§1.1 Preface
1. Introduction
The FDT-25 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 NiMH 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 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
