Tariff Metering Apparatus TRIZ Cases
- In-Line Flow Meter Energy Harvesting for Pressure Regulation
A turbine-driven generator inside the flow path powers metrology hardware while electrical loading regulates pressure to protect measurement accuracy.
- Utility Meter HV Protection Module With MOV Fuse Isolation
A series resistor, MOV, and fuse let utility meters survive surge and overload events by isolating AC power before catastrophic failure.
- Load-Side Voltage Sensing to Block Hazardous Meter Reconnection
A meter circuit uses resistor networks, a reference divider, and pulse detection to stop remote reconnection when load-side voltage is present.
- Fire Hydrant Nozzle Cap Antenna for Real-Time Infrastructure Monitoring
A fire hydrant nozzle cap houses sensors and a protected antenna to enable real-time municipal infrastructure monitoring with fewer manual inspections.
- Gas Supply Remote Control with Authority and Operation Checks
Centralized server checks operation allowance and user authority before remotely controlling gas supply equipment, reducing manual workload.
- Consumption Meter Dismantling Using Push Pins for Low-Damage Recycling
Push pins penetrate the meter housing to separate the internal stack quickly, enabling recycling with minimal damage to electronics and batteries.
- Consumption Meter Housing Separation for Safe Recycling
Push pins penetrate the meter housing to separate the internal stack with minimal battery and PCB damage, enabling faster recycling.
