SOR 1520 OEM Flow Switch - Manual

Form 454 (11.13) ©SOR Inc. 1/8
1520 Top Mounted
Flow Switch
General Instructions
Registered Quality System to ISO 9001
The SOR ® 1520 Flow Switch must be mounted in a vertical position (horizontal
pipe run). Electric switching is caused by the liquid flow moving the vane and
magnet into the field of a hermetically sealed reed switch capsule. Flow
switching takes place at approximately 1 ft./sec. velocity.
Two separate cavities make up the body — one for the magnetic/vane arm,
one for the switch.
Before Installing the Level Switch
 Inspect the unit for any shipment damage.
 Check for mechanical clearance of the vane. The vane must
move freely without binding throughout its stroke.
 Use an acceptable thread compound when installing unit to
ensure
a leak-free fit and to avoid thread galling.
 When installed, the direction of flow should match the direction
of the arrow on the unit.
Design and
specifications are
subject to change
without notice.
