Liquid Level and Flow Switches

Electro-Optic Level Switch Guide

ELS Series Level Switch Sensors are low cost, compact, optical water
level sensors with built-in switching electronics. With no moving parts,
these small units are ideal for a variety of point level sensing applications
— especially where dependability and economy are a must. Level switch
sensors are suitable for high, low or intermediate level detection in
practically any tank, large or small. Installation is simple and quick
through the tank top, bottom or side. Solid state-switching ensures
dependability over long service life. These water level sensors offer
±1mm repeatability and broad liquid compatibility. They are not
recommended for use in any liquid that crystallizes or leaves a solid
residue.

Flow Switches

GEMS’ line of flow switch devices and pressure switch instruments feature
a broad range of configurations for use in liquids or gases. At preset rates,
ranging from 50 cc/m to 100 GPM, a GEMS flow switch will initiate alarm
actuation or automatic shutdown of a system. These flow switch units
feature high quality, corrosion-resistant materials for use in the toughest
environments. Material choices, ranging from stainless steel to Ryton®,
offer vast chemical compatibility. Versions include switches with fixed or
adjustable actuation settings, models for viscosity compensation or high
pressures, in-line models and designs to satisfy any mounting or space
requirement.

Flow Switches piston-type
FS-3 Series, Compact, Low Flow Units

These ultra compact switches have been specifically designed for reliable
operation in clean post-filtered water. They are made primarily of Noryl ® ,
with all other wetted materials also FDA or NSF compliant. FS-3 switches
are instrument-quality, yet affordably priced for pure water equipment...
from U.V. Lamp switching to Filter Life
Monitoring. Also well suited to
some chemical applications and a
variety of cooling applications: lasers
and heat exchangers where clean
recirculated water is used. 
 

FS-4 Series, NEW DESIGN !
Low Cost, Molded Plastic Construction

New molded body design features uniform wall thickness for more
reliable performance!
The FS-4 Series makes flow protection economical for a broad range of
industrial applications such as welders, lubrication systems, medical
sterilizers and laundry chemicals dispensing.
 

FS-150 Series, Straight Flow Path
with Low Pressure Drop

These slim, inline switches reduce pressure drop to a minimum. They
incorporate a unique, dual-diameter, internal bore and piston configuration
to minimize flow constriction. Liquids are able to smoothly pass around
the piston and flow through the switch with little pressure loss to the
down stream line.
 

FS-380 Series, Compact Flow Switch
for High Inline Pressures

These rugged inline flow switches require 100 micron filtration and are
less susceptible to clogging than other high-pressure inline flow switches.
The one-piece magnetic PPS composite piston makes the FS-380 ideal
for high-pressure applications such as industrial cleaning equipment.
The FS-380 is also an excellent choice
for semicon cooling applications
where simple design and reliable
operation are required.
 

FS-925 Series, General Purpose

This series of precision-calibrated switches provides reliable and
consistent performance; repeatability is within 1%. FS-925 units are
factory preset for actuation at specified flow rates.  These switches
provide accurate detection of excessive or insufficient flow rates in such
applications as: protecting against loss of fluid flow in hydraulic systems,
assuring proper coolant flow in semiconductor processin equipment,
monitoring high pressure lubrication systems, and ensuring proper air
flow in water/waste systems.
