§1.3 Product Identification
Each set of the RH40 series flow meter has a unique product identification number, or ESN. This number
is written into the software and can only be modified by the manufacturer with a special tool. In the case
of any hardware failure, please provide this number when contacting the manufacturer. It is displayed in
Menu Window M55. The window can be accessed by pressing the following series of keys:
M 5 (System) 5 (Version/SN#)
See section §2.4 for more information on display windows.
§1.4 Data Integrity and Built-in Time-Keeper
All user-entered configuration values are stored in the built-in, non-volatile flash memory that can retain
the data for over one hundred years. The memory integrity is retained even when the power is
disconnected or turned off. Password protection is provided to avoid inadvertent configuration changes or
totalizer resets.
A time-keeper is integrated in the flow meter. It works as the time base for flow totalizing. The time-
keeper remains operational as long as the battery’s terminal voltage is over 1.5V. In the case of battery
failure, the time keeper will not keep running, and the time data will be lost. The user must re-enter
proper time values after the battery is restored. Improper time values will affect the totalizer as well as
many other functions. Re-entering the time value is a crucial step after battery failure because the
totalizer is a factor in accurate flow rate measurement.
