When Ordering Specify:

1. Liquid to be gauged and specific gravity.
2. Inside diameter of tank heads: ellipsoidal, semi-ellipsoidal or hemispherical.
3. Complete model number desired from price list 6300 (example M6342-11).
4. Prefix letters for available options from price list 6300.
5. If a dial other than standard are required, furnish drawing and/or details.
6. Furnish tank drawings whenever ordering gauges for angle-mounting or for installation in vertical tanks.
7. If tank mounting flange is required, order separately from chart.

*Materials and specifications are subject to change without notice. Pressure ratings subject to change due to temperature and other environmental considerations.

CAUTION: For LP Gas or NH3 applications requiring 2″ NPT connections, specify Y6300 Series Magnetel gauges which includes 0022-00525 schedule 80 adapter assembled to gauge. NOTE: Y6300 Series gauges will fit through 2″ pipe coupling but will NOT fit through 2″ pipe nipple.

Accuracy
Accuracy of Magnetel gauge dial indication estimated ±10% as a percent of full scale. Accuracy depends upon proper gauge sizing. Accuracy may be less for some tank shapes and sizes. 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.

Caution: This gauge is not a substitute for an automatic overfill prevention device, which may be required for filling. This gauge is not to be used as an unattended means of determining tank overfilling. This document does not provide instructions for tank filling. Periodic annual operability checks may be required which are necessary to detect gauge malfunctions and/or inaccurate gauge readings. Gauge accuracy depends upon proper gauge sizing and installation. Release of tank contents as well as damage and safety hazard may result if tank is overfilled. Fuel exhaustion may occur if tank contents are less than indicated.

Precaution for LPG and NH3: Accurate measurement of Liquefied-Petroleum Gas (LPG), or Anhydrous Ammonia (NH3), requires converting a volume measured at an observed temperature to the volume at a standard base temperature of 60°F. LP Gas is usually a mixture of propane, butane and possibly other gases, so the conversion factor is usually determined from a chart when the specific gravity of the LP Gas is at 60°F is known.
