 After the upload procedure is finalized, turn off the application.
 For the next upgrade, just change the firmware in the directory and perform the
above mentioned procedures.
NOTE
After each upload, try to configure the MAC address of
the CommVerter as well as other parameters as required.
MPI-C - DYNAMIC PULSER SAMPLING PERIOD
1. GENERAL
The dynamic sampling period is introduced to better cope with low quality pulsers. The MPI-C is
required to count high frequency pulses ( up to 5K PPS ). With slower and low quality pulsers,
intermittent noise (resulting from pulser relay bouncing) is inside the band width of the 5K MPI-C
pulses range. It is suggested to have an adjustable pulser sampling period that will be closer to the
actual pulse rate.
2. CALCULATION
The actual sampling rate will be calculated base on the Pulser Factor.
Parameters:
F = Factor in Pulse/Liter
FR = Pump Flow Rate in Liter/Min
PPS = Pulse per second
PW = Pulse Width in millisecond
