8600 Series
1-1/2” MNPT Top Mount Spiral Gauge for Hydraulic, Lubricating, Fuel-Oil, Gasoline and Diesel Tanks
Application
Models 8660 and 8680 are intended for stationary or mobile fuel tank applications containing middle distillates such as diesel and unless equipped with optional stainless steel support rods are not intended for use in fuels containing more than 10% ethanol or more than 30% bio-diesel. Models with optional stainless steel supports may also be used for fuels containing ethanol, bio-diesel and interstitial applications. These gauges are not intended for use in pressure vessels and are not recommended for off-road equipment.
General Information & Features
All 8600 Series spiral gauges have a 1 1⁄2″ MNPT tank connection and are suitable for tank pressures up to 25 PSIG [1.7 Bar] maximum. They are designed for top mounting only in tanks up to 36″ deep and some models are UL listed for flammable liquids. Lengths greater than 36.0″ up to max 49.0″ are available but excluded from warranty.
Rochester Sensors dials are magnetically driven and hermetically sealed. Thus, moisture and fuel vapor cannot reach inside of the gauge lens and attack the UV rated lens material. Also, all 8600 Series spiral gauges may be easily converted for remote telemetry monitoring by simply installing the Rochester Remote Ready Dial (R3D®) and plugin Hall Effect module sender (9704 or 9705).
The 8680 spiral gauge is equipped with a standard top reading fractional dial or R3D® dial for remote telemetry application. The 8660 spiral gauge is supplied with an easy to read, side-view fractional dial.
The 8640 spiral gauges incorporate a strong nickel-plated Neo magnet to drive the Resistive TwinSite® sender for electrical signal output (ohm) to a panel indicator or remote receiver while also providing a direct read, fractional reading.

General Specifications*
Mounting
Designed for top-mounting only.
Accuracy
Accuracy depends upon proper gauge sizing. Direct read dials +/-8%, TwinSite® dials +/-12%. Accuracy may be less depending upon tank shape. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. Device does not prevent overfill. All accuracy estimates are expressed as a percent of full scale.
Temperature
Standard operating range is -40°F to 158°F, -40°C to 70°C.
Humidity
Exposed portions should be painted for marine applications, less dial.
Shock
Shorter styles are suitable for some mobile, off-road applications.
Vibration
Shorter styles are suitable for some mobile, off-road applications.
Power
0.5 watts maximum for TwinSite® versions.
Tank Pressure
0 to 25 PSIG [0 – 1,7 Bar] maximum.
Approval
Direct indicating gauge. Available UL listed for flammable liquids. Some models UL recognized for marine service.
