Ultrasonic gas flow meter is designed on the theory of acoustic transit time. Two transducers send sonic wave to each other, and upstream transit time is longer than downstream transit time, and the difference value is related to flow rate. Then the volume can be calculated out.

Features:
    Stability, High accuracy, 10Ns time resolution ;
    Can detect 0.01m/s low velocity flow;
    Large turndown Ratio , more than 1:30, 0.5% of reading Accuracy;
    Max. Viscosity 30m/s;Highest pressure up to 10MPa;
    Size from DN25mm-DN300mm
    Temp. and pressure signal input, other signal input

•Ultrasonic research center focused to improve UGF stability and   accuracy
    a. Revise programming language, optimize menu, improve communication error and pulse output , improve wiring way and add power protection           
    b. Have AGC function, signal amplifier times shall change according the signal strength to comply with the process pressure and medium changes 

Core technology-Low pressure transducer
      Ultrasonic transducer is one of  the most important core parts of UGF and we have independent intellectual property rights.
      High sensibility, stable signal, anti-oxidation, oil/water corrosion. The company hole the key technology, some parameter reach international standard.

Core tech.-High press. Transducer
     High press. Transducer is another key technology and most important technical parameter. we introduce high transducer from Russia , which can be used both in high pressure and low pressure with the features of stability, sensibility, not losing signal even after long time testing., good response.

Core technology- Signal collection, AGC, linearity correction based on digital processor 
       on testing,DN40 testing velocity up to 33m/s, Error<0.5%,repeatability<0.1%.

Main features"
1.High accuracy 0.5%;Repeatability up to accuracy *1/5.(highest accuracy 0.5% of reading).
2.Temp. and pressure compensation, and measure Standard and engineering flow.
3. Bi-directional measurement, smart body, easily installation.
4. No moving parts, Low maintenance period and long working life.
5. Cheap after-markets service, don't need to add any types of lubricant and couplant
6. At most no pressure drop
7. No ultrasonic radiating , no voice, no vibration, Environment-friendly , ultrasonic signal more than 142Khz to protect external vibration.
8.  No moving parts and don't affect the working
9. to  be main trend of gas measurement
