Single-Head Bulk Plant Air Eliminator with Optical Sensor
The Single-Head Bulk Plant Air
Eliminator with Optical Sensor performs
the same functions as the Dual-Head
Bulk Plant Air Eliminator. Both air
eliminators use a high mount air
eliminator to siphon air without stopping
the flow. But instead of a low-mount
mechanical air eliminator, the Single-
Head Bulk Plant Air Eliminator with
Optical Sensor uses an optical sensor to
identify large air slugs. When the optical
sensor identifies a large air slug, it
instantly signals an electronic preset or
register (Toptech MultiLoad presets or
Liquid Controls LectroCount registers).
The electronic device closes a
downstream control valve–which stops
the product flow–and the air slug is
quickly vented.
The optical sensor provides several advantages over its mechanical counterpart. The response
time of the optical sensor is much faster than pneumatic-based mechanical air eliminators.
The optical sensor has no moving parts or piping requirements, which can simplify installation
and maintenance.
