Highly durable construction made of compact and light metal
Flow indicator with alarm contact

FA-3000 Series
FLOW MONITOR■ OUTLINE
FA-3000, flow indicator with alarm contact is the standard model
among a series of FLOW MONITORS which have been widely appreciated by customers.
In addition to the indicator, FA-3000 outputs an alarm contact signal atpreset value. The body constructed of metal frame offers high durability against the stress caused from the mounted piping.

■ FEATURES❏ COMPACT AND LIGHTWEIGHT
FA-3000 is suitable for assembling onto the packaged equipment
and devices thanks to its compact and lightweight design.
❏ DURABLE CONSTRUCTION
Rugged and armored construction endures stress from the piping.
❏ WATERPROOF CONSTRUCION
FA-3000 can also be used under splashes of water.
❏ QUICK DELIVERY AND COMPETITIVE PRICE■ RECOMMENDED APPLICATIONS❏ Monitoring of sealing liquid supply and its stoppage❏ Monitoring of cooling water supply and its stoppage❏ Liquid cultivating medium supply■ STANDARD SPECIFICATION
