摘  要:
流量计是用以测量管路中流体流量(单位时间内通过的流体体积)的仪表。超声波在流动的流体中传播时就载上流体流速的信息,超声波技术是由测量横过渠道的超声波传播时间来计算流速的;电磁流量计是根据法拉第电磁感应定律制成的,用来测量导电液体体积流量的仪表。测流的电磁技术是利用导电的水流中人工建立的磁场,然后测量横跨水流两边的合成电位差。二者均在农田灌溉中有着广泛的应用前景。

摘  要:
The flowmeter is a kind of meters that is used to mesure liquid flow in the pipeline.Altrasonic contain the information of velocity of flow of liquid when it transmits in flowing liquid,the technology of altrasonic computes velocity of flow depending on mesuring transmitting time of altrasonic across the channel;The electromagnetic flowmeter is a kind of meters that depend on Faraday law of electromagnetic induction and is used to mesure volume flow of electric liquid,electromagnetic technique used in mesuring velocity of flow makes use of magnetic field built artificially in flow and mesures complex potential difference across the flow.Both of them will be widely used in farm irrigation.
