Taylor RoadMaster Liquid-Level Gauges

ApplicationThe RM Series Road Master gauges were de signed to with stand the vi bra tion and shock in her ent in mo bile service. Their ser vice life in over-the-road and off-road transports, car ry ing liquids rang ing from LP-gas to crude oil, is un sur passed. These gaug es al low a con tin u ous read ing be tween 5% and 95% of tank contents.

General In for ma tion & Fea tures*The RM Series Road Master gaug es are to be installed in the side or end of mobile tanks at the cen ter line. They are equipped with a spring controlled shock ab sorb er on the float arm which sub-stan tial ly reduces the stress that quick ly de stroys con ven tion al gauges. Angle mounting gaug es are also available.

The standard model in cor po rates a 4” [100 mm] dial with an available 8” [200 mm] dial. When nec es-sary, the dials are easily re place able.

Magnetic Liquid-LevelGaug es For NH3 WithChem i cal Additives

ApplicationThis magnetic liquid-level gauge is especially de signed for use in NH3 with chemical ad di tives. Gauges are available for all tanks and any mounting position.

General In for ma tion & FeaturesThese gauges are built to the highest standards of man u fac tur ing and thor ough ly field tested. The mag net ic con struc tion permits the com plete seal ing-off of the inside liquid from the outside gauge head and dial. This eliminates many hazards and permits dial re place ment quick ly with out loss of liq-uid by simply removing two screws. All dial cap sules are easy-to-read, her met i cal ly sealed, vac u um test ed and elim i nate fogging. Dial pointers are silicone dampened. These gauges are UL listed for NH3 or LPG ser vice.

Taylor‘s rugged gear drive is stan dard with shrouded stainless steel bev eled gears es pe cial ly de signed to shed and work out any loose par ti cles which might affect action. From the her met i cal ly-sealed dial to the one-piece head, body and fusion welded float, each gauge is es pe cial ly suit able for ad di tive ap pli ca tion and will pro vide long trou ble-free ser vice in even the most severe use. Mount ing may be ac com plished in all de sired po si tions where cir cum stanc es per mit.

The Eliminator™ Rotogauge Replacement

For LP Gas & NH3 Service

ApplicationThe Eliminator™ direct-reading float gauge is a direct re place-ment for 1” NPT rotary-type dip-tube gauges in LP and NH3 storage tanks. These gauges are de signed for larger tanks up to 84” [2134mm] in diameter. The Elim i na tor™ is not intended for use in filling tanks - its use is re strict ed to tanks with fixed liquid level gauges, used to determine when the maximum fill level has been reached. The eliminator can be used in mobile ap pli ca tions up to 60” [1828mm] in diameter.†

How To Do The Conversion1. After the storage tank has been evacuated, remove the

ro ta ry gauge from the 1” NPT open ing at the centerline of the head. Clean and re-tap the fe male threads.

2. Remove the two screws from the bezel. Put the bezel, screws and dial chamber aside for the moment. Remove the four mount ing screws holding the gauge head to the adapt er.

3. Insert the lower portion of the replacement gauge, including the float bulb, float arm, gear hous ing and counterbalance, into the tank open ing.

4. Apply three wraps of 1⁄2” [12mm] wide Te flon tape, or other suitable thread seal ant, to the 1” NPT threads on the steel adapt er through which the gauge sup-port pass es.

5. Screw the adapter into the tank open ing to achieve a leak-tight joint, and align the gauge mounting holes in the hor i zon tal plane.

6. Using the gasket and four mounting screws supplied, attach the gauge to the adapter fingertight. Be sure the gauge is right side up, the bracket tab for lo cat-ing dial cham ber should be on the right. Torque the mounting screws even ly to 140/150 lb.in., [16,4Nm]

us ing a cross pat tern.

7. Reattach the 4” dial chamber and be zel to the Se nior™ gauge head brackets using the two screws supplied.

8. If you end up with the dial cham ber up side down, you cannot solve the problem by ro tat ing the brack et. You must ro tate the en tire gauge 180°.

Junior and Senior Liquid-Level GaugesFor LP Gas Service

Application Junior gauges are supplied standard with Buna-N gas-ket and four zinc-plated steel mounting screws (1⁄4” — 28 x 7⁄8”) for attachment to a gauge adapter with 2.03” [51, 5] diameter bolt circle.

Junior gauges used on above or below ground ASME storage tanks are equipped with direct reading per cent-age dials. Junior Gauge Mod els used on ASME motor fuel tanks are equipped with direct-read ing frac tion al dials.

All Senior gauges come equipped with Buna-N gas kets and four zinc plated steel mount ing screws, (5⁄16” — 24 x 7⁄8”), for at tach ment to a gauge adapter with 2.5” [63, 5] diameter bolt circle. Senior gauges used on above ground ASME storage tanks are equipped with direct-reading per cent age di als.

Senior gauges with stainless steel heads may be used on above ground hor i zon tal or ver ti cal ASME stor age tanks over 3500 [13250 liters] gallon capacity and are equipped with cap screws, teflon-filled, stainless steel gas kets, stronger magnets and direct-reading 4” diam-eter per cent age dials. Tank draw ings must be fur nished for all ver ti cal tanks so we can recommend com put er gen er at ed gauge adapter place ment to cor re spond with an as sort ment of standard dials and dial sets calibrated for vertical tanks.

The “One” Gauge™

Adjustable Liquid-Level Gauge

ApplicationThe “One” Gauge™ is a magnetically-cou pled liq uid-lev el gauge that ad justs in length and ac cepts a va ri ety of float stem lengths. This feature makes it easy to quickly and economically replace non-func tion al gaug es in the field for a large variety of tank siz es. They are UL listed.

General In for ma tion & Fea turesThis gauge features a range of ad just able stems which, when mated with an ap pro pri ate-length float as sem bly, enables LP Gas dealers to easily re place the liq uid-lev el gauge in vir tu al ly all LP Gas tanks used for do mes-tic storage or mobile applications.

The design utilizes a D-shaped alu mi num centershaft which is housed in telescoping alu mi num sup port tubes. An alu mi num lock nut com press es an aluminum locking sleeve to se cure the tubes at the required stem length. All oth er com po nents are of the same materials as stan dard Rochester LP Gas gauges.

The proper float assembly is at tached to the gear hous ing on the ad just-able stem per in struc tions shown on the re verse side of this data sheet.

1. Basic dimensions of the American National Standard Taper Pipe Thread are given in inches to 4 or 5 decimal places. While this implies a greater degree of precision than is ordinarily attained, these di men sions are the basis of the gauge dimensions and are so expressed for the purpose of eliminating errors in com pu ta tions.

2. Also length of thin ring gauge and length from gauging notch to small end of plug gauge.3. Also pitch diameter at gauging notch (handtight plane).4. Also length of plug gauge.5. The length L5 from the end of the pipe determines the plane beyond which the thread form is incomplete

at the crest. The next 2 threads are complete at the root. At this plane, the cone formed by the crests of the thread intersects the cyl in der forming the external surface of the pipe. L5=L2-2p

6. Given as information for use in selecting tap drills.7. Military Specification MIL-P-7105 gives the wrench makeup as three threads for sizes 3 & smaller.8. Reference dimension.
