PULSE METER SUPPORT 

 
The EtherMeter provides meter-reading support for pulse-based meters.  As a consequence, pulse 
meter signal(s) may be connected to either (or both) of the EtherMeter’s meter input channels. 
 
Pulse processing technology allows the EtherMeter to collect meter totalization and flow rate data 
from  non-encoder-based  meters.    Common  examples  include  petroleum  &  chemical  meters, 
commercial & industrial natural gas meters, volume correctors, and many others. 
 

 

 
 
When the EtherMeter handles pulse-based meters, the totalization and flow-rate data is stored and 
transmitted  from  the  same  Modbus-  and  Rockwell-compatible  memory  registers  that  it  uses  for 
encoder-based  meters.    Therefore,  regardless  of  which  type  of  meter(s)  is  connected  to  the 
EtherMeter  (encoder  versus  pulse),  collection  of  totalization  and  flow  data  by  the  connected 
SCADA system is identical. 
 

Supported Pulse Input Types: 

 

•

 

Mechanical Dry Contact 

•

 

Solid-State Dry Contact 

•

 

Open-Collector Input
