一种实现任意液位加料的方法

一种实现任意液位加料的方法，提供液位加料检测装置，其包括注料容器，水泵，压力传感器，以及控制仪，所述控制仪的计算公式为：P＝ρg h,P为液体压力，ρ为液态物料密度，g为重力常数，h为液面高度；在将待注入液态物料加入所述注料容器内前，先测量待注入液态物料的密度ρ；在加料过程中所述控制仪连续监测所述压力传感器反馈的压力值P，当所述压力传感器反馈的压力值P大于或等于所述控制仪自动计算出需要对应液位h下的压力P时,则控制仪给出信号，将所述水泵关停，反之，所述水泵向所述注料容器内继续加料。该实现任意液位加料的方法原理可靠，设定方便，安装简单方便，适用于各种反应容器，可以连续任意控制液位。 The invention relates to a method for realizing feeding at any liquid level, and provides a liquid level feeding detection device. The liquid level feeding detection device comprises a material injection container, a water pump, a pressure sensor and a controller; the calculation formula of the controller is that P=rhog h, wherein P is liquid pressure, rho is liquid material density, g is a gravity constant, and h is liquid level height; before a liquid material to be injected is added into the material injection container, the density rho of the liquid material to be injected is measured; in the feeding process, the controller continuously monitors the pressure value P fed back by the pressure sensor; when the pressure
