Following the binary output devices capable of detecting a presence or loss of a flow within less than 0.01 seconds, ifm has launched the SBY433 and SBY434 which provide the same fast response, but with a 4 to 20 mA analogue signal.

The setting range of the SBY433 covers 1 to 25 litres/minute, while the SBY434 can be set between 2 and 50 litres/minute, in each case with minimal pressure loss.
