TDS-100H Handhold Ultrasonic Flowmeter Ver.8.08 - 5 -
§1.5 Typical Applications
The TDS-100 flow meter can be virtually applied to a wide range of measurements. The
measured pipe ranges 20-6000 mm [0.5 - 200 inch]. 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 110
º
C. Higher temperatures can be accommodated. For further
information, please consult the manufacturer for assistance.
§1.6 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.
§1.7 Product Identification
Each set of the TDS-100 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
