and surges, a surge chamber should be installed. -PARTS DIAGRAM 1/4" SPECIFICATIONS ACCURACY: ±5% full scale REPEATABILITY: ±1% full scale SWlTCHrMicro SPDT; 15 amps @ 480 Vac MAX.

TEMPERATURE: 240°F for FL-7600; 180°F for FL-7825 FLOW METER BODY: Aluminum EFFECT OF DENSITY: The meter is affected by fluid density. Most petroleum based fluids have a specific gravity very close to the .84 used for calibration. For heavier fluids, the indicated flow reads high and correspondingly lighter fluids cause the readings to be low. For these cases a properly calibrated scale can be used or a correction factor applied to the standard scales. A correction chart is available for fluids from 1.25 to .65 specific gravity. The correction factor is: Oil Scale — ^.84specific gravity Water Scale — NJl.O specific gravity For petroleum based hydraulic fluids, this correction factor is small enough to be ignored. Meters are calibrated for air with a specific gravity of 1.0. For gasses heavier or lighter than air refer to conversion chart. PRESSURE DROP (LOSS) OIL Approximate pressure drop of oil at normal temperatures. Add 10% to pressure for water. CALIBRATION: Meters are calibrated for oil at .84 specific gravity at 110°F±5°F; water at 1.0 specific gravity at 110°F±5°F; or air at 100 psi and 70°F.
