科氏力质量流量计介绍 什么是科氏力 Fc=科氏力 m= 质量 v = 质量流速 ?= 角速度 Fc = -2 m (? x v) 科氏力原理 If a person were standing at the center of a merry-goround and tried to walk in a straight line toward the edge, he or she would have to lean sideways against the Coriolis force to stay on line. The Coriolis force, Fc, can be calculated using the mass of the person′s body, M, the velocity of travel, V, toward the edge, and the angular velocity of the merry-go-round, ?. Fc = -2 m (? x v) TRIO-MASS DSP信号转换器 数据输入通过三个组态按键 通过磁棒输入 显示显示模块可按90°旋转 转换器表头旋转角度超过330° 科氏力质量流量计在各种行业的应用 TRIO-MASS DSP MC2 装配和安装 TRIO-MASS 装配和安装 TRIO-MASS can be installed vertical or horizontal the primary is to be installed in a rigid pipeline in case of strong pipeline vibrations, use elastic pipeline elements supports should be installed up- and downstream of the meter, (weight and influence of gas) if possible shut-off valves should be installed up- and downstream, (for zero adjustments) primary should not be installed in the vicinity of strong electromagnetic fields, (motors, transformers) fittings valves, gates and sigth glasses should not cavitate, TRIO-MASS does not require any flow conditioning primary should not come in contact with any other elements multiple flowmeter primaries in the same pipeline or installed in interconnected pipelines should be located far from one another, or, the pipeline must be ecoupled to prevent crosstalk at the outlet a back pressure of at least 0.2 bar must exist the primary should never be installed at the highest point in the system long drop lines downstream from the flowmeter primary should be avoided for fluids with gas content a verticalinstallation is recommended zero adjustments under operation conditions (completely filled meter, gas, operating temperature) TRIO-MASS 装配和安装 TRIO-MASS Assembly and Installation  support and elastic pipeline elements  TRIO-MASS 装配和安装  推荐安装方式 TRIO-MASS Assembly and InstallationHorizontal Installation
