Pulsars for woltman water meters for Telemetry
We want to use existing woltman type water meters for installing a Telemetry/ SCADA for a major water supply scheme in Tamilnadu. For linking these water meters to the SCADA signals have to be tapped from the meter read out. I understand that there are different options are available for the pulsars - Reed pulsar, Opto pulsar and Namur pulsar. Can I get some more details on these options and also where they can be sourced. I am Government Water Supply Engineer at Tamilnadu, India.
