Multi channel portable paperless recorder modelAbandoning the recording pen and paper used in traditional paper-based recorders, the quality of the recorder itself has been improved, the stability and reliability of the recorder have been enhanced, and more importantly, the operating cost of the recorder has been reduced.

Multi channel portable paperless recorder modelFor TFT true color LCD display. The instrument has fully isolated input and can be matched with various flow meters such as electromagnetic, vortex street, orifice plate, turbine, etc. It calculates the ultra compression system of natural gas in real-time online based on the molar composition of natural gas, pipeline temperature and pressure, and automatically compensates the fluid flow rate to the volume flow rate under industrial standard conditions (20 ℃, 0.101325MPa) (intelligent temperature and pressure compensation function). Support multi loop flow integration, with data processing and flow calculation cycles less than 1 second. It can provide functions such as transmission, communication, printing, alarm, and power feeding. The instrument has powerful display functions, including high-precision bar chart display, real-time curve display, historical curve recall, alarm status display, and can directly query data for year, month, day, hour, minute, and second, making it fast and convenient. Using RS232 and RS485 communication and RS232 printing, standard MODBUS-RTU protocol, can be configured with professional software such as Kingview and MCGS. Data can be directly exported through any USB flash drive, which is plug and read without any operation; The analysis software can export data in EXCEL format or curve format and print directly.
