CHANGZHOU CHENGFENG FLOWMETER CO.,LTD was established in 1979,at the begining our company named as Qinfeng Flow meter.we are the professional manufacturer of flowmeters,thermometers,liquid level meters,transmitters and so on.The main products are contain of LZB/LZJ(-F)glass tube flow meter,LZB-W(B)micro type glass tube flow meters,G.R.F10/20/30 glass tube flow meters,LZZ/LZD(-F)metal tube flow meters,organism panel type purified flow meters,UHC magnetic flap liquid level meters,LUGB/LUCB vortex street flow transmitter,LDG electromagnetic flowmeters,LWGY/LWY turbine flowmeters,WSS series bimetallic thermometer and so on about five series and five hundred kinds products.
CF series intelligent digital pressure / differential pressure transmitter is an intelligent digital instrument of multi functions independently developed by the company through integrating our many-year industrial manufacturing experience; it is elaborately designed by combining with advanced single chip computer technology and sensor digital conversion technology on the basis of capacitor sensor technology that is internationally advanced, proven, and reliable.
The instrument is cored with a 16-bit single chip microcomputer, whose powerful functions and high speed computing capability strongly guarantee the excellent quality of the transmitter. The design, as a whole, is with a view to performance reliability, stability, high precision and intelligentization, which fulfill the requirements of industrial sites nowadays that get demanding day by day. Therefore, the software is applied with digital signal processing technology which provides the instrument with excellent performance of resisting disturbance and zero point stability as well as zero point stability self tracing capability (ZSC) and temperature self compensation (TSC) capability.
