Other description:
This product use the best material and advanced manufacturing technique.Every finished product have to inspect.The regular type of product is in stock and have the most efficient delivery time. Max. production capacity:2 thousands sets.The normal delivery time after ordered: 7 workdays.This product have exported to Finland,Korea,etc. Clients like Laser Gas Oy,etc.
Our company established in 1957 and have more than 50 years experience of manufacturing thermal instrument.We rank 5 in our profession industry.Products have exported to France, United States,United Kingdom,Spain,Finland, Germany, India, Korea, Turkey for more than 20 years.Our clients like Airliquide Group in France, Laser Gas Oy in Finland,Kaltech engineering & refrigeration Pte,Ltd, etc. Export amount exceeded to 100 thousands sets.
The quality standard is : JB/T6844-1993, and according to ISO9001:2008 to control the quality.Each product has to inspect contain leak tightness test, pressure test, etc. We ask our supplier provide test report of raw material, each electrical element has to detect, so every finished product has factory test report and data record.We introduced special technique and equipment from KROHNE in Germany, 228 sets fabrication and gauging equipment to calibrate the flowmeter,  and also NCM,milling machine,grinding machine from Japan to ensure the accuracy of the spare part. Self-production proportion of spare part up to 90%
Capability of product research and development: Every series product team is consist of a senior engineer and several technical engineers. When we receive the technical request different to exist product, we can customize  the product by technical drawing or customize according to the sample.The sampling period is 20 workdays. 
1.Superior economic performance.Due to the instrument is made by metallic material, so it can work safety in extremely diafusting condition.
2.Simple structure, reliable performance.Needn't upstream and downstream straight pipeline section. Purely mechanical structure, needn't  power supply, less component, maintain easily.
3.Unique viscosity amendation.The unique viscosity amendation make the flowmeters's indication get closer to actual working condition.
4.Widely used.Precise measurement and control, can choose 1~2 alarm switch.
