Level Control TRIZ Cases
- Battery-Powered Fuel Shutoff Valve for Automatic Tank Level Control
A battery-powered sensor and motorized valve automate tank shutoff to prevent refueling errors and unsafe fuel delivery in oilfield equipment.
- Cooling Tower Blowdown Control Using Flow Threshold Feedback
Flow-threshold sensing permits cooling tower blowdown only when real discharge is present, preventing valve faults from disrupting water chemistry.
- Hydrogen Peroxide Reservoir Float Sensing for Precise Flow Measurement
A laser sensor tracks a float through a transparent cover to improve low-flow hydrogen peroxide measurement while preserving reservoir sterility.
- Adjustable Spillover Drain Assembly With Debris-Straining Cage
A sliding spillover tube and strainer cage let fluid tanks switch overflow levels without removal while blocking debris that causes clogs.
- Electrochemical Water Treatment Electrode Packs for Low-Scaling Flow
Modular electrode packs and funnel-shaped adapters disinfect water without chemicals while raising flow velocity to reduce electrode scaling.
- Pressure Sewer Pump Control With Remote Overflow Monitoring
Remote fluid-level monitoring and server-linked pump control help detect sewer pump faults early and prevent reservoir overflow and leakage.
- Stacked Submersible Pumps With Autonomous Level-Based Speed Control
Independent level-sensing pumps in a vertical stack adjust speed autonomously and enable backflow flushing to handle variable fluid levels.
- Perforated Subirrigation Pipe Layout to Prevent Drainage Blockage
Flow guide baffles and an inner irrigation pipe split water paths to prevent clogging, improve root watering, and reduce waste.
- Float-Based Tank Fill Control for Overfill and Overpressure
A float level sensor and control unit stop or adjust tank filling at a set maximum level to prevent overfill, overpressure, spills, and damage.
- Blow Case Outlet Layout for Debris Flushing and Valve Access
Top-mounted clapper and pneumatic valves let a blow case flush debris through the outlet while enabling above-ground maintenance.
