Anti-theft method for steam prepayment metering controller
During the use of steam, pay attention to the fact that they are paid according to the amount of use, so pay attention to this behavior in the appropriation of steam without going through the billing of the steam prepaid flow meter controller. How should we prevent this? What happened?
I. Commonly used methods 1. Electromagnetic attack interferes with the electromagnetic attack of the flowmeter controller, so that the flowmeter controller does not measure or reduce the measurement, so as to achieve the purpose of stealing gas.
2. The private bypass pipe or straight pipe is connected through the private bypass pipe and does not flow through the steam prepaid flow meter controller or part of the flow meter controller, so that the flow meter controller does not measure or reduce the measurement, so as to achieve the purpose of stealing gas; The flow meter controller does not measure and achieves the purpose of stealing air.
3. Destroy the measuring instrument. By destroying the measuring instrument, the steam prepaid flowmeter controller does not measure or reduce the measurement to achieve the purpose of stealing gas. The main means of destruction are: artificially obstruct the rotating parts of the instrument and do not refuel according to the standard; destroy the flow sensor and high-frequency flow signal module, destroy the pressure sensor and temperature sensor, destroy the volume corrector, modify the instrument coefficient, etc.
Second, the solution By strengthening daily inspections and other means, you can prevent the theft of private bypass or straight connection. For gas theft that damages measuring instruments and electromagnetic attacks, it is necessary to improve the anti-theft performance of the steam prepaid flow meter controller, strengthen the frequency of daily inspections, and use judicial power to prevent it if necessary.
The uncivilized behavior of using steam but bypassing the billing of steam prepaid flowmeter controllers not only harms the economic interests of gas companies, but also causes some dangerous hidden dangers due to their own connection technology.
