Introduction to granite

Granite is a igneous rock formed by the formation of magma below the surface. The main components are feldspar and quartz. The source of granite is the Latin granum, meaning grain or granules. Because granite is a plutonic rock, it often forms well-developed, visible-grained mineral particles, hence the name. Granite is not easy to weather, beautiful in color, and its appearance can be kept for more than 100 years. Due to its high hardness and wear resistance, it is used as the first choice for high-end architectural decoration projects, hall floors, and open-air carving.

ISO Standard Mass Flow Meter

Zhejiang Sealand Technology Co., Ltd. is a trustworthy manufacturer of Mass Flow Meter Coriolis, Flow Meter Coriolis, Mass Flowmeter Coriolis, Mass Meter Coriolis, Meter Coriolis, Flowmeter Coriolis, ISO/ IEC 17025 standard.

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).

Besides, 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.
