Flowmasonic WUF100 Ultrasonic Flow Meter

Flowmasonic is ultrasonic flow meter series WUF100 adopts a state-of-the-art, single-board technology featuring high precision, high reliability, high performance, low price, etc. that make it the ultrasonic flow meter of choice by many customers from all over the world. It’s main features are:
  • The sensors being clamp-on type, there’s no pressure loss. The sensors are easily mounted on the surface of the pipe without interrupting the flow for installation or maintenance.
  • Advanced intelligent display, computation and printing(data logger) to suit user’s diversified requirements. The flow is displayed in all pertinent engineering units. It runs out of regular AC power(110V/220V), built-in batter or DC power.
  • Using the most advanced direct-time-measuring method, the meter offers a signal resolution of 0.2ns. In addition, advanced data processing functions ensure Flowmasonic series WUFof high linearity.
  • Signal outputs including current signal, frequency signal, serial data, switch outputs(1 OCT and 1 relay output). All the outputs displayed on the unit can be transmitted to a PC via RS-232/485 for further processing or storage.

 

The Flowmasonic is 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.

 
Working Principle of Transit-Time Technology
  • For the measurement, two ultrasonic pulses are sent through the medium, one in flow direction, and the other against it. The transducers are alternatively working as emitter and receiver.
  • The transit time of the ultrasonic signal propagating in flow direction is shorter than the transit time of the signal propagating against flow  direction.
  • The transit-time difference Δt is measured and allows the determination of the average flow velocity on the propagation path of the ultrasonic signals.
  • A profile correction is performed to obtain the average flow velocity on the cross-section of the pipe, which is proportional to the volume flow.
The Flowmasonic WUF100 Series transit time clamp on 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 of flow masonic flow meter 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 flowmasonic series WUF100 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.
 
Non-Invasive, Clamp-on Transducers 
Since ultrasounds propagate in solids, the transducers can be mounted onto the pipe. The measurement is therefore non-invasive, and no cutting of pipes is necessary for the installation of the transducers. Because with just 3 sets of transducers, pipes ranging from 15mm to 6000mm can be covered, the ownership cost doesn’t increase as the pipe size increases, which is the decisive cost saving factor as compared to traditional flow meters.

1. WUF 100J

Flowmasonic series WUF 100J 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 WUF100J 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 of flowmasonic WUF 100J 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 pipeand the sound crosses the pipe once. This selection of the mounting method depends on pipe and liquid characteristics.
The WUF100J Hand Held Ultrasonic 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 differencein the transit time measured is directly and exactly related to the velocity of the liquid in the pipe.

The WUF100J hand held ultrasonic flow meter that a battery-powered ultrasonic flow meter with the capability of a full-size flow meter. It is carefully designed for portability and ease of use.
The hand held flow meter is based on clamp-on transit-time flow measurement principle. It measures the flow rate of liquid in a pipe from outside of the pipe by using a pair of ultrasonic transducers. In general, the liquid should be full in the pipe, and should contain very little particles or bubbles.
Examples of applicable
  • Water (hot water, chill water, city water, sea water, etc.);
  • sewage;
  • oil (crude oil, lubricating oil, diesel oil, fuel oil, etc.);
  • chemicals (alcohol, acids, etc.);
  • waste;
  • Beverage and liquid food, solvents and other liquids.

Features :

  • Due  to  the nature  of  clamp-on  technique,  the  transducer  installation is simple  and  no  special skills  or  tools  are  required.
  • There is no pressure drop, no moving parts, no leaks and no contamination.
  • The built-in rechargeable Ni-H battery can work continuously for more than 10 hours without recharge.
  • The WUF100J hand held flow meter has also a built-in data-logger, which allows storage of 2,000 lines of data. The stored information can be downloaded to a PC through its RS232 connection port.
