PROBLEM TO BE SOLVED: To provide a liquid sprinkler which can be suitably used not only for accurately grasp an instantaneous flow and an integrated flow, but also, for measuring other various useful results.SOLUTION: This liquid sprinkler 1 is equipped with a manual faucet 4 which switches a liquid to be discharged from a sprinkling liquid tank 2 by a pump 3, to the sprinkling side A or the return side B to the sprinkling liquid tank 2 and vice versa. In addition, the liquid sprinkler includes a flow sensor 5 arranged between the pump 3 and the faucet 4, detection means 6 and 7 which detect whether or not the faucet 4 is switched to the sprinkling side A and a control means 8 which performs a predetermined arithmetic operation based on the detection results of the flow sensor 5 and the detection results of the detection means 6 and 7. The detection means and are such as a pressure sensor 6 arranged on the sprinkling side and a limit switch 7 which opens/closes by operating the switching operation member 20 of the faucet 4.COPYRIGHT: (C)2011,JPO&INPIT【課題】 瞬間流量や積算流量の把握は勿論、それに加えて他の種々の効果も得られる液体散布装置を提案する。【解決手段】 散布液タンク2からポンプ3により吐出される液体を散布側Aと前記散布液タンク3への戻し側Bとに切換えるための手動式のコック4を備える液体散布装置1であって、前記ポンプ3と前記コック4の間に流量センサ5が配設され、前記コック4が前記散布側Aへ切り換えられているか否かを検知する検知手段6,7と、前記流量センサ5による検知結果と前記検知手段6,7による検知結果を受けて所定の演算を行う制御手段8を備える。前記検知手段としては、前記散布側に配設される圧力センサ6や、前記コック4の切換操作部材20の操作により開閉するリミットスイッチ7を挙げることができる。【選択図】 図1
