The working principle of the membrane dissolved oxygen method is different from that of the fluorescence method. The common membrane dissolved oxygen meter mostly uses a diaphragm electrode as a transducer to convert the dissolved oxygen concentration (actually oxygen partial pressure) into an electrical signal, which is then amplified and adjusted ( Including salinity, temperature compensation), displayed by analog-to-digital conversion. There are two types of practical membrane electrodes for dissolved oxygen meters: polarographic (Polarography) and galvanic cell (Galvanic Cell). Polarography: In the electrode, a gold (Au) ring or a platinum (Pt) gold ring is used as the cathode; silver-silver chloride (or mercury-mercurous chloride) is used as the anode. The electrolyte is potassium chloride solution. The outer surface of the cathode is covered with an oxygen-permeable film. The film can adopt breathable materials such as polytetrafluoroethylene, polyvinyl chloride, polyethylene, silicone rubber, etc. The fluorescence dissolved oxygen sensor is based on the principle of quenching active fluorescence by specific substances in physics. The blue light from a light-emitting diode (LED) shines on the fluorescent material on the inner surface of the fluorescent cap, and the fluorescent material on the inner surface is excited to emit red light. By detecting the phase difference between the red light and the blue light, and comparing with the internal calibration value Comparison, so as to calculate the concentration of oxygen molecules, and output the final value after automatic compensation of temperature and air pressure. Fluorescence dissolved oxygen analyzers have more advantages. The membrane method is easily covered by sludge, and the sludge has little effect on the fluorescence DO measurement. The fluorescence method for measuring dissolved oxygen does have the advantages of faster response and longer use time than the polarographic method, but the price of the fluorescence method dissolved oxygen meter is more expensive. Advantages of Fluorescence Dissolved Oxygen Meter over Membrane Method The traditional membrane dissolved oxygen meter needs to change and clean the probe frequently due to the membrane and electrolyte, and the data is easy to drift. Fluorescence dissolved oxygen measurement does not require frequent cleaning of the probe, the data is stable, and the measurement response time is fast. The effect is to save energy and ensure the degradation effect. In summary, the fluorescence dissolved oxygen analysis has the following advantages. 1. No calibration required. Because it is designed by fluorescence method. Therefore, calibration is not required, which greatly reduces the maintenance workload during instrument use. 2. The measurement result is stable. The measurement of dissolved oxygen by fluorescence method is more stable because it does not consume any substance and does not consume dissolved oxygen in water during the measurement process. 3. Reduce cleaning frequency. The traditional membrane method needs to be cleaned frequently, otherwise it will seriously affect the penetration of oxygen and thus affect the measurement. The fluorescence method does not require high cleaning of the probe, just wipe the fluorescent cap regularly. 4. Low maintenance. Because the fluorescence method does not require calibration, frequent calibration, replacement of membrane (RO membrane), and frequent cleaning, the amount of maintenance after installation and use is very small. 5. No interference. Changes in pH value, chemical substances contained in sewage, H2S, heavy metals, etc. will not interfere with the measurement. In addition, it is also oxidizing and may be measured as oxygen by ordinary dissolved oxygen electrodes; carbon dioxide entering the electrolyte will The impact on the measurement is mainly to change the conductivity of the electrolyte, and the LDO has no electrolyte, so it will not be affected by carbon dioxide. 6. Fast response time. Fluorescent dissolved oxygen responds as soon as it comes into contact with water, and the time is very short. 7. No need for polarization time. Since no electrodes are used, there is no problem of polarization.

Understanding Drinking Water Distribution Systems

Before delving into the specifics of real-time tester monitoring, it's essential to understand the basics of drinking water distribution systems. These intricate networks are responsible for transporting water from treatment facilities to homes and businesses. The journey of treated water through pipes and reservoirs is fraught with potential threats to its quality, such as contamination, corrosion, and biofilm formation.

A typical drinking water distribution system involves several key components including pipes, storage tanks, pumps, and valves, each playing a critical role in ensuring that clean and safe water reaches the end user. Pipelines can extend over vast distances and traverse different environments, which may pose varying contamination risks. Tanks and reservoirs, often exposed to atmospheric conditions, can also be points of contamination. Not to mention, aging infrastructure poses its own sets of challenges, including leaks and bursts that can introduce harmful substances into drinking water.

Lastly, the well-being of any distribution system hinges upon timely and effective maintenance, but traditional inspection methods are not always up to the task. Manual inspections and periodic water quality testing, while useful, are reactive methods that detect issues only after they have had an impact. Hence, there is an increasing need for more proactive and real-time monitoring solutions.

The Role of Real-Time Tester Monitoring

Real-time tester monitoring takes water quality management to a new level by providing continuous, instantaneous data about various parameters of the water supply. These advanced systems employ a range of sensors to measure variables such as pH, temperature, turbidity, chlorine levels, and the presence of contaminants.

One of the most significant advantages of real-time tester monitoring is its ability to provide immediate feedback. This allows for quicker responses to any detected anomalies, significantly minimizing the time during which potentially contaminated water might be distributed. For instance, if a sensor detects an unusual spike in chlorine levels, an alert can be generated instantly, prompting water managers to investigate and rectify the situation before it escalates.

Moreover, real-time monitoring systems can be integrated with centralized control systems, enabling remote surveillance and management of water quality. This integration ensures that technicians can access real-time data from various parts of the distribution system, all from a single interface.
