 The table with cash as data storage and transmission medium; selection of multi-jet wet Hebei credit card meter base table, the control valve and the base tables integrated, compact structure, reliability; control valve ball valve structure without pressure loss after torque amplification driven by micro DC motor, reliable work; high-capacity lithium battery life of up to 6 years; fully enclosed design, waterproof, moisture-proof, anti-magnetic, anti-attack. Hebei credit card meter works what is it? Actually quite simple, because Hebei card meter housing is fixed, its internal volume is fixed, while the water is flowing, which promote a rotation of the impeller, whenever one rotation of the impeller, there is a constant volume of water to flow 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. Principle we have clear, then to look at the specific Hebei credit card meter, which is what it, in order to prevent users lid seals allowed to open. Case the ceramic alloy Hebei swipe meter and pipe member 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 modification technology and refining solvent raw material melting and melt purification, gravity casting technology Casting metal molding sand core molding, and strengthened by heat treatment, chemical penetration 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. 
 ? Features: 
 ? ◆ good stability, a full-scale, zero long-term stability of up to 0.2% FS / year. Compensation temperature range of 0 ~ 70 ℃ temperature drift lower than 0.2% FS, the entire operating temperature range of less than 0.5% FS. 
 ? ◆ reverse protection, current limiting protection circuit, positive and negative reversed installation will not damage the transmitter, abnormal transmitter will automatically limit the flow in less than 35MA. 
 ? ◆ solid-state structure, no moving parts, high reliability, long life 
 ? ◆ from the air pressure to the water, the oil can be a high-precision measurement, from the measured medium quality size.
