Traditional (non spring) vs. EZ-View®(spring)

Page 5: Hedland EZ View Variable Area Flow Meters

Comparison • Traditional

– Lower Pressure Rating – Low Pressure Drop– Lower Flows– Vertical Mounting– Limited Viscosity Range– Sensitive to Shock

• Hedland– Higher Pressure Rating– Higher Pressure Drop– Flows > 0.5 GPM– Install in Any Position

• no special piping or flow straighteners needed

– Viscosity Range to 400 sus– Insensitive to Shock &

Vibration

EZ-View® in Action• As the fluid or gas enters

the meter, it is directed around the metering cone

• The pressure differential created by the flow around the cone causes the piston to move against the spring

Flow-Alert® Flow Switches• Reed

– N.O., N.C., SPDT (Form C) versions available– Fully encapsulated– Changes state when internal magnet is in proximity -

returns to original condition when magnet moves away

• Latching– 10-30 VDC or 115 VAC versions– N.O. contact, closes when internal magnet reaches

set point– Remains closed until magnet moves back across set

point, or if power is cycled– Indicator light when contact is closed
