采用了国际先进的Honeywell无接触检测磁场角度变化的磁测传感器、并配以Motorola微处理系统，可实现液晶指示、累积、远传输出(4-20Ma)、脉冲输出、上下限报警输出等功能，该型智能信号变送器具有及高的精度和可靠性，完全可以取代进口同类型仪表，且具有性价比高、多参数标定、掉电保护等到特点。 The metal tube float flow meter uses the international advanced Honeywell non-contact magnetic field sensor to detect the change of the magnetic field angle, and is equipped with a Motorola micro-processing system. Lower limit alarm output and other functions, this type of intelligent signal transmitter has high accuracy and reliability, can completely replace imported instruments of the same type, and has cost-effective, multi-parameter calibration, power failure protection and other features. Metal tube float flowmeter is an indispensable instrument in the industrial society. He represents our advanced industrial space and advanced society. To better understand the metal float flowmeter requires more time to invest in research Of course, it is convenient and thorough to understand its use, usage methods, etc. We need to invest in the corresponding factories to learn and practice. I hope that in the future we will have a more comprehensive understanding of the advanced equipment of the society.
