1. Introduction
1.1 Preface
Welcome to handheld ultrasonic flow meter that has been manufactured with patent
technologies and is equipped with more functions and advanced performance than our
previous versions.
The ultrasonic flow meter has been upgraded based on the previous ultrasonic flow meter
which is still the main product line of the company. The new Version 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.
Handheld flow meter incorporates the latest ICs manufactured from the famous
semiconductor manufacturers like Philips, Maxim, TI, Win bond, and Xilinx. The hardware
features the ease of operation, high accuracy and outstanding reliability, while the software
provides a very friendly user 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 transverses 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-MH battery can work continuously for more than 10 hours
without recharging.
The advanced circuit design, the integration of the latest semiconductors, the user-friendly
software interface and small-sized PCB board, all these features combine to make the
ultrasonic flow meter the best and the biggest seller on market and gaining more and more
recognition on the international market.
