Overview

Handheld Ultrasonic Flow meter

QYB-2000H 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 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-MH battery can work continuously for more than 12 hours without recharging. 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 QYB-2000H 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.

Principle of Measurement

The QYB-2000H 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 QYB-2000H 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, show as follows:LCD Battery Industrial Handheld Portable Ultrasonic Flow Transmitter Flowmeter for Liquid Water Oil
Where
     θ is the include angle to the flow direction
     M is the travel times of the ultrasonic beam
     D is the pipe diameter
     Tup is the time for the beam from upstream transducer to the downstream one  
     Tdown is the time for the beam from downstream transducer to the upstream one  
     ΔT=Tup -Tdown
