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).

The main purpose of the earth rail: According to the fixed point of the equipment to design, spliced ​​into a cast beam platform, mainly for large equipment assembly, testing, welding and inspection. The use of rail T-slot rails, ground beams, trench iron, the basic advantages of slotted iron: so do not make a large platform, which saves material costs, but also can take up a small space! Can be described as cost-effective use of the rail: According to the fixed point of the equipment to design, spliced ​​into a cast-beam platform, mainly for the assembly of large equipment, testing, welding and testing. The advantages of the rail: so do not have to make a large platform, which saves material costs, but also take up a small space, it is cost-effective. Ground rail material: high-strength cast iron HT200-300, face hardness HB170-240, after two manual processing (artificial annealing 600 degrees -700 degrees and natural aging 2-3 years) to make the product accuracy and durability Good performance. Ground rail specifications: Specific specifications can be produced according to the drawings or the two sides agreed to the production and processing. Botou Mayor River Casting Co., Ltd. Main products for HT200 - HT300 large cast iron plate, cast iron platform, riveting welding platform, the test combination of tipping platform, grinding platform, motor test bench, round platform, boring table boring machine, boring and milling machine Workbench, vertical table, gantry milling machine table, resin sand bed castings, columns, die plate and other large castings.
