摘要：The invention discloses a method and a device for detecting the drainage flow rate of a hidden water tank. The method of real-time communication between electronic scale load-bearing device and profinet is proposed to realize the detection of drainage flow. The device consists of electronic scale load-bearing device, high-speed electronic scale acquisition module, PLC lower computer, touch screen man-machine interaction layer and so on. The device achieves fast detection response time and ensures sample integrity. It also avoid the problem of slow response of the input type liquid level sensor and inconvenient installation of magnetostrictive liquid level sensor.
