科恩科KNKE高精度電磁流量計是一種用於(yu) 測量液體(ti) 流量的儀(yi) 器。它基於(yu) 法拉第電磁感應定律,通過測量液體(ti) 通過導電管道時產(chan) 生的電磁感應信號來確定液體(ti) 流量。
高精度電磁流量計的主要優(you) 點是精度高、穩定性好、不受液體(ti) 密度、溫度、壓力等參數的影響,並且不需要使用流體(ti) 控製元件,因此不會(hui) 對流體(ti) 造成任何阻力或能量損失。此外,由於(yu) 它是基於(yu) 電磁感應的,因此它還可以測量導電液體(ti) 的流量,如水、汙水、酸、堿、鹽水等。
高精度電磁流量計通常由傳(chuan) 感器和信號處理器兩(liang) 部分組成。傳(chuan) 感器包括液體(ti) 流經的導電管道和安裝在管道周圍的電磁線圈,信號處理器則負責接收傳(chuan) 感器產(chan) 生的信號並將其轉換為(wei) 數字信號輸出。
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.
