Introduction:
Equipped with our companyí»s code controller, base meters are bought abroad to realize the prepaid and control functions, thus to achieve the automatic control of different functions of this new type of gas meter.
Range of application:
This product can be applied to the measurement of gas, natural gas, liquefied petroleum gas and other non-corrosive gases in the city.
Main features:
Automatic prepaid function: charging before using of it, water meter residual capacity= the original gas + newly purchased gas
Auto-control function: switching the gas path automatically according to the payments and gas situation.
Real time computation function: measuring on the real time and display the stock value, closing gas source automatically when the purchased gas is used up.
Power-down memory function: solid state recorder is internally installed and the data will be permanently preserved.
Status display function: displaying the amount of newly charged gas, the remaining stock and cumulative use, as well as low-voltage state etc.
Prompting function: warning when the remaining gas is used to the set value or other functions are out of work.
Overdrawing function: able to set a certain overdraft gas according to the user needs
Automatic alarm function: when the voltage is lower than certain point, alarm system will be operated and the battery must be replaced within 72 hours, otherwise, it will automatically shut down the gas resources.
Anti-gas-larceny function: shut down the gas supply automatically when there are theft of gas or illegal operations

Introduction The series of products are encoded and decoded by a computer algorithm based on encryption and decryption rules. The user inputs the 8-bit code that produced by the management system to realize the purchases recharge. On account of using a plain language input with no carrier, the user can go to the places designated by operating companies to buy code directly or get the code by phone. With 8-bit password, the users can recharge by themselves without considering time and space constraints, and it is simple and convenient to use. Operating units can manage hundreds of thousands of users with little manpower and equipment, and complete manage service fees and charges without leaving home, which puts an end to the phenomenon of the arrears. Range of application To measure the cold water that flows through water pipe and control of water fees.

WF30-12 Cone-shaped Flow meter Pipe type Specification: Cone-shaped flow meter is a new-style high precision flow sensor who can measure all kinds of media. The cone piece throttle hanging over the pipeline center can baffle the fluid, which forms into differential pressure at the up and downriver of the cone. The p corresponds with the media flux, and there are two pressure ports located at the forth and after of the flow sensor respectively positive pressure port and negative pressure port. 1. Apply to: air, liquid & steam in pipe. 2. Pipe diameter: 15mm~2000mm or more. 3. Pressure grade: pn0.25-42.0 4. Accuracy: +0.5% of measure value 5. Turndown: more than 10:1 6. Repeatability: +0.1% 7. Standard betas: 0.450-0.850 8. Pressure loss: % of differential pressure, varies with beta ratio. 9. Installation: 0-3d upstream, 0-1d downstream.
