LFE Electromagnetic Digital Flow Switch. 0.5 to 200 l/min. Local 3 colour display

The LFE flow monitor uses the magnetic inductive or sometimes called the EMF principle to infer the velocity of a conductive liquid moving in a pipe. This is then indicated as a rate and total on the LFE’s built-in display along with a scaled pulse or alarm output and either a second switch or an analogue 1-5V or 4-20 mA signal. This versatility in outputs and the fact the meter has no moving parts make them ideal for monitoring cooling water circuits to things like moulding and casting machines. As long as the media is conductive it will work even if polluted. Not suitable for demineralised (demin) water or high percentage water/glycol mixes.
