The ministry of construction address that to let civilians feel relieved on payment of water, meter taking is very serious. However, the work is not successful. The main reasons are:
• great manpower is needed to for taking meter reading,
• a serious security problem happened if the operators go into the house for taking meter.
NingBo LongKang Intelligent Water Meter Company has broken through the traditional concept that the meter should be in one piece and put all different components, like card stand, main circuit board and LCD, on the wall of the users while the others, like valve controller and snap-proof circuit board, are put indoor. The two are connected using signal wires, which are also snap-proof, to ensure safely working. The management department can use a tool card to check the meter reading of some of the users then take back the card to office and carry out analysis.
Exterior implement:
The outdoor insertion card intelligent water meter opened up by NingBo LongKang Intelligent Water Meter Company has compact and coordinate structure. The products are reliable, stable, and they have a long life-span. The specials are:
• Use logical encryption or CPU card, one password for each table, non-decipherable.
• Use stable hardware and software, solve interference and high power problem.
• Use import pith material, which make the battery work for over 5 years.
• Reliable current checking function, can set an automatically closure of valve when low power to cut the water circuit.
• The water meter solves the traditional valve leakage problem.
• When the sum of purchasing amount in card and the usable amount in meter exceeds the maximum amount, the meter will automatically reject the sum to avoid the stock up of water.
• When the usable amount equals alarming amount, the meter will be automatically switched off and alarmed, the user need to insert the user card to continue.
When the usable amount in meter has used up, the meter will be automatically switched off and shown “clear bill”, “usable amount 0” and so on.

Maximum accumulated amount is 9999.9m 3 |
Control |
Usage |
When the usable amount equals alarming amount, the meter will be automatically switched off and alarmed, the user need to insert the user card to continue. |
Low battery |
When the battery current is lower than the preset value, the system will show a switch-off warning. The use need to insert user card to continue. |
Battery enquiry |
The system will automatically screen the circuit to see if it is properly set. |
Burglarproof & snap-proof |
When the signal circuit is cut, the system will be shut down automatically and shown “attacked”, the user cannot recover the problem. |
Antimagnetic |
When there is a magnetic attack, the system will be shut down automatically and on when the magnetic substance is away, the user need to insert user card to continue. |
Moisture-proof stand |
Moisture has no effect on the stand and the system will check if IC card is working properly. |
Self protection battery & valve |
Meter will be automatically switch on and off once for each month. |
Set limitation |
When the sum of purchasing amount in card and the usable amount in meter exceeds the maximum amount, the meter will automatically reject. |
Over-zero treatment |
When the valve is not functioning, the normal counting and over-zero counting will not be affected. User need to feedback to the computer software for processing. |
Pulse Moisture-proof |
The signal path will not be affected even they are attacked by moisture. Data will not be lost. |
Self checking |
Self check for mistakes in initializer, storage, card and so on. |
Usage |
Multi-meter card |
One client can use cold, hot and purified water meter. |
Checking, retrieval data |
When the meter is broken and needed to be changed, The checking and retrieval card can transfer the history to the computer. |
Initialization |
The initialization card can clear all history and set all parameters again. |
Checking card |
When the meter is not function properly, the checking card can test if the system is working. |
Reissue |
Cards can be reissued when the users lost their cards |
Convenient meter taking |
Meter taking without going into users' house, collect data at any moment and understand the status of exterior implement |
