[clug] [For Sale] Anyone else want an elster reed switch probe?

[Neil Pickford]

Hi Michael

Have checked my meter and it is a recent RMC DN25 Reliance Endurance 
Multijet Turbine Meter.  It does have a location in the face for a reed 
switch, but I'm not sure if the Elster V100 one would be compatible.

I think yours is a Elster Model 20 mm V100 Water Meter:
<http://www.measurement.gov.au/Publications/CertificateOfApproval/OtherInstruments/Water_utility_Meters/Documents/14-3-120071011131054.pdf>

The RMC meter design has a rectangular indent in the perspect face plate 
over the 10 litre dial.  I suspect the 10 litre dial pointer is a magnet 
as it claims 1 pulse per 10 litres.

<http://www.relianceworldwide.com.au/files/spec_sheets/endurance20-25.pdf>
<http://www.relianceworldwide.com.au/files/WaterMeterGuide.pdf> gives a 
good view of the faceplate and rectangular indent.

Now I have looked at it I think I might be able to pot my own reed 
switch to fit in the indent.

Alex asked what to connect it to.

I intend using the Dual Counter 1 Wire board that uses a DS2423 
counter/memory chip.

This will count the pulses and present them on my 1Wire measurement bus.

This in turn is monitored by OWFS (a FUSE virtual file system) on a 
Linux server.  This allows scripts to directly interrogate the hardware 
counter under control from CRON.  Data is presented thru RRDTOOL
