After the 26th, there will be small to moderate rain (snow) in the south of the Nyingchi area and the southern part of the Shannan area, and heavy rain (snow) in some places; light rain (snow) on the cloudy days in the southern part of the Shigatse area and the Changdu area; cloudy areas in other areas, and snow in some places ( rain). In the early period of the middle and early period of the middle and the northern part of the Shigatse region, there were about 8 strong winds.
Precipitation in the eastern region is frequent, and geological disasters such as mudslides and landslides are prone to occur. The relevant departments are advised to take precautions; the main agricultural areas in the Yarlung Zangbo River Valley still have little or no precipitation, so strengthen field management.
Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Natural Gas Mass Flow Meter, Natural Gas Mass Flowmeter, Natural Gas Coriolis Meter, Natural Gas Coriolis Mass Flow Meter, ATEX, IECEx & CE approved.
First, Sealand meter is certified by Zhejiang Institute of Metrology. To get such certificate, Sealand has to send all models to Zhejiang Institute of Metrology and all models are tested in their calibration lab. The lab is an ISO/IEC 17025:2005 standard lab approved by CNAS (China National Accreditation Service for Conformity Assessment). CNAS is a member of ILAC (International Laboratory Accreditation Cooperation).
Second, Sealand has its own calibration lab, equipped with METTLER TOLEDO scales with accuracy 0.014% and the device extended uncertainty is 0.05%. The lab is also approved by Zhejiang Institute of Metrology. This certificate will stay valid only for one year, Zhejiang Institute of Metrology will send their professor to Sealand every year to check and make sure that the lab is qualified still and then issue new certificate. During the production, each meter will be calibrated in this lab for 3 times, each time at 5 different flow rate.
Finally, Sealand also gets ISO, CE, SIL, ATEX & IECEx. Sealand is the only Chinese brand who gets ATEX & IECEx and it is from TUV SUD ( the most authoritative institute for ATEX).
