LZYN Series Coriolis Mass Flowmeter (hereafter we call LZYN) is designed according to the Coriolis Principle. It can be widely used for the process detecting and custody transfer/fiscal unit in many industries such as petroleum, petrochemical industry, pharmacy, paper making, food and energy etc.. As a fairly advanced kind of flow measuring instrument, it has been paid attention by the circle of measurement and accepted by many customers home and abroad. Principle LZYN is designed according to the principle of Coriolis force. Under the alternating current effect, the magnet and coil installed on the measuring tube will make two parallel measuring tubes vibrate according to some fixed frequency. Once there is flow passing through the pipes, Coriolis force will give rise to deflection (phase shift) on the vibration of two pipes and the deflection of vibration is directly proportional to the mass flow of fluid. Pick up them and the mass flowrate could be calculated. The vibration frequency of measuring tube is determined by the total mass of measuring tube and inner fluid. When the fluid density changes, the vibration frequency of measuring tube will be also changed, as a result, the fluid density can be calculated. The temperature transducer installed in the pipeline can pick up the fluid temperature on time under the coordination of measuring circuit. Feature 3. 1 Digital transmitter Feature Comparing with traditional analog circuit and analog transmitter, digital circuit and digital transmitter has the following obvious merits: 3.1.1 The DSP chip is the core of digital transmitter for LZYN. As we know, the techniques of Digital Signal
