Copper is an important metal that is used in many fields, such as alloy, dye, pipeline, circuit and so on. Copper salt can inhibit the growth of hydroplankton and algae. When the cupric ion concentration exceeds 1mg/L in drinking water, it will be bitter.
Ultrasonic open-channel flowmeter and measuring weir slot are used together to measure the water flow in the open channel. It is mainly used to measure the flow in sewage plant, enterprise and public institution discharge outlet and urban sewer. The instrument takes the advantage of contactless way as ultrasonic goes through the air, so it keeps higher reliability than other instruments when measuring sticky and corrosive liquid.
EST-2000 type data collection and transmission device (hereinafter referred to as data collection device) is a high-performance data collection and transmission apparatus focusing on online supervision (monitoring) system of different kinds of pollution source. The embedded Linux operating system and real-time database in the system completely conform to HJ/T212-2005 Data Transmission Standard of Pollution Source Online Supervision (Monitoring) System. Meanwhile, the system keeps strong technology expansibility and convenient for installation and maintenance.
The apparatus can achieve real time monitoring to primary instrument. It is always online. It connects with flowmeter, COD, PH meter, the measuring meter of ammonia nitrogen, residual chlorine and smoke through analog signal interface, digital signal interface and RS232/485 interface. This makes it convenient for primary instrument monitoring, and meets the pollution source online monitoring requirement of environment fields, national control, provincial control and municipal control.
