 Diaoyu Islands are the main islands of Diaoyu Islands are China's inherent territory, located in the East China Sea, about 356 kilometers away from Wenzhou, about 385 kilometers, Keelung City, about 190 km, an area of ??4.3838 square kilometers surrounding sea area of ??about 170,000 square kilometers. 1972 its administrative jurisdiction "with the Ryukyu" to the Ryukyu Islands in Japan, history does not belong to Japan. Japan over the Diaoyu Islands dispute arising therefrom. Since the 1970s, the Chinese civil society organizations have repeatedly expand "Diaoyu Islands to proclaim sovereignty movement.

 The table with cash as data storage and transfer medium; selection of multi-jet wet Hebei meter base table, the control valve and the base tables are integrated, compact structure, high reliability; pressure loss ball valve structure control valve, amplified by a miniature DC motor through a torque-driven, reliable work; high-capacity lithium battery life of up to 6 years; fully enclosed design, waterproof, moisture-proof, anti-magnetic, anti-attack. Then the the Hebei water meter works, what is it? Actually very simple, because the the Hebei meter housing is fixed, its internal volume is fixed, while the water is flowing, it promotes an impeller is rotated, whenever the impeller rotation, there is a constant volume of water flowing through. Therefore, as long as the rotation of the impeller laps cumulative down, multiplied by this constant volume, you can get the total amount of water flowing through. The principle we have been clear, and then to specifically look at the the Hebei water meter which is what it is not allowed in order to prevent users lid seals open. The ceramic alloy Hebei meter case and fittings adopted by the aluminum, magnesium, zinc, as well as additives like aluminum alloy as the raw material, the use of the rapid melting and titanium, strontium and rare-earth polyhydric metamorphic processing technology and melting the raw material and melt refining solvent purification gravity casting technology Casting metal molding sand core molding, and heat treatment to strengthen, chemical permeation and electrochemical oxidation process, ensure the quality of the case.

 ? Sensitive components using diffusion or ion implantation process to form a resistor connected in a Wheatstone bridge, with the formation of a pressure-sensitive diaphragm micro-machining technology in electric bridge. When the pressure on the diaphragm, the resistance value changes and generates a linear output signal proportional to an applied pressure. Wheatstone bridge plus a DC power supply, it will produce a DC voltage signal output. After secondary conversion circuit, two-wire 4 ~ 20MA output.
