Description

Features:

Adjustable flow monitor
Monitors both gases and liquids
Materials: Brass or 316SS
Confirms: Normal flow conditions
Senses: High flow or low flow conditions
Output: Switch contact

Applications:

Process media
Fire control systems
Cooling systems
Heat pumps
Hydraulic lifts
Water treatment chemicals

Operations:

When flow is increased, the magnetic piston is forced against a bias spring. As the magnet comes near the adjustable reed switch it actuates, indicating proper flow. When flow decreases the spring forces the piston in the opposite direction deactuating the reed switch and indicating a reduce or now flow condition.

Actuation points for air at 68°F and 14.7 psia with increasing flow
Deactuation (decreasing flow) averages 40% less than actuation (increasing flow)
Repeatability ±2%
Unit will pass greater flows
