Prepayment of vortex flowmeter in zld-ii metering management center of steam pre charging system

Qingdao Zhiyuan instrument steam pre charging system mainly consists of the following components:
Metering part: flowmeter, pressure transmitter, temperature sensor, flow totalizer, etc
Prepayment part: IC card prepayment control box (IC card prepayment controller, lightning protection device, switching power supply, instrument UPS power supply, 4G communication module), intelligent electric valve, etc
Master station: upper computer server, computer or cloud platform, prepaid system software, data acquisition system software, database software, IC card recharge software, IC card reader, etc
In the management room, the whole system can be seen at a glance with the network browsing function, and the 24-hour and 24-hour operation of the heat supply network can be realized
All physical quantity data in the system are displayed on the screen
With * * * informing the user of steam parameters and pipeline operation parameters, the fault can reach *, and the long transmission distance can reach 1200 meters, which can reliably meet the needs of low-level data acquisition and transmission, At the same time, it also helps to reduce the distributed capacitance between the two 485 communication lines and the capacitance from around the communication line
Basic functions of vortex flowmeter prepayment in zld-ii metering management center of steam pre charging system: ⑴ instrument working condition data, instrument parameters, steam purchase volume and other parameters of each user can be uploaded to the central server through GPRS / CDMA transmission mode, and can be queried through computer or real-time
(2) it has the function of real-time data and curve query, as well as routine systems such as daily report, monthly report and annual report
