Product Description
DEFINITION:
Set of moving device that fitted into a closed conduit driven directly by water flow. Its turbine rotor rotates about the axis which is perpendicular to water flow.
WORKING PRINCIPLES:
Water flow drives vane rotate. Rotating times which is proportional to water flow speed are gathered, hence total volume passed through water meter is recorded.
CHARACTERS:
Types: Wet, dry, vertical, liquid sealed.
Wide measuring range, high accuracy.
Stable measuring capacity
Long working life
Low pressure loss
All technical figures are conformed with GB/T778. 1~3-1996 which is equivalent to ISO4064 Standard Class B.
WORKING CONDITION:
Water temperature≤45ºC(Hot water meter≤90ºC)
Water pressure≤1Mpa
MAXIMUM PERMISSIBLE ERROR:
From the minimum flow-rate (qmin) inclusive to the lower zone of the transitionalflow-rate (qt) exclusive: ±5%.
From the transitional flow-rate (qt) inclusive to the higher zone of the maximum flow-rate (qmax) exclusive: ±2%(hot water meter±3%. )

27/9/2011, The Water Meter Production Base of Zhejiang Younio ( Zhejiang Younio Water Supply Equipment Co., Ltd) standed alone and set up a wholly-owned subsidiary - Wenling Younio. (Wenling Younio Water Meter Co., Ltd), whose registered capital is RMB30 million.
08/12/2011, Zhejiang Younio signed an official agreement with Jiangxi Sanchuan which state that Jiangxi Sanchuan will be controlling shareholder and bring Wenling Younio going public.
01/01/2012, Wenling Younio start to run And we are planning to be the biggest water meter export base in China within next three years.
Wenling Younio. Covers an area of more than 5000 square meters with a staff of more than 150, owning design and R&D center, accessories production center, whole machine production center, inspection and testing center. We are now capable of producing about 2 million pieces water meters annual. We have successively passed the certificate of ISO9001: 2008 Quality System Certification, the certificate of ISO14001: 2004 Environmental Management System Certification and the certificate of GB/T 28001: 2001 Occupational health and safety management system certification. With a wide variety and a complete range of ecifications. Our products are exported to many countries in the world such as Eastern Europe, South America, Africa and the Middle East, etc. Exports accounted for more than 85%.
Welcome old & new customers home & abroad for business & kind instructions.
