Information

 

Product Description:

The FGWQ-2000 series of water quality monitoring micro-stations takes miniaturized instruments as the core, and uses modern automation and communication technology to integrate the water quality monitoring system into an outdoor cabinet. It is mainly aimed at new online water quality monitoring products that have emerged as the times require high density, low cost, and high frequency in application scenarios such as environmental protection, water conservancy or environmental governance. Compared with the traditional automatic water quality monitoring station, the micro-station has obvious advantages. It adopts a customized movable monitoring cabinet with beautiful appearance, convenient relocation and low construction cost. The equipment has the advantages of high integration, complete functions, reliable operation, small footprint, no need for land acquisition, short construction period and low investment, and is suitable for a wide range of locations. It can realize the functions of river length assessment, pollution tracing, water quality evaluation and water quality early warning.

 

Product Composition

The miniature water quality automatic monitoring station is composed of water collection unit, pretreatment and water distribution unit, analysis unit, data acquisition and transmission unit, control unit, auxiliary unit, etc., with optional quality control unit and remote monitoring platform.

Water collection unit
Water collection unit Based on the preliminary investigation and understanding, according to the site conditions, combined with the company's previous experience in similar projects, put forward an economical and applicable water extraction plan. The water collection unit that can automatically and continuously work in synchronization with the entire system provides reliable and effective water samples to the system.
Water distribution pretreatment unit Multi-stage pretreatment is used to meet the pretreatment requirements of different analysis modules for water samples. Including the static sedimentation of raw water, precision filtration and water distribution, etc. Part of the water sample provided by the water collection unit enters the five-parameter flow cell (note: the five-parameter meter water does not require sedimentation and filtration, and the sample pump is directly supplied to the flow cell for testing); a part of the raw water flows into the sedimentation after removing large particles by the filter In the pool, buffer and settle the sand; after filtering, enter the sampling cup for analysis instrument use.
Control unit and data acquisition and transmission unit The control unit is composed of an industrial computer, a PLC programmable controller, and a wireless or wired transmission module. The system realizes instrument measurement control through industrial computer PC software, and realizes system water collection and pump valve control through PLC; industrial computer can upload test results and instrument status to the information platform through wired network, GPRS, 3G/4G wireless network.
