Pulse Water meters

looking for some sort of pulse unit to measure water.

found these water meters but the one that does 1 pulse/0.5L only is 25mm im looking for a 40mm

the 40mm i have found does 1 pulse/10L

does anyone know of any decent 1 pulse per 0.5-5L units? they dont have to be actual water meters just that thats all i seem to be able to find.
looking for 40mm size as to not restrict pipework and allow a decent flow through

Try doing a google search for manuelectronics.com.au

They have various 40mm models (MES, MES-MR) that have 7.2 pulses per litre on there datasheets.

I don't know the prices though.
