The 8600 Series Senior spiral gauges are designed for use in measuring liquid levels in hydraulic, lubricating or fuel-oil storage tanks, and gasoline and diesel fuel levels in stationary, standby and mobile generators. The 8600 Series is not recommended for off-road equipment.
The 8640 spiral gauge incorporates a strong nickel-plated Neo magnet capable of driving a TwinSite® sender which provides a direct, fractional reading and also sends an electrical signal to a remote receiver.
All 8600 Series spiral gauges have a 1 1/2 in. MNPT tank connection and are suitable for tank pressures up to 25 psig maximum. They are designed for top mounting in tanks.
