USAGE: This series of water meter is used to measure the total volume of tape water running through the tape, which is applied to one-way current, but not to hot water and liquid with causticity. TECHNICAL CHARACTERISTICS: This series of water meter's impeller and arithmometer are droved by the magnetism. It is easy to read the amount because it is showed by both digital impeller and index. The panel of the water mater can keep clear-cut for quite a long time and is antifreezing and Iongevous.
As adopting the structure of CMOS chips with small resistance, conse quentlythe precision of computation and delicacy can be high and the beginning flux low. By this way, the problem of missing magnetism and descendant magnetic Force of driving alnico can be solved. Valve adopts globular copper one to reduce the consumption during working. As adopting double reed pipes to bring about the flood, so the sampling of it is with a high reliability. As adopting electric engine with Iow loss of function which can anti resistance and cooperating with imported multi-functional CMOS chips, humanistic soft design and dynamic encrypted arithmetic, therefor, "one household has one card and one code or multi-meters" can be come true. By this way, the security of settlement between the two sides and easy cooperation can be guaranteed. Standard and Main ParametersTechnical standard: The standards of CJ/T133-2001 and GB/T778.1-1996Water maters with the allowably maximal error which accords with the standard of GB/T778.1BConditions of using: The allowably maximal temperature (MAT)40The allowably maximal pressure(MAT)1MPaWorking Voltage: DC3V± 0.6VStatic current: 10uAWorking current: 50mAPrecision permitted: 0.1%Endurable capability: Panel10000 timesValve controled by electrcity: 1000 timesLoss of pressure: 0.1MPA
Subjec Function and demand of technology
Function of displa Display of function Pay money, shut up the valve, misread the cars, low voltage, check up the leak and shut up the valve
Display of number 9999.9 (stere unit)
Function of control Shortage of capacity of batteries When the capacity of batteries is lower than the set value, the water meter will give an alarm and hint to change batteries.
@ Theftproof and snipproof When sampling single is cut, the water meter will give an alarm, shut up the valve and show the sign of attactk. The consumers can not repair. For it must be repaired by manager.
Function of antimagnetism When the additional magnetism closes the meter, the water meter give an alarm and shut up the valve automatcally; While the strong magnetism leaves, one inserts card will open the valve.
Restrict on inputwater One can setup" restrictive volume of water purchased" to prevent the consumers from stocking up the volume of water.
Impulse sampling' s function of dampproof When sampling circuitry and string are damped, the single can still regularly output and collect to make sure data not lose and loss not add.
Valve' s unregular measurement When valve happens to malfunction, regular measure and over-zero measurement will not be affected.
Function of using One card but many meters New meters insert card for the first time. Please write the card number and meter number into new meter to make sure one household can use 8 meters at the same time.
Function of purch asing water Water meter will quickly show the remaining volume of water consumers can use as soon as one inserts the card.
Enquiry card Water meter will quickly show the remaining volume of water consumers can use as soon as one inserts the card.
Enquiry card When water meter turns unregulatly, manager can judge the system regular or not by " enquiry card".
Function of renewing When consumers lose the card, they can renew it.
Function of storing data The data stored in water meter can be kept for over 10 years in the situation of loss of electricity
