Design of Flow Meter Based on IEEE754 Standard

ZHOU Jialing;Mechanical Vocational and Technical College;  
In view of existing situation that frequency signal and analog voltage signal are measured by many flowmeters,a standard gauge supported for remote real-time monitoring was developed based on the Modbus protocol. Half duplex communication network is composed of RS-485 with the feature of differential signal negative logic. Flow meter data in the form of IEEE754 single precision floating-point standard will be transmitted to the host computer in the datalink layer of the OSI model based on Modbus protocol. PC monitoring system is programmed by the Kingview,supporting remote access,data overrun alarm,parameter setting and other functions. The experimental results show that: the standard flow meter design is feasible,the debugging result is consistent with the expected,has the wide input voltage range,strong anti-interference ability,stable and reliable communication etc.
