Kelco C25 25mm Magnetically Operated Piston Inline Flow Switch

The C25 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 90ºC. The C25 flow switches can be supplied with reed switch contacts for relay or PLC control or with a built in 40Amp solid state switch for the direct control of single phase motors up to 3kW 4HP.

For safety shower applications we recommend using our C25-B model with the dry contact reed switch.

FEATURES

• Australian made
• Brass and Polypropylene construction
• 1 Inch BSP or NPT inlet & outlet thread
• All position mounting
• Diesel and oil models available
• Choice of reed switch or solid state switch
• Maximum flow rate of 100L/min
• Static or Dynamic pressure rating up to 100bars 1450psi
• Very low head loss
• Weatherproof

APPLICATION

• The C25 flow switches can be used in many clean liquids, including fresh water, sea water, and diesel fuel.

CONSTRUCTION

• The C25 flow switch consists of a sealed electrical switching module that saddles a one-piece metal body.
• The self contained electrical modules fitted to the flow switches is easily removed without disturbing pipework, and can be reversed or rotated independently of the switch body.
• Within the metal body of the flow switch a free fitting magnetically suspended piston actuates the switch as soon as flow starts.

SWITCH POINT DATA

• Switching point and sensitivity to flow depends on liquid velocity, viscosity and piston clearance.
• To give users as wide a choice as possible, three pistons and a non-magnetic piston retainer are supplied with the C25 flow switches.
• The three pistons allow the choice of a high, low or intermediate range of switching thresholds.

INSTALLATION

The C25 flow switches can be positioned in any orientation in pipework. In vertical piping, flow can be either upward or downward through the switch with very little difference in flow sensitivity. The C25 flow switch is suitable for use with hot or cold liquids up to 90°C. Systems can be steam sterilized at 100°C for short periods without damaging the switch.

ELECTRICAL APPLICATION:

All C25 flow switches are single pole single throw normally open switches that switch on in response to flow. The model C25-B is suitable for PLC use, data logging, telemetry systems, relay logic circuits, or any light duty control application in either AC or DC circuits. It is rated at 0 to 240V AC at 40Watts maximum switched power. The model C25-R is suitable for AC use only, and can directly control any AC motor load up to 3kW 4HP. The C25-R will not operate in DC circuits or in circuits that draw less than 10mA.

ENVIRONMENT:

• Max. Liquid Temp.:  90°C, 100°C for short periods
• Min. Liquid Temp.:  -20°C
• Max. Liquid Pressure:  100 Bars (1450 PSI)
• Ingress Protection Rating:  IP56
