★適用場合需要將高溫介質與變送器隔離●對變送器敏感元件有魔蝕性作用。懸浮液體或高粘度介質密封壓力容器液位測量更換被測介質需要嚴格凈化測量頭●測量頭必須保持清潔衛生。被測介質由于環境或流程溫度變化而固化或    目前水產養殖中一般是將沒有處理的廢水直接排放到河流里，造成嚴重的污染環境，有的設置有廢水處理裝置，廢水處理裝置上安裝有管道，在管道內安裝有過濾片可對廢水中較大的顆粒物進行過濾,例如對蝦糞進行過濾，但是在長期使用過程中，固體雜質會將過濾片的孔慢慢堵塞，造成廢水無法流淌現象，只能靠人工進行拆除清洗，費時費力，不便于操作。
The high temperature medium should be isolated from the transmitter in the application occasion ● it has the magical effect on the sensitive elements of the transmitter. Liquid level measurement of sealed pressure vessel with suspended liquid or high viscosity medium. The measuring head must be cleaned strictly when changing the measured medium ● the measuring head must be kept clean. The measured medium is solidified due to the change of environment or process temperature. At present, the untreated wastewater is directly discharged into the river in aquaculture, resulting in serious environmental pollution. Some of them are equipped with wastewater treatment devices, and pipes are installed on the wastewater treatment devices, and filters are installed in the pipes to filter the larger particles in the wastewater, For example, shrimp feces are filtered, but in the long-term use process, solid impurities will slowly block the hole of the filter, resulting in waste water can not flow phenomenon, can only rely on manual removal and cleaning, time-consuming and laborious, not easy to operate.

的穩定性、精度、可靠性非常重要，具有工作可靠、性能穩定、安裝使用方便、體積小、重量輕、性能價格比高等點。廣泛應用于各種工業自控環境，涉及水利水電、鐵路交通、智能建筑、生產自控、航空航天、軍工、石化、油井、電力、船舶、機床、管道等眾多行業，適用于測量液體、氣體或蒸汽的液位、密度和壓力，然后將壓力信號轉變成4～20mADC信號輸出。
The stability, precision and reliability are very important, with reliable work, stable performance, convenient installation and use, small volume, light weight, high performance price ratio. It is widely used in a variety of industrial automatic control environment, involving water conservancy and hydropower, railway transportation, intelligent building, production automation, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries. It is suitable for measuring the liquid level, density and pressure of liquid, gas or steam, and then converting the pressure signal into 4 ~ 20mADC signal output.
一種過濾裝置，包括相互連接的進水管與出水管，所述出水管靠近進水管的端部散裝有過濾片，所述進水管與出水管之間安裝有連接筒，所述連接筒豎直設置有滑筒，所述滑筒內安裝有可沿滑筒移動的刮板，所述刮板與過濾片位置相對應。
A filtering device includes an inlet pipe and a water outlet pipe which are connected with each other. The end of the water outlet pipe is close to the water inlet pipe in bulk. A connecting cylinder is installed between the water inlet pipe and the water outlet pipe. The connecting cylinder is vertically provided with a sliding cylinder, and the scraper which can move along the sliding cylinder is installed in the sliding cylinder, and the position of the scraper is corresponding to the position of the filter sheet.
當過濾片在長期使用過程中，過濾孔會粘附雜物會逐漸將過濾孔堵塞，通過上述設置，通過刮板沿滑筒移動可將過濾片上的附著物清除掉，保證過濾片的正常使用。
When the filter is used for a long time, impurities will adhere to the filter hole, which will gradually block the filter hole. Through the above settings, the attachment on the filter can be removed by moving the scraper along the sliding cylinder, so as to ensure the normal use of the filter.
