Part 2: How Wireless Magnetic Propane Sensors Work
Measurement Technology
Most wireless magnetic sensors use ultrasonic technology:
Step-by-Step Process:
Magnetic Attachment
Strong rare-earth magnet (neodymium) secures sensor to steel tank
No drilling, screws, or adhesive required
Sensor stays firmly attached in all weather conditions
Ultrasonic Measurement
Sensor emits high-frequency sound waves
Waves travel through tank wall into propane liquid
Waves bounce off liquid surface and return to sensor
Sensor calculates liquid height based on travel time
Data Processing
Onboard processor converts measurement to percentage
Calculation accounts for tank size (entered during setup)
Accuracy: ±2-3%
Wireless Transmission
Data sent to smartphone via Bluetooth, WiFi, or Cellular
Transmission frequency: Every 1-60 minutes (varies by product)
Encrypted for security
App Display
Real-time level shown as percentage and gallons
Usage history and trends
Days remaining prediction (based on usage patterns)
Low-level alerts at custom thresholds
