Pulse Count: The pulse count is stored as an unsigned 32bit
integer. This allows for 2^32 pulses (4.2billion) to be counted
beforerollover.OnModbussystemsthatdonotallowyoutoread
32 bit values, you can calculate the pulse count as follows:
count = (MSW * 65535) + LSW
Instantaneous Pulse Rate:The pulse rate values for instan-
taneous, min and max rates are calculated based on the time
betweenarrivingpulses.Forexample,ifInstPulse1=30,and
