The FS-105E model operates in any mounting position. It is equipped with a calibrated piston which is displaced by flow to magnetically actuate a sealed hermetic reed switch. When flow decreases a positive spring returns the piston to its prior position and de-actuates the reed switch. The reed switch assembly is movable to allow for customer setting of flow rate within the limits of the switch selected. The adjustment does not affect the flow path, therefore pressure drop is not influenced when changing set-points. Versions available are for Liquid flow only. Robust components allow a pressure of 250 bar, ideally suited for high pressure cleaning and lubrication systems.
FS-10798 Series – Externally Adjustable for Water, Oils and Gases
These externally adjustable switches are ideal for protecting machine tools from coolant flow failure, for protecting bearings from loss of lubricant or to assure proper air flow. They offer an infinite number of flow settings at pressures up to 1000 PSIG, with low pressure drop and precise repeatability.The adjusting vane is easily field adjustable using an ordinary flat bladed screwdriver. The adjustment is set-screw-locked for tamper-free operation after field calibration.
The FS-107E model operates in any mounting position. It is equipped with a calibrated piston in a calibrated orifice for viscosity compensation over 1 to 600cSt. The piston is displaced by flow to magnetically actuate a sealed hermetic reed switch. When flow decreases a postive spring returns the piston to its prior position and de-actuates the reed switch. The reed switch assembly is movable to allow for customer setting of flow rate within the limits of the switch selected. The adjustment does not effect the flow path, therefore pressure drop is not influenced when changing set points. Robust components allow a pressure of 250 bar, ideally suited for high pressure lubricated systems.
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.
The FS-200 Series offers accurate flow detection, with 1% repeatability, over a broad range of flow settings and port sizes. Its durable construction delivers long-life reliability in either water or oil. Generous flow paths keep pressure drop low. These , switches are ideal for detection of improper flow rates in high volume lubrication, cooling or process systems., FS-200 Adjustable Series switches offer the same accuracy and are as rugged as those with fixed settings, but provide one additional feature: external adjustability. With these versatile switches your choice of flow settings is diverse within a given range. An , ordinary, flat-blade screwdriver is all that’s required for the actuation adjustment.
The FS-200E flow switch offers accurate flow detection with 1% repeatability and European G1″ port size. The durable construction delivers lng life repeatability in either water or oil. The design of large flow paths keep pressure drop low, thus are ideal for detection of flow in high volume lubrication, cooling or process applications.

FS-380P Series – Industrial Strength Inline Plastic Flow Switch
This rugged inline flow switch offers the same superior performance to non-clogging as its metal cousin (FS-380). The fixed set point and simple design make it a dependable switch. The FS-380P is an ideal choice for coolant applications requiring reliable flow detection in HVAC, semiconductor, welding, medical and other industries. 1/4 ̋ quick disconnect units have a host of snap-on mating adapters to fit most piping requirements
These two series of precision-calibrated switches provides reliable and consistent performance; repeatability is within 1%. FS-925 and FS-926 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 processing equipment, monitoring high pressure lubrication systems, and ensuring proper air flow in water/waste systems., , Both the FS-925 and FS-926 use a spring-loaded piston to detect positive flow with great precision. They act upon direct fluid flow and will not show “false-positive” flow indication as can happen with sensors using indirect sensing methods such as pressure , measurement. The FS-926 incorporates an additional lap-fitted piston for very low flows;
Standard FS-550 switches sense liquid flow in either direction to monitor flow/no-flow conditions. They are supplied in two paddle lengths. The paddle is trimmed during installation to permit switch actuation at the desired flow rate. As flow increases in a pipe, the paddle of the switch pivots to move out of the liquid path, producing less than 3 PSIG of pressure drop regardless of pipe size.

The Gems FS-926E Series is a precision low-flow piston-type flow switch designed for very low liquid and gas flow detection. It incorporates a double-piston design, enabling detection of flow rates as low as 50 cc/min, making it ideal for leak detection, chemical dosing, gas sampling, and semiconductor cooling applications.
RotorFlow® Switches build an extra level of reliability and , protection into your equipment. By principle of operation, the rotor cannot be deceived into indicating a positive flow situation when no flow actually exists. Once set to a desired actuation point, RotorFlow will switch to a “no-flow” condition should the rotor stop for any reason.
The Trantech TTPFS30 Mechanical Paddle flow switch designed to detect the presence or absence of liquid flow in pipelines. Operating on a simple mechanical paddle principle, the switch is actuated by the movement of liquid against the paddle, providing a dependable SPDT microswitch output for pump protection, equipment interlocking, alarm indication, and process control. The adjustable paddle can be trimmed to suit a wide range of pipe sizes, making the TTPFS30 suitable for water, cooling systems, hydraulic circuits, lubrication systems, and general industrial process applications.
