What are the types of counters?
Electromechanical counters, electronic counters, and programmable counters. Electromechanical counters use mechanical gears and levers to count events, while electronic counters use digital circuitry to count and display the number of events.
What is the difference between a counter and a totaliser?
Counters measure the number of times an event has occurred, while totalisers measure the total amount of a specific process variable, such as the total amount of fluid flowing through a pipeline.
