TDS-100H Handhold Ultrasonic Flowmeter Ver.8.08 - 1 -
1. Introduction
§1.1 Preface
Welcome to the TDS-100 (Version 8.xx) series ultrasonic flow meter that has been manufactured
with patent technologies and is equipped with more functions and advanced performance than our
previous versions.
The Version 8.xx series ultrasonic flow meter has been upgraded based on the Version 7.xx series
ultrasonic flow meter, which is still the main product line of the company. The new Version 8.xx
retains most of the excellent features and functions of the previous versions: the pulse measurement
technology, the ultrasonic igniting and the small signal receiving circuits etc. The main
improvements are made on the battery supply circuit and on the transmitting circuits. All other
circuits are simply integrated into this new version without major modifications, due to the fact that
we have already applied the most advanced measurement technologies and attained a more reliable
model of ultrasonic flow meter.
The TDS-100 Series flow meter incorporates the latest ICs manufactured from the famous
semiconductor manufacturers like Philips, Maxim, TI, Winbond, and Xilinx. The hardware features
the ease of operation, high accuracy and outstanding reliability, while the software provides a very
user friendly interface and much more functions. It employs a patent balanced lower voltage
multi-pulse igniting circuit which increases the anti-interference ability magnificently so that the
flow meter will work properly even in demanding industrial environments such as those with power
frequency transverter working nearby.
Other outstanding features:
----the signal receiving circuits feature self-adapting performance so as to ensure that the user can
easily operate the instrument without any adjustment.
----the built-in rechargeable Ni-H battery can work continuously for more than 12 hours without
recharge.
The advanced circuit design, the integration of the latest semiconductors, the user-friendly software
interface both in English and Chinese languages and small-sized PCB board, all these features
combine to make the TDS-100 series ultrasonic flow meter the best and the biggest seller on the
Chinese market. Moreover, it is gaining more and more recognition on the international flow meter
market
