科恩科KNKE高精度电磁流量计是一种用于测量液体流量的仪器。它基于法拉第电磁感应定律,通过测量液体通过导电管道时产生的电磁感应信号来确定液体流量。
高精度电磁流量计的主要优点是精度高、稳定性好、不受液体密度、温度、压力等参数的影响,并且不需要使用流体控制元件,因此不会对流体造成任何阻力或能量损失。此外,由于它是基于电磁感应的,因此它还可以测量导电液体的流量,如水、污水、酸、碱、盐水等。
高精度电磁流量计通常由传感器和信号处理器两部分组成。传感器包括液体流经的导电管道和安装在管道周围的电磁线圈,信号处理器则负责接收传感器产生的信号并将其转换为数字信号输出。
A high-precision electromagnetic flowmeter is an instrument used to measure the flow of liquids. It is based on Faraday's law of electromagnetic induction, which determines the liquid flow by measuring the electromagnetic induction signal generated when the conductive liquid passes through the pipeline.
The main advantages of a high-precision electromagnetic flowmeter are its high accuracy, good stability, and insensitivity to liquid density, temperature, pressure, and other parameters. Moreover, it does not require the use of flow control elements, so it will not cause any resistance or energy loss to the fluid. Additionally, because it is based on electromagnetic induction, it can also measure the flow of conductive liquids, such as water, sewage, acids, alkalis, brine, etc.
A high-precision electromagnetic flowmeter typically consists of a sensor and a signal processor. The sensor includes the conductive pipeline through which the liquid flows and the electromagnetic coils installed around the pipeline. The signal processor is responsible for receiving the signals generated by the sensor and converting them into digital signals for output.
