Liquefied gas cylinders are used in numerous industrial processes. The semiconductor industry is one typical application. Monitoring the pressure in the cylinder is not an effective way to determine the amount of contents because the pressure will stay near maximum until just before the last of the gas is used. Monitoring the weight is the most effective way to determine the amount remaining. Arlyn’s Cylinder Scales are specifically designed for this purpose with industry standard capacities of 60 lb and 300 lbs. All our Cylinder Scale models use a special stainless steel load cell to provide a very thin platform with a size of 9.25” x 9.25”. A platform measuring 14”x 14” (Standard Aluminum only) is also available for our Liquid Tank scales. Weight can be read on a digital indicator, or output using 4-20mA, 0-5V, 1-5V or any combination.

Very Thin Profile

Loading and unloading heavy cylinders can be a difficult process. We have engineered our scales to ensure a low profile and to make this process easier. Our Cylinder Scale’s profile is only 1 3/8” high!


Our Cylinder Scales are also available in All Stainless Construction (including pan, frame, load cells and legs). The scale can be upgraded to 12" x 12" or 14" x 14" platform. Other sizes as small as 4" x 4" also available. For custom sizes, please call our factory.

Very Versatile

Available with different outputs, including 4-20mA, 0-5V, 1-5V or with a full functioned indicator that can be enhanced by a variety of computer output formats, including RS-232, Wi-Fi, Ethernet and USB

High Precision

Weights can be read as closely as 0.02 lb. For even better accuracy, see Arlyn’s Ultra Precision Scales.

AxChange Cloud Monitoring

Monitor and Track your industrial scales on the cloud, anywhere on any device using the new AxChange Cloud Monitoring and Weight Tracking system. Limited free beta accounts available.

Intrinsically Safe Versions Available

For hazardous or classified environments, see Arlyn's Intrinsically Safe ArlynGuard C Series Cylinder Scales equipped with FM Approved display indicator and load cell sensors.

Other Configurations

  • 2-Wire or 3-Wire 4-20mA (no display): These scales can also be configured for applications that do not require a Digital Display Indicator. This is suitable if your application requires this scale with a 2- or 3-wire 4-20mA or 0-5V interface without a display. Use the "Configure & Buy" option above to select your interface.
  • Load Cell Kits (without platform): We also provide load cell kits with capacities as stated for these types of scales. The kits include the heavy duty stainless steel load cells, legs, and other hardware. The kit can also include the scale display if requested.
For these and other configurations, please contact us or call us at (800) 645-4301 and we will be happy to help.
