4 Instruction Manual
Transducer cable: RS232 interface cable
1.6 Typical Applications
The ultrasonic flow meter can be virtually applied to a wide range of measurements. A
variety of liquid applications can be accommodated: ultra-pure liquids, potable water,
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 90 ºC. Higher temperatures need high temperature type transducers.
1.7 Data Integrity 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.
1.8 Product Identification-ESN
Each set of the ultrasonic 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.
