Instrument characteristics
●Using 128x64 resolution graphics lattice LCD, all Chinese interface, easy to operate;
●The display content is rich and comprehensive, including instantaneous flow rate, cumulative flow rate, temperature, pressure, engineering unit, compensation information, alarm information, real time curve, real time curve, historical curve, recording status, annual/monthly accumulation, power outage information, etc;
●With open square, small signal excision, 8 - segment broken line and other operational functions;
●A variety of engineering units are available for selection, and the meter automatically calculates the total according to the selected unit;
●It has the function of calculating flow compensation according to the change of temperature and pressure of the fluid: there are three inputs of flow, pressure and temperature at the same time, and the flow is automatically compensated inside the meter, which can eliminate the adverse effects of temperature and pressure changes on the measurement results.Among them,the superheated/saturated steam adopts iapws-97 formula with high calculation accuracy;
●2-point alarm output, used for flow, temperature, pressure,upper and lower limit alarm or cumulant preset output, can remember the last 6 alarm time, alarm mode;
●Fully transparent, high-speed and efficient network communication interface realizes complete data transmission and control between computer and instrument. The unique control power transfer function enables computer to directly control alarm output and transmission output of instrument;
●4M memory is used for the measurement record, which can record 260,000 times of data.Data can be traced through historical curves and read through communications;
●It has USB interface and can transfer recorded history data to U disk at any time;
●Good software platform, with the ability of secondary development, can meet the special functional requirements;
●The product has obtained the authoritative organization electromagnetic compatibility (EMC) inspection certificate.
