1. Introduction
§1.1 Preface
Welcome to use Our Ultrasonic flow meter that has been manufactured with patent technologies
and is equipped with more functions and advanced performance than our previous versions.
Our U ltrasonic flow meter has been upgraded based on the Old 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.
Our Ultrasonic Flow Meter is using latest ICs 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 ultrasonic flow meter. Moreover, it is gaining more and more recognition on
the international flow meter market
§1.2 Features
* 0.5% of linearity * 0.2% of repeatability
* Bilingual interface in Chinese and English * 4 flow totalizers
* Patent balanced lower-voltage multi-pulse * built-in date totalizers
ultrasonic igniting * built-in data-logger
* Work properly near transverters * 0.5 second totalizing period
* 100 Pico-second resolution of time measurement

§1.3 Principle of Measurement
Our Ultrasonic flow meter is designed to measure the fluid velocity of liquid within a closed
conduit. The transducers are a non-contacting, clamp-on type, which will provide benefits of non-
fouling operation and easy installation.
The transit time flow meter utilizes two transducers that function as both ultrasonic transmitters and
receivers. The transducers are clamped on the outside of a closed pipe at a specific distance from
each other. The transducers can be mounted in V-method where the sound transverses the pipe
twice, or W-method where the sound transverses the pipe four times, or in Z-method where the
transducers are mounted on opposite sides of the pipe and the sound crosses the pipe once. This
selection of the mounting method depends on pipe and liquid characteristics. The flow meter
operates by alternately transmitting and receiving a frequency modulated burst of sound energy
between the two transducers and measuring the transit time that it takes for sound to travel between
the two transducers. The difference in the transit time measured is directly and exactly related to
the velocity of the liquid in the pipe, as shown in Figure1.

§1.5 Typical Applications
Our 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 ºC. 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 Meinte 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
