The PULSE sensor has 2 types of inputs : 

  • "Gas" (pull-up activated) , 
  • "Other" (pull-up disabled).  

The "Gas" type is to be selected for Gas meters as well as for equipments that has an "open collector" type pulse output (such as some flow meters for example). 

The "Other" type is to be selected for most water meters (which often require a pulse module, not supplied with the Pulse) and for most electric meters that generate a dry contact type pulse.
