1.With new sensor, the initial flow rate is low, the pressure loss is small, the anti-vibration and anti-pulse fluidity is not easy to corrode, the reliability is good and the service life is long.
2.It adopts a new integrated chip with high performance and high precision, powerful function and superior performance.
3.It adopts advanced micro power consumption high and new technology, the whole machine power consumption is low. It can be operated by internal battery for a long time and by external power supply.
4.According to the flow frequency signal, the instrument series can be automatically modified in eight segments at most, and the calculation accuracy of the instrument can be improved according to the needs of users.
5.It adopts the EEPROM data storage technology, it has the function of storing and querying historical data, and three kinds of historical data recording methods can be chosen by users.
6.Flow meter head can rotate 180℃, easy to install and use.
7.High accuracy, it can be up to ±1.5%R, ±1.0%R.
8.Good repeatability, short-term repeatability can reach 0.05% R~0.2% R. It is precisely because of good repeatability, such as regular calibration or on-line calibration can get extremely high accuracy, it is the preferred flow meter in trade settlement.
9.The temperature, pressure and flow rate of the measured gas can be detected, and the flow rate can be automatically tracked and compensated, and the gas flow rate under the standard transition state (pn=101.325 kpa,Tnpn=293.15 k) can be displayed. The data of temperature, pressure, time, date and so on can be also queried in real time.
