Hidden water tank drainage flow detection method and device

The invention discloses a hidden water tank drainage flow detection method and device. The hidden water tank drainage flow detection device comprises an electronic scale bearing device, an electronicscale acquisition module, a PLC lower computer and a touch screen man-machine interaction layer. The electronic scale bearing device comprises a base, a weighing sensor, a supporting plate, a supporting frame, a front clamping plate, a mounting plate, a pressing cylinder, a hidden water tank and a rear clamping plate; the electronic scale bearing device and the profinet real-time communication method are used for detecting the drainage flow, the detection response time is short, and meanwhile the sample integrity is guaranteed. The problem that the input type liquid level sensor is slow in response and the problem that the magnetostriction liquid level sensor is inconvenient to install are solved. 本发明公开了一种隐藏式水箱排水流量的检测方法及装置，包括电子秤承重装置、电子秤采集模块、PLC下位机、触摸屏人机互动层；其中电子秤承重装置包括底座、称重传感器、支撑板、支撑架、前装夹板、安装板、按压气缸、隐藏式水箱和后装夹板；本发明用电
