6 Reasons why you can choose our flow meters?

1), Over 15 years' experience on the R&D of gas, steam and fluid measurement;




2), Professional sales & tech team offered service in application analyzing, model selection, problem precaution, and troubleshooting;




3), Sonic nozzle calibration system ensures that every flow meter matches the accuracy promised;




4), 70% compressed air system in China choose this product;


5), Ensure that every product delivered has been produced under the toughest quality standard and well calibrated;




6), Have been widely used in Germany, Norway, UK, France, USA.

Generally, two disadvantages we need to consider when we choose a Vortex Flow Meter, they are:

At lower rates, pulses are not generated. Hence flow meter can’t read the low value or sometimes zero;
The vibration of a meter can cause an error in accuracy.

To solve this problem, we continue to test and improve, finally, our vortex flowmeter can measure the flow velocity down to 2m/s and have better anti-vibration capacity than famous brands. Related contrast test with other two famous brands has been done in the factory, if you are interested, we will share with you.

No meter is perfect, but ours are as close as it gets. It will surprise you in a good way when you use it. Please reach us at sales@mega-meter.com for more information. Thank you.
