8200 Series
1-1/2” MNPT Top Mount Spiral Gauge for Marine and Water, Oil or Fuel Tanks
Application
The brass and stainless-steel construction of the 8200 Series spiral gauge makes it suitable for use in marine applications and in measuring levels of water, oil or fuel. They are also used in a variety of construction and maintenance vehicles such as road sweepers and water spray trucks.
General Information & Features
All 8200 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″ [914 mm] 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 8200 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 8280 spiral gauge is equipped with a standard top reading fractional dial or Rochester Remote Ready (R3D®) dial for telemetry application. The 8260 spiral gauge is supplied with an easy-to-read, side-view fractional dial.
The 8240 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. This gauge is not to be used for filling. All accuracy estimates are expressed as a percent of full scale.
