TwinScan™ Instruments embody a new concept in twin engine analog instrumentation which sets the ultimate standard for easy readability in the least possible space. Each individual instrument contains port and starboard meters which reference to each other. TwinScan instruments reduce the panel space required by 50% leaving more room for other electronics. TwinScan Fuel Flowmeters and Tachometers are sold separately.

TwinScan Model Features
 

• Gallons Per Hour (GPH) models available with 0-16, 0-24, 0-32, 0-50, and 0-100 GPH scales.  Color styles include black dial/bezel, white dial/bezel, and white dial/chrome bezel.  Requires 1 SPST push button panel switch for resetting fuel totalizer reading.  Use recommended push button switch (MP39680) for this feature.
   
• Microprocessor electronics for high performance features like electronic dampening, linear dial scales, superior accuracy unaffected by ground voltage shifts.
   
• Patented, magnetically shielded, precision, miniature air-core meter movement with state-of-the-art engineering features.
   
• Corrosion free stainless steel bezel (black, white or polished) and molded acetal cases which fit standard 3-3/8" diameter holes.
   
• Reverse polarity and load dump protection exceeding SAE J1810 standards.
   
• Dial faces: Black on White, or White/Red on Black. U.S & Metric Scales.
   

The engines listed above have two fuel pumps. Because the engine's lift, or low pressure pump cycles on and off while filling the vapor separation module, the FloScan instrument GPH/LPH readings will constantly fluctuate between 0 GPH/LPH and approximately 25-50 GPH or 95-190 LPH depending on lift pump and engine size. Though the GPH/LPH readings are unusable, the FloScan instrument will accurately record total fuel consumption as displayed in the totalizer window.
