6200 Series

Magnetic Liquid-Level Gauges for LP Gas Service

Application

Junior gauges are supplied standard with 0015-00007 Buna-N gasket and four 0040-00414 zinc-plated steel mounting bolts (1⁄4" — 28 x 7⁄8") for attachment to a gauge adapter with 2.03" [51,5] diameter bolt circle (see installation instructions MS-501/502).

Models 6281 and 6284 Junior gauges used on above ground ASME storage tanks are equipped with R3D® Remote Ready 5909S02733 percentage dials. Model 6281 Jun­ior gauges used on below ground ASME storage tanks are equipped with R3D® Remote Ready 5909S02799 per­cent­age dials. Mod­els 6241 and 6244 Junior gauges used on ASME motor fuel tanks come with the option of direct read, TwinSite®, or Hall Effect dials.

All gauges in the 6240 series and B6240 series incorporate a stronger magnet necessary to drive remote reading TwinSite® senders in motor fuel applications.

All Senior gauges except models 6290 and 6293 come equipped with 0015-00004
Buna-N gaskets and four 0040-00415 zinc plated steel mounting bolts,
(5⁄16" — 24 x 7⁄8"), for attachment to a gauge adapter with 2.5" [63,5] diameter bolt circle (see installation instructions MS-501/502). Model 6280 and 6283 Senior gauges used on above ground ASME storage tanks are equipped with direct-reading 5001S00001 percentage dials.

Models 6290 and 6293 Senior gauges with stainless steel heads may be used on above ground horizontal or vertical ASME storage tanks over 3500 [13250 liters] gallon capacity and are equipped with cap bolts, Teflon-filled, stainless steel gaskets, stronger magnets and direct-reading 4" diameter percentage dials. Tank drawings must be furnished for all vertical tanks so we can recommend computer generated gauge adapter placement to correspond with an assortment of standard dials and dial sets calibrated for vertical tanks.

General Specifications*

Temperature

Standard range is -40°F to 176°F, -40°C to 80°C.

Accuracy

Accuracy depends upon proper gauge sizing. Junior and Senior dials ±5%, 4” dials ± 4%, TwinSite® dials ±8%. Hall dial output ±4% of visual reading. 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. Accuracy may be less due to variations in liquid temperature. This gauge is not to be used for filling. All accuracy estimates are expressed as percent of full scale.

Humidity

For high humidity below ground or under chassis applications, brass, stainless steel or painted aluminum heads are recommended.

Shock & Vibration

Suitable for mobile service applications.

Power

0.5 watts maximum dissipation for TwinSite® versions.

Work Pressure

375 psi. [25,5 Bar].

Approvals

Gauges are UL listed for LP Gas service applications.

 

When Ordering Specify:

1. Gauge head size, Junior or Senior, or model #.

2. Tank diameter shown on nameplate.

3. Mounting location (top, side, end or angle).

4. If the gauge is angle mounted, state angle.

5. If the gauge is end mounted, state the shape of the tank head (hemispherical or semi-ellipsoidal).

6. Specify the “H” dimension (the distance in inches from the surface of the tank to the gasket surface on the riser).

To order a replacement gauge, simply furnish the information stamped on one of the flat sections on the side of the gauge head as shown in the example below.

 

Note: For installation instructions see MS-501/502 (mounting standard).
