Flow Meter Valve

Flow Meter Valve, Flow Measurement Instrument, Chemical Flowmeter Valve 1.1 Introduction K Series Mass Flowmeter (hereafter we call K) is designed according to the Coriolis Principle.It has been widely for the process detecting and custody transfer/fiscal unit in many industries such as petroleum, petroleum and chemical,chemical industry, pharmacy, paper making, food and energy, and so on. As a fairly advanced kind of flow measurement instrument, it has been paid attention by the circle of measure- ment measurement and accepted by many customers home and abroad. K 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 changing, as a result, the fluid density can be calculated. The temperature sensor installed in the pipeline can pick up the fluid temperature on time under the coordination of measuring circuit. Comparing with the traditional flow measurement method, K has following obvious merits:1.3.1. Enable to measure directly mass flow rate of fluid in the pipeline without changing any parameters, which avoids the some measurement error of intermediate links. Its mass flowrate can be high accuracy and good repeatabi
