chemicals, raw sewage, reclaimed water, cooling water, river water, plant effluent,
etc. Because the instrument and transducers are non-contacting and have no
moving parts, the flow meter can not be affected by system pressure, fouling or
wear. standard transducers are rated to 110
℃
. Higher temperatures can be
accommodated. For further information, please consult the manufacturer for
assistance.
1.6 Data lntegrity and Built.in Time.Keeper
All user-inputted configuration values are retained in the built-in non-volatile flash
memory that can store them for over 100 years,even if power is lost or turned off.
Password protection is provided to avoid inadvertent configuration changes or
totalizer resets.
A time-keeper is integrated in the flow meter for the index of date totalizing and
works as the time base of flow accumulation. It keeps operating as long as the
battery's terminal voltage is over 1.5V. In case of battery failure, the time-keeper
will not keep running and it will lose proper time values.
The user must re-enter proper time values in case the battery becomes totally
exhausted. An improper time value affects no other functions but the date totalizer.
1.7 Product ldentification
Each set of the SUP-2100H series flow meter has a unique product identification or
ESN written into the software that can only be modified with a special tool by the
manufacturer. In case of any hardware failure, please provide this number which is
located on menu window number M61 when contacting the manufacture.
