The SR-510 online fluorescent tracer sensor was made to get reliable measurements of PTSA water content. A short-wavelength excitation diode, a bespoke filter, and automatic correction for turbidity and chromaticity are all used. Its new design keeps dirt from building up and makes it easier to take apart and clean. It is stable when it comes to measuring and doesn’t get in the way. Online monitoring of fluorescent agent concentration helps with drug addition and process control in circulating water and water treatment processes.

Featured Applications
- In industrial circulating water systems, keep an eye on the amount of PTSA fluorescent agent, guide the addition of corrosion and scale inhibitors and other chemicals, and make sure the right amount of chemicals is added;
- Using fluorescence tracing to keep an eye on clean water, recycled water, and other processes, evaluating water flow and chemical mixing, and improving process parameters;
- Checking the levels of fluorescent agents in central air conditioning and industrial cooling water pipelines to make sure that the water treatment agents are working and to stop equipment from corroding and scaling;
- Municipal/chemical water treatment: Tracer detection lets you keep an eye on the state and quality of the process in real time.
Core functions and operations
Installation requirements
- Customized DN25 three-way installation, with standard internal wires, can be directly connected to the water intake circuit/circulating water pipeline;
- It is recommended to use a low inlet and high outlet water flow method, so that the water sample flows through the sensor from bottom to top to ensure sufficient measurement;
- Valves should be equipped at the three-way inlet to regulate the flow rate of the water sample, controlling the flow rate between 100-500L/h (recommended 200-500L/h);
- Outdoor installation requires sun protection and shielding to prevent direct sunlight from affecting measurement accuracy.
Wiring Definition
The sensor cable is a five colored wire with clear wire sequence, which can be directly connected to the controller/PLC. The 24V power supply ground and 4-20mA output ground are internally short circuited and can share the same grounding:
- Red: Power Supply+
- Blue: Power Supply-
- Yellow: 485-A
- Green: 485-B
- Black: 4-20mA positive pole
Note: Cables that do not require connection should be properly sealed with electrical tape to prevent short circuits; The external power supply needs to ensure a voltage within the range of 23-25VDC.
Daily maintenance and calibration
Routine maintenance
- Regular cleaning: Clean the front quartz glass piece once a month with a soft bristled brush to remove debris and accumulation; If the contamination is severe, 1% citric acid weak acid can be used for cleaning. It is forbidden to use organic solvents or strong acids for cleaning to avoid damaging the filter and glass sheet;
- Storage requirements: Avoid long-term storage in an environment above 37 ℃, and store in a dry, room temperature environment when idle;
- Cable protection: Make sure to waterproof the cable joints to avoid soaking in sewage and prevent signal failures.
Calibration operation
- Regularly use a fluorescent agent PTSA standard solution of 20-100ppb to detect sensor readings and check for any deviations;
- If the reading deviation exceeds the allowable range, rinse the measuring end of the sensor with deionized water first, and then recalibrate with standard PTSA solution to ensure measurement accuracy.
