In most municipal water applications in which a pulse-based water meter is used, the pulse count is generally preferred to totalize without reset. However, in certain automated plant/process situations, it is desirable to halt the flow of metered liquid after a certain quantity and then to re-zero the metered total. These applications are often described as “batching” operations.
When the EtherMeter is used in pulse-counting mode, the pulse count may now be reset to zero remotely and automatically. In Modbus-based control systems, writing a ‘1’ to Modbus Coil 9 resets CNT1 to zero, and writing a ‘1’ to Modbus Coil 10 resets CNT2 to zero. In Allen-Bradley-based control systems, writing a ‘1’ to B10:0/8 resets CNT1 to zero, and writing a ‘1’ to B10:0/9 resets CNT2 to zero.
