Photoelectric Directing Reading Prepaid Gas Meter for the AMR/AMI System
Working Theory and Features:
- Measures gas volume by using pressure difference between inlet port, outlet to push membrane, and double crank incessant movement
- Material: Top quality cold-rolled steel plate and imported high quality plastic
- Used for one-shot forming measuring unit with parts reduction
- Eddy slide valve, low friction, and high sensitivity
- Wearable synthetic resin for material of valve base and lid
- GS series with well-connected design, production, and test
- Widely used for measurement of natural, artificial gas, and liquefied petroleum
Main Features:
. It can automatically measure water flow with CPU card or logic card
. LCD (liquid crystal display) and alarm
. The built-in ball valve and the driving motor works reliably and effectively
. Special technology ensures no worry about IC card copy
. Built-in solid data memory records all running data
. Anti-theft designs: Anti-magnetic interruption, power break protections
. Low energy consumption design

Maintain:
1. User cannot destroy the lead seal of gas meter, if any abnormal, please call gas company for checking.
2. Inspect the gas meter in regular period, the the abnormal situation can be found and handled on time.
3. When the battery is low, please call gas company for replace.
4. Gas meter belongs to measurement tool, it should follow relative rules.
5. About the situation for difference between electric part and machinery part. According to relative rules, for the smart meter with both electric part and machinery in gas meter, if damages of electric part which cause difference between electric part and machinery part, choose the machinery part valve.
6. About negative problem. When the rest amount in gas meter is 0, and user can still use water because of problems of unclosed valve, the gas meter will record the consumption, and so “Rest Amount ” display negative, means for user’s overdraw consumption. When user purchase at next time, it should be reduced at first, no cost loss for manage department. If individual user didn’t purchase gas for a long time or there is abnormal in consumption, the manage department should go for checking on time. Loss which caused by neglect of checking and managing, the supplier won’t take responsibility for that.
