Product description:
The variable area flowmeters with metal cone is used for liquids and gases . You can mount it horizontally or vertically. There are models of local indicating, long-distance data transmission, corrosive resistant, with heating device, limit switch, explosion-proof and so on. Transmission has 0~10mA analogue signal output, suitable for electro-unit combination instrument DDZ-II or DDZ-III. It has the function of flow accumulating, digital communication. On-line correcting parameter, various power supply and so on. We can provide flange and magnetic fliter on customer's request. It widely applied to petroleum industry, chemical plant, power atation, food processing, pharmaceutical factory and water processing.
Quality standard:
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.
