II. MGG/KL-ICRG Electromagnetic heat meter
MGG/KL-ICRG Electromagnetic heat meter is based on radio frequency card(contactless card)as hot water meter for the information carrier of IC card manage- ment, It’s consist of sale of water management system (including management software and reader-writer ), electromagnetic heat meter, contactless card, valve, etc. The instrument used the high precision accuracy and the high reliability electromagnetic flow meter for flow measurement. It also used platinum thermal resistance with high accuracy and high stability for temperature measurement and make the heat meter has very excel- lent performance measurement; meanwhile it has the advanced intelligent lock valve and Implementation of 20 KAILIU INSTRUMENT prepaid measurement concept. Which can be widely used in the occasion of heat measurement for heating and air conditioning in residential , office buildings and enterprises and institutions. It’s feature are low power consumption , high precision , strong anti-jamming , anti theft measurement , good reliability and easy installation, etc.It can achieve remote data acquisition , processing , display , preservation , billing and automatic control , etc. The meter has achieved heating management information and modernized instrument for heat supply management.
The feature of smart IC card management system:
1. Prepaid function: It can achieve management mode of buy heat before use and effectively solve the problem of cost default;
2. The balance of alarm: Valve closing will warn one time when residual heat is less than the alarm value set. In order to avoid delay user is normal heating and arrange the time to buy heat ,user can use IC card open valve after them find valve closed;
3. Hoarding limited functionality: The meter is limit for users to buy heat. Hoarding limited value can be set up by the IC card and instrument will not be read user's purchased heat in card when the sum of allowance and amount of top-up beyond the limit;
4. Card and value refund function: The users can check the card and value refund at any time;
5. Report the loss of card function: User can re-make a card in management terminal if the user lose the card. 6. The original card is invalid after re-made;
7. The data cards function: Management terminal will extract service data of instrument from the IC card. It including cumulative dosage, and the rest of the dosage, dosage of the month, the valve state etc, when the user purchase heat in every time.
8. One card is only for one meter: By setting up users password and check code way to achieve one card only for one meter. It’s meaning one user special card is only for one meter, others are invalid;
9. Preventing magnetic interference function: when meter and the strong magnetic interference affect the normal measurement of the meter, meter valve will close, magnetic interference elimination is available after the user card punching valve;
10. Automatic maintenance function of the valve: Valve switch regularly is effectively avoid the phenomenon of fouling and can’t open valve when rust, in favour of the valve is working for long time.
11. Changed the mode of indoor reading meter, reduced management cost of heating department, the users can decide to premium time and quantity by themselves, increase the autonomy of users;
12. Convenient to perform beyond the heating fee of the plan and the fee of step wise, and others complex heat using management modes, etc.
13. It can effectively solve the problems about measuring the dispute, heat using dispute, corruption charges, heat using with human relationship, the difficult of heat using statistics etc.
