Main measures for gas flow meter meter management

The measurement accuracy is critical, and only the high-precision metering device is far less than enough, it is necessary to improve the management level of the entire meter. Accurate measurement of metering instruments, stable operation is the basis for controlling supply and marketing, and is an important means of controlling supply and market in gas business enterprises. Through metrology management, the supply and market is controlled, first, the management of the metering instrument should be started, the main measures are as follows: (1) The volume correction instrument is an electronic instrument and there is a possibility of failure. The flowmeter that requires the user with the amount of gas ≥ 50m3 / h must have a base table counter to ensure the integrity and validity of the measurement. (2) Focus on temperature and pressure correction, requiring flow meters to be compensated for temperature and pressure. (3) Considering the flowmeter from the temperature pressure sensor is an electronic instrument, there is a possibility of failure, focusing on the flowmeter temperature, the transfer and comparison of pressure data, and the discovery data is abnormal, the maintenance must be maintained in time. (4) Strengthen the supervision of the client meter meter. Establish a user gas equipment account, regular security, meter reading, investigate private and privacy, and the instrument use is not normal, and timely solve the meter does not match. (5) Using the SCADA system and the industrial and commercial remote monitoring system, remote real-time monitoring of the flowmeter state of the door station and large industrial and commercial users, which is convenient for timely discovery. Regularly use the photovoltaic connector to transfer data, through the analysis of historical data, judgment the time and cause of the fault, and timely discovery the time period and the amount of gas that is maliciously stolen. (6) In order to ensure the uninterruptible measurement, the gas company should maintain a certain number of turn-on forms, which can be replaced in time when the meter fails. (7) Focus on the cycle verification and cleaning of the flowmeter, timely discovery and processing flowmeter dust deposition, reverse and overload, to ensure the normal operation of the flowmeter. (8) Strictly put the inspection and acceptance, and unable to ventilate the instrument that does not meet the requirements. In addition, industrial and commercial users of gas compared to residential users, the use of smart meters more, large gas consumption, with irregular gas, so we must focus on industrial and commercial users of gas measuring instruments of management.
