Frequently Asked Questions (FAQ)
❓What measurement method does the Blue-Green Algae sensor use?
The Blue-Green Algae sensor (LMS-BGA100) uses fluorescent measurement technology. A specialized UV light source excites chlorophyll fluorescence in algae cells, which is then detected and converted into a cell concentration reading. This method effectively filters interference from suspended particles and water color.
❓What is the detection range of the Blue-Green Algae sensor?
The sensor measures blue-green algae concentrations from 0 to 2,000,000 cells/ml, with an accuracy of ±3% F.S. It also simultaneously measures water temperature in the range of 0–50℃ with an accuracy of ±0.5℃.
❓Does the sensor require regular chemical reagents or consumables?
No. The Blue-Green Algae sensor is designed to be completely reagent-free. It does not require any chemical reagents for operation, which eliminates secondary pollution risks, reduces running costs, and makes it an environmentally friendly solution for long-term water quality monitoring.
❓How does the sensor handle biofouling and maintenance in the field?
The sensor features an integrated self-cleaning wiper mechanism that automatically removes biofilm and debris from the optical surface. This greatly reduces the frequency of manual cleaning, making it suitable for long-term, unattended deployment in lakes, rivers, aquaculture ponds, and other aquatic environments.
❓What communication protocol does the sensor support, and how is it powered?
The sensor communicates via RS-485 using the MODBUS protocol, making it compatible with most SCADA systems, data loggers, and water quality monitoring platforms. It operates on a power supply of 9–24 VDC, with 12 VDC recommended for optimal performance.
❓In which applications is the Blue-Green Algae sensor most commonly used?
The sensor is widely used in environmental water quality monitoring (lakes, rivers, reservoirs), drinking water treatment plants, aquaculture facilities, coastal and marine monitoring programs, and scientific research related to eutrophication and climate change. Its 24/7 real-time monitoring capability makes it ideal for early warning systems for harmful algal bloom (HAB) detection.
