Introducing the FM Series Heavy Duty Flow Switches

Suitable for the most arduous heavy-duty applications in industry and mining, the new FM series paddle
flow switches are built tough.  The entire switch body is CNC machined from solid aircraft grade
aluminium and 316 stainless steel.  The switch itself is superbly sensitive and it only requires
4 grams of force against its paddle to actuate its magnetically coupled switch.Two switches are
available in the FM range, a general purpose 5 to 500VAC SPDT or a 0 to 30VDC SPDT switch with gold
contacts for low wetting current applications.

Introducing the LM Series Heavy Duty Level Switches

A solid range of industrial and mining grade level switches suitable for tank level control in fully exposed
locations. The entire switch body of the LM level switch is CNC machined from solid aircraft grade aluminium
and 316 stainless steel. The switch itself is magnetically coupled to its float arm meaning there are no seals or
diaphragms to leak or fail within the switch.   Two switches are available in the LM range, a general purpose
5 to 500VAC SPDT or a 0 to 30VDC SPDT switch with gold contacts for low wetting current applications.

P25 Series

Features

  • Directly control pump motors
  • Ideal for PLC and relay logic
  • Manual override (P25-S Model)
  • Suits pipe sizes 15mm to 25mm (1/2″ to 1″) Dia.
  • No metal parts in contact with liquids
  • 100 litres per minute flow rating
  • Versatile all position mounting
  • 18 Bar (260psi) pressure rating
  • IP67 Weatherproof housing
  • Detects very low flows

Description

The P25 inline flow switch is a rugged versatile all position mounting flow actuated switch that can detect the flow of liquids in 15mm (1/2″) to 25mm (1″) diameter pipes. The P25 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, 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 such as groundwater, seawater and in acidic and alkali solutions. 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 Pipe-work.

Applications

  • Safety shower alarms
  • loss of prime protection for pumps
  • Flow monitoring for large dosing systems
  • Control of tank filling systems
  • Low yield bore pump protection

    Description

    The MF20 micro flow switch is a super sensitive version of our popular P20 in line flow switch. The MF20 is a very simple and reliable mechanical flow switch that can detect extremely low flows; the switch can detect either continuous or pulsed flows. Typical applications include monitoring chemical metering pumps to ensure they are delivering flow, in water treatment, cooling towers and in a multitude of industrial processes. The MF20 flow switch gives a simple on or off response to liquid flow. There are no metal parts in contact with liquids within the switch, so the MF20 is ideal for use in aggressive media such as acids and alkali’s and many chemical solutions. The standard switch is supplied complete with tube flare fittings, for 3 popular tube sizes, and a set of pipe spigots and unions, for direct fitting into 15NB PVC or ABS pipe work. In addition, a number of electrical options are available. These include electrical modules with single and multiple reed switches, relays with various coil voltages, and solid-state switches.
