Overview
Aquaculture water quality monitoring equipment requires a high-precision multi parameter monitoring system to ensure water quality stability. In addition to conventional parameters, special indicators such as residual chlorine need to be monitored. Monitoring sensors are installed at key nodes such as the inlet of circulating water and the outlet of biological filters to track the water purification effect in real time. The monitoring system has increased the utilization rate of water bodies to over 90% while reducing water resource consumption by 30%. Net cage aquaculture is located in an open water environment and is greatly affected by natural factors. Monitoring equipment needs to have anti wind and anti biological attachment characteristics. It is usually installed and fixed around the net cage using anchoring, with a focus on monitoring water flow velocity, dissolved oxygen, and water temperature. For example,
Product Details
Aquaculture water quality monitoring equipmentFor the requirement of water quality stability, a high-precision multi parameter monitoring system needs to be configured to monitor special indicators such as residual chlorine in addition to conventional parameters. Monitoring sensors are installed at key nodes such as the inlet of circulating water and the outlet of biological filters to track the water purification effect in real time. The monitoring system has increased the utilization rate of water bodies to over 90% while reducing water resource consumption by 30%. Net cage aquaculture is located in an open water environment and is greatly affected by natural factors. Monitoring equipment needs to have anti wind and anti biological attachment characteristics. It is usually installed and fixed around the net cage using anchoring, with a focus on monitoring water flow velocity, dissolved oxygen, and water temperature. For example, in the large yellow croaker cage aquaculture area along the coast of Fujian, the monitoring system combines meteorological data to achieve wind and wave warning, and transfers the cages to sheltered areas in advance, effectively reducing aquaculture losses during typhoon seasons.
