Omega Engineering FSW-50 General Description, Specifications, Flow Range water calibrated @ 70˚F

Notes	General Description
	The OMEGA® FSW-50 Series Flow Switches feature a 15A SPDT switch
	and an internal screw adjustment which provides continuous switch point
	adjustment while in operation in-line. Multiple drag disks are supplied
	with each unit to provide incremental switch point adjustment. Their non-
	magnetic design makes them ideal for applications where rust is a problem.
	The FSW-50 comes standard in a plastic/316SS construction. The FSW-50
	Series is also available in a special PPS* Hastelloy C and Viton construction.
	The FSW-50 Series are for use in highly particle-contaminated liquids
	such as sewage, machine cutting oils and medium slurries. The standard
	models can be used in mildly corrosive liquids such as low to medium
	concentration acids and bases; sea water, sewage oils; rusty coolant water,
	etc. The special PPS* Hastelloy C and Viton construction models are for
	use in concentrated corrosive liquids such as sulfuric, nitric, hydrochloric
	and acetic acids; ferric chloride; aqueous ammonia; benzene; magnesium
	chloride, etc.
	Particle contamination resistance is provided by a flexible filter boot
	which prevents crystallization, caking, heavy dirt concentration, slurries,
	scum, etc., from affecting the operation of the flow detector. The FSW-50
	Series Switches respond to flow only, independent of line pressure,
	temperature and environment.
	During emergency conditions these switches signal catastrophic system
	failures such as line breakage; pump failure; incorrect valve opening or
	closing; pipe, valve or filter clogging, etc.

Specifications

FLOW RANGE (water calibrated @ 70˚F)

The maximum flow range flexibility is provided by three adjustment options:

1. Continuous adjustment while operating via a calibrated FORCE/BALANCE spring.

2. Step incremental adjustment via drag disk size change.

3. Continuous adjustment via moment arm change.
