The Fly Henry Water/Oil Sensor for the FLY Meter is a specialized temperature probe used for real-time monitoring of liquid-cooled engines or engine oil. Unlike general-purpose sensors, this version is specifically designed to interface with the FLY Meter’s measurement module.
Core Functionality
In the FLY Meter system, this sensor is distinct from the CHT/EGT thermocouples. It is an NTC (Negative Temperature Coefficient) thermistor designed for lower temperature ranges:
Measurement Range: 0°C to 125°C (standard) or up to 300°C for specific high-heat models.
Dual Use: The same sensor is used for both water and oil; you simply configure the FLY Meter display to show the appropriate label.
Technical Specifications
Threads: Available in three metric sizes to fit engine blocks, water pump housings, or hose adapters:
M6 x 1.0 mm
M8 x 1.0 mm
M10 x 1.0 mm
Cable Options:
New Model: Features a 50 cm black insulated lead with a specific connector for the Fly Henry Measurement Module.
Construction: Brass or stainless steel body for high thermal conductivity and corrosion resistance.
FLY Meter Specific Configuration
Within the FLY Meter 2024/2025 menu settings, this sensor provides specific features that standard gauges lack:
Preset Profiles: The instrument includes preset curves for "New Fly Henry" and "Old Fly Henry" sensors so you don't have to manually calibrate resistance values.
Custom Calibration: If you use a non-Fly Henry sensor, the FLY Meter allows you to input custom resistance values to ensure the temperature reading is accurate.
Alarms: You can set a dedicated "Water/Oil Temperature Alarm" (e.g., at 110°C). When triggered, the FLY Meter display will flash and highlight the temperature value to grab your attention.
