The C25 inline flow switches are versatile magnetically actuated normally off flow switches that switch onin response to a selectable flow. They are ideal for a multitude of clean liquid applications including pressureboosting and for the direct control of pumps or fans. The C25 flow switches can be supplied with reed switchcontacts for relay or PLC control or with a built in 40 Amp solid state switch for the direct control of singlephase motors up to 3kW 4HP

The F21 flow switch is a tough but highly sensitive paddle flow switch suitable for a wide range of flow control applications in both hot and cold liquids. The electrical housing of the switch is a separate assembly and locks onto the wet end of the switch. The Kelco inline flow switch can be easily and safely removed for servicing, without disturbing electrical wiring. This unique feature, and the inclusion of a built-in manual override make the F21 a very versatile flow switch. In addition to the standard micro switch models the F21 is available fitted with reed switches for PLC, relay logic and telemetry applications.

The C15 inline flow switches have a compact design, with a magnetically-actuated piston that switches in response to flow. They are ideal for many types of pressure boosting and control applications in both hot and cold liquids up to 90C.

The F Series flow switches are tough, but highly sensitive paddle flow switch suitable for a wide range of flow control applications in both hot and cold liquids and a variety of chemicals. The electrical housing of the switch is a separate assembly and locks onto the wet end of the switch. It can be easily and safely removed for servicing, without disturbing electrical wiring. This unique feature, and the inclusion of a built in manual override make the F Series a very versatile flow switch.

The paddles for our F Series switches are supplied at a set length. These paddles can be cut down to suit your pipework and flow rate. We recommend using our Paddle Trimming Calculator (linked above) to find the correct paddle length for your application.

The F25 series flow switch has been specifically developed to fill the need for a flow sensor, capable of working reliably in applications in which metal flow switches fail. Typical areas include chemical, process, pharmaceutical, scientific and agricultural uses in which the metal components of traditional flow switches either interfere with or are attacked by, the liquids being handled. Modern thermoplastic pipe systems are used extensively in agriculture, industry, and in commercial and domestic fluid handling. The F25 flow switch has been specifically designed to integrate into plastic piping systems and to enhance the advantages of such systems. Total avoidance of metal components, in the fluid stream, has been achieved. In addition, an advanced frictionless sensitivity adjusting system gives total external control over the switching threshold.

The FM series flow switch is built tough for the most arduous industrial and mining applications. It is a rugged but highly sensitive paddle flow switch suitable for a wide range of flow sensing applications in both hot and cold liquid. The FM series flow switch can be supplied with a glass fibre reinforced Polypropylene paddle or a stainless steel paddle. The paddle can be cut and shaped as required to suit pipework 25mm (1 inch) or larger. A unique feature of the FM flow switch is its built-in manual override. The manual override allows the flow switch to be switched on at any time at the press of a button regardless of lack of flow. Using the manual override allows pumps to be manually started at any time by simply pressing the button. It also makes the testing and commissioning of systems very simple. A magnetic coupling system is built into each FM flow switch and couples the movement of the paddle to the high compliance switch through a solid wall of stainless steel and aluminium. The result is a high-pressure flow switch with no seals diaphragms or bellows or other points of potential failure. The FM flow switch is supplied as standard with a one-piece 316 stainless steel process connection and a fully machined billet aluminium housing. The switch is suitable for use in bore water, seawater and in many chemical solutions. There is also a dedicated Diesel and high-temperature compatible version available with a stainless steel paddle.

Kelco is an Australian Manufacturer of etremely accurate and reliable flow and pressure switches plus pump controllers and level switches. We have been supplying Kelco products for many years and our customers are very pleased with the quality and reliability.

Our facilities consist of a modern toolroom equipped with the latest CNC machinery for die and mold production. In addition, we also operate comprehensive manufacturing processes, including in-house injection molding, assembly, testing, and warehousing for our range of products.

All Kelco Engineering products are designed, manufactured, and tested in-house, to meet the exacting standards of our international customers. Most products meet or are approved to internationally accepted standards.

The FM Series flow switch is built tough for the most arduous industrial and mining applications. It is a rugged but highly sensitive paddle flow switch suitable for a wide range of flow-sensing applications. The FM Series flow switch can be supplied with a glass fibre-reinforced Polypropylene paddle, or a Nickel Copper alloy paddle suitable for use with diesel and high-temperature applications.

The CR22 microflow switch operates on the displaced piston principle. Process liquid passing upwards through the switch lifts a precision piston. Every time the piston is lifted a magnet sealed inside it actuates an external reed switch. The reed switch provides a signal indicating flow. The CR22 can be set up as a normally on or a normally off switch that responds either to flow or to loss of flow.

The P25 inline flow switch is a rugged versatile all-position mounting flow actuated switch. The P25 switches come with the option of 15mm, 20mm, or 25mm pipe connection sizes. It can be used in larger pipe systems provided the maximum flow does not exceed 100 liters per minute. The switch can detect very low flows and yet has a low head loss and a high flow-through rating. It can be used to detect continuous or pulsed flows.

The P25 finds a myriad of applications in industrial, rural, and domestic pumping systems. It is particularly well suited to pressure pumps due to its ability to detect and switch at extremely low flows. In addition, the P25 can be used to protect low-yield bore pumps and in tank-filling applications.

There are no metal parts in contact with liquids. The P25 flow switch is supplied complete with unions and standard PVC pipe sockets for direct solvent gluing into PVC pipework. The union threads on the P25 are standard parallel BSP form and where required can be used to secure the switch directly into threaded pipework.

The UB25 Series inline flow switches are magnetically actuated piston-style sensors that switch in response to very low fluid flows or flows up to 100L/min. These switches are ideal for all types of pressure-boosting pump control and for the control of commercial or domestic hot and cold water systems.

The UB25 flow switch is supplied as standard and fitted with a magnetic piston retainer that allows the switch to be oriented in any required position in the pipework. In the vertical pipe, the workflow can be either upward or downward through the switch. There are no springs in the wetted area of the switch, which with the magnetically isolated piston provides an exceptionally reliable mechanism. For monitoring of industrial safety showers where extreme reliability is paramount, we recommend our UB25-C model.
