最近,四川省农能办有关业务人员,根据水压式沼气池内产生多少立方米的沼气就必然将同体积的料液压到水压间的原理,摸索出了一种从水压间中取水称重,再换算成沼气池产气量的新方法。这种方法,不用流量计,操作简单,准确可靠,易于被广大农村技术人员掌握。现将此法介绍如下: Recently, Sichuan Province, farmers can do business-related personnel, according to the number of cubic meters of biogas generated biogas biogas will inevitably be the same volume of material hydraulic pressure between the principle, worked out a water from the pressure in the water Heavy, and then converted into biogas production of gas a new method. This method, without the flow meter, simple operation, accurate and reliable, easy to grasp by the majority of rural technical staff. Now this method is as follows:
