Filling the Monitoring Gap in Pipeline Networks to Secure the Influent Safety of Sewage Treatment Plants
In urban drainage systems, sewage pump stations are critical nodes connecting discharge sources to treatment plants. However, traditional pump stations often focus only on liquid level and flow rate, lacking perception of water quality changes. This leads to frequent threats from illegal dumping and influent shocks to downstream biological treatment systems.
YexSensor Core Values:
Full-Time Monitoring: Industrial-grade stability, 7×24 hour real-time feedback on pollutant concentrations, solving the problem of poor timeliness in manual sampling.
Standardized Integration: The entire product line features built-in RS485 (Modbus RTU) protocol, seamlessly connecting to various PLCs, RTUs, and cloud gateways.
Low-Maintenance Design: Equipped with automatic cleaning brush options and high-strength corrosion-resistant materials, significantly reducing the maintenance frequency at remote pump stations.
Overview: Transitioning from "Reactive Response" to "Proactive Perception"
Traditional environmental monitoring relies heavily on manual on-site sampling, a model that faces bottlenecks in modern urban management such as scattered data and poor spatial-temporal representation. Especially for sewage collection and transportation networks, water quality monitoring inside the pipeline network is almost a blank space.
Once unidentified high-concentration wastewater enters the sewage treatment plant through the pump station, if the plant's influent instruments are in a maintenance period or their range is exceeded, the consequences for the downstream activated sludge system would be catastrophic. YexSensor aims to establish an "Electronic Sentry" system covering the entire pipeline network. By pre-positioning water quality monitoring nodes at pump stations, management can accurately identify pollution sources, achieving early discovery, early warning, and early treatment of pollution incidents.

Core Advantage: Engineering-Grade Reliability
YexSensor understands that in sewage pump stations, the survival capability of a sensor is paramount.
1. Superior Hardware Protection
Utilizing 316L stainless steel or POM material, YexSensor probes achieve IP68 waterproof ratings. Internal circuits feature optocoupler isolation to withstand electromagnetic interference from high-power water pumps.
2. Innovative Self-Cleaning Logic
To solve the issue of oil and biofilm adhesion, our sensors offer integrated automatic scraping brushes. This physical cleaning mechanism extends manual maintenance cycles from weekly to quarterly.
Applications
Urban Sewage Pump Station Influent Monitoring: Real-time perception of pollutant changes to intercept illegal discharge.
Sewage Treatment Plant Influent Early Warning: Serving as the "Outpost" to initiate bypass cut-offs before severe shocks reach biological tanks.
Industrial Park Discharge Point Monitoring: 24/7 digital monitoring for high-pollution industries.
Smart River Chiefs & Black-Odor Water Remediation: Distributed monitoring points at urban river nodes.
Frequently Asked Questions (FAQ)
Q1: Does the YexSensor require a secondary meter (display controller)?
Not necessarily. Our sensors support direct RS485 output to PLCs or DTUs. We also provide integrated cabinets if on-site reading is required.
Q2: Will the sensor be damaged in high Suspended Solids (SS) environments?
No. Our SS sensors use wear-resistant windows and optional scrapers to effectively prevent sediment accumulation.
Q3: How long is the calibration cycle for the sensor?
In stable pump station environments, a comparative calibration is recommended every 3-6 months.
Q4: Which monitoring factors do you support?
We cover COD, Ammonia Nitrogen, Total Phosphorus, Total Nitrogen, SS, pH, DO, and Conductivity.
Q5: Is the protocol documentation complete?
Yes. We provide detailed Modbus register tables for seamless system integration.
Q6: How long can the sensor cable be extended?
Standard RS485 supports up to 1200 meters, though we recommend staying within 200 meters in noisy pump station environments.
Q7: Can materials be customized for strong corrosive chemicals?
Yes. Titanium alloy or full Teflon shells are available for extreme acid and alkali environments.
Q8: How to troubleshoot a lost connection underwater?
Check supply voltage (DC 12-24V), ensure 485 A/B lines are not reversed, and use a serial debugger to check for Modbus responses.
