IC CARD COLD (HOT) WATER METER-THE CPU SERIES Endo

The product technology characteristic: 1. One-body structure, it is the smallest size compared to similar IC cardwater meter (patent number ZL00 2 05850.2). a) Effectively prevent the counting-inaccuracy caused by thevibration. b) Remarkably reduce the energy consumption of the interior parts, thus enhance the battery life c) Enormously enhance the pressure-resistance intensity, the workshop pressure-resistance examination may reach above 3Mpa. 2.Unique structural design of the machine core(patent number ZL01 2 24631) a) Can realize the high measuring accuracy, the sensitivity, lowinitial current capacity. b) Solved the problem of the magnetism loss resulting from the overload current capacity and the problem of transmission magnet steel magnetic force drop. c) imported double pipe messaging, the reliability of sampling is high. 3. Unique valve design (patent number ZL00 2 05851) a) The fore-leading hole of the fore-leading valve is located in the active valve core, each time when valve moves, the leading hole iscleaned, which guarantees the reliable work of the valve. b) The valve engine uses the magnetism transmission controlling circuit to isolate the valve aqueous system, solve the problem of moving-seal difficulty. c) Using the self-design special-purpose low power loss anti-disturbance electrical machine, the work is steady, the energy consume is low. d) Using the fore-leading electrically controlled valve designed through the combined technology of the magnetic force and the water power, resulting the low power loss of the water meter, alsoresulting the reliable and stable opening and closure of the valve under the low pressure condition. e) The number of times that the valve opens and shuts can achieve 10,000 times, is 10 times of the national standard; 4. The degree of encryption is high, cannot break the code, and is suitable for wide range transformation of water meters. 5. May realize the incremental water price. 6. Large volume of water reservation, the electric meter can share the same card as the gas meter, thus it realizes only one card for one household, and can connect to the banking system.The product standard and the main parameters: 1. The product technical standard carries out CJ/T133-2001 and the GB/T778.1 standard. 2. The largest allowed error of the base meter conforms to therequirement of the GB/T778.1B-level meter. 3.
