GCC-ULG Series Ultrasonic Level Meter in Wastewater Lift Station
⚡ 30% Energy Reduction · 45% Fewer Pump Starts · 8-Month ROI
A municipal wastewater treatment plant in Jiangsu Province replaced float switches and basic radar sensors with GCC-ULG series ultrasonic level meters across 8 lift stations. The result: precise pump control that eliminated dry running, reduced unnecessary pump cycles, and cut electricity consumption by 30% – saving over ¥280,000 annually.
🏭 Customer Background
A regional wastewater treatment facility serving a population of 500,000 operates 8 remote lift stations that pump influent to the main plant. Each station is equipped with 3 submersible pumps (2 duty, 1 standby) ranging from 30kW to 75kW. The plant's annual electricity cost for pumping exceeded ¥930,000, making energy efficiency a top priority.
⚠️ Challenges & Pain Points
Inefficient Pump Control: Traditional float switches provided only ON/OFF signals at fixed levels, causing pumps to run longer than necessary and start/stop frequently.
High Energy Waste: Pumps often ran at partial capacity due to poor level control, wasting up to 25% of energy.
Mechanical Wear: Excessive pump cycling (average 18 starts per day per pump) accelerated mechanical and electrical component wear.
Flooding Risk: Float switches occasionally stuck or failed, leading to wet well overflows and regulatory violations.
Maintenance Burden: Staff spent over 20 hours monthly cleaning and adjusting float switches, with annual replacement costs exceeding ¥50,000.
🔧 Our Solution
We installed GCC-ULG series ultrasonic level meters in all 8 lift stations, with the following key features:
Continuous 4-20mA Level Output: Provided real‑time level data to the PLC, enabling variable pump speed control and optimized staging.
Programmable Pump Sequencing: Level setpoints were configured to alternate pumps, equalize run hours, and minimize starts.
±2mm High Accuracy: Enabled precise control of pump activation and deactivation levels, reducing unnecessary runtime.
IP68 Waterproof & Corrosion-Resistant PVDF Housing: Withstood harsh wet well conditions, including flooding and H₂S gas.
RS485 Modbus Output: Integrated with the plant's SCADA system for remote monitoring and historical data logging.
📈 Implementation Results
30% Electricity Reduction: Annual pumping energy consumption dropped from 3.1 million kWh to 2.17 million kWh, saving ¥280,000 per year.
45% Fewer Pump Starts: Average daily pump starts decreased from 18 to 10, significantly reducing mechanical stress.
Zero Overflow Incidents: Reliable level measurement eliminated false readings and stuck-float failures.
Maintenance Savings: Float switch maintenance and replacement costs were eliminated, saving ¥50,000+ annually.
Extended Pump Life: Reduced cycling and optimized operation projected to extend pump service life by 3–5 years.
8‑Month ROI: The entire project paid for itself in less than a year through energy and maintenance savings.
💬 Customer Testimonial
“We knew our pump control was inefficient, but we were shocked by the 30% energy savings after installing the ultrasonic level meters. The precision is incredible – we can now maintain wet well levels within a 20cm band instead of the old 1.5meter swings. The pumps run smoother, start less often, and we haven't touched a single sensor in over a year. This is the smartest investment we've made in energy efficiency.”
