KELCO Diesel/Oil Inline Flow Switch - DN25 (1”) Scr BSP C25 Series

The C25 inline flow switches are versatile magnetically actuated normally off flow switches that switch on in response to a selectable flow.

They are ideal for a multitude of clean liquid applications including pressure boosting and for the direct control of pumps or fans.

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

FEATURES:

• One piece brass body.
• All position mounting.
• Diesel and oil models available.
• Choice of two electrical modules.
• Choice of three switching ranges.
• Very low dead loss.
• Fully serviceable.
• 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.

HAZARDOUS APPLICATION:

The C25-B flow switch with an in built dry contact reed switch can be used in hazardous areas. The switches are classed as simple devices as they do not contain components capable of storing or producing an electric charge. As simple devices the switches can be used in hazardous applications provided they are isolated by an intrinsically safe barrier, a Zener barrier. The model C25-R flow switch is not suited to such applications, and will only operate in AC circuits.

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
