Operation

The FX series flow switch is the most reliable flow switch available. The thermal dispersion principle of operation features no moving parts and provides an extremely reliable and repeatable switch for the most demanding industrial applications.
The sensor head employs two temperature sensors with a constant very low power heating source physically attached to one of the temperature sensors. The second temperature sensor is isolated from the heating source and provides compensation for changing process temperatures. As flow changes so does the temperature differential. This allows the device to be used as a flow/no flow sensor and to be used to switch at any velocity shown in the flow switch range chart.
Extremely low flow rates can be detected with range ability up to 300:1. These devices are ideal for use in virtually all liquids, gases, and slurries. The no moving parts principle of operation assures reliable and repeatable operation in extremely viscous products.
The electronics are available with single or dual switch points. The instrument can be easily field programmed to detect flow, level or temperature. Relay outputs are standard and are offered with several different configurations and contact ratings. Remote mounting of the electronics is available.



FX SERIES

The FX series flow switch offers the ultimate in reliable and repeatable operation. The no moving parts principle of operation allows these instruments to be used in virtually all liquids, gases and slurries. This line of thermal dispersion flow switches can withstand temperatures to 900F and pressures to 10,000 PSIG. Type 316L stainless steel sensors are standard with options for exotic alloys for corrosion resistance. Many different process connections are available, including threaded, flanged, and retractable probes. Typically this series is used in 1/2” and larger line sizes with our IX
series used in smaller lines.
IX SERIES

The IX series flow switch is an in-line device designed to easily adapt to line sizes from 1/8" tubing to 3/4" pipes. The thermal dispersion principle of operation offers no moving parts exposed to the process and provides an extremely reliable and repeatable flow switch for the most demanding industrial applications. These switches are used to detect the increase or decrease of flow in virtually all liquids, gases, and slurries. Applications include monitoring flow to analyzers, gas chromatographs, and chemical feeder pumps. Flow rates down to .01cc/second can easily be detected.

SX SERIES

The SX series sanitary flow switch has been designed to meet the most critical flow detection applications in the food, pharmaceutical, biotechnology, and water treatment industries. Quick disconnect tri-clamps are standard with special finishes for 3A applications and polished/electropolished for biotechnology and pharmaceutical use. The thermal dispersion principle of operation features no moving parts exposed to the process. The instrument can be used to detect the increase or decrease of flow in virtually all
liquids, gases, and slurries.

FM SERIES

The FM series is designed to provide an extremely reliable flow switch at a very cost effective price. This series replaces the standard explosion proof enclosure utilized in our FX series with a general purpose enclosure. The thermal dispersion principle of operation provides no moving parts exposed to the process and is capable of detecting the increase or decrease in flow of virtually all products. The field adjustable set point can be used to detect flow/no flow or the set point can be configured to alarm at a certain flow rate. A relay output is standard providing a SPDT contact with a 3
amp rating.
