While chlorine is one of the most commonly manufactured and used chemicals in the United States, it can also be a dangerous gas to work with. Chlorine gas has a variety of uses, including bleaching paper and cloth, treating waste, and as an ingredient in solvents, rubber, and pesticides. This gas is stored in pressurized cylinders and has to be monitored to prevent accidents and health and safety hazards.
Since the weight of chlorine gas is 2.5 times heavier than air, it stays low on the ground and rapidly spreads. This poses a risk to people who breathe it in, and it can have uncontrolled reactions with other chemicals such as ammonia or turpentine. As a result, combustibles like paper, oil or wood will easily ignite. Preventing leaks is key to chlorine gas safety, and knowing how much gas is left in a cylinder is an essential first step toward detecting a leak.

Arlyn’s Chlorine Cylinder Scales
Most cylinder capacity is checked by monitoring the pressure in the cylinder. However, this is not an effective way to determine the remaining contents of liquified gas cylinders because the pressure remains fairly constant until just before the gas runs out. This is why monitoring the weight is the most effective method for monitoring how much chemical gas remains in a tank,
In manufacturing, you are using extremely pure chemicals. Because each chemical has a unique specific gravity, the exact weight of the remaining gas is very easy to compute. A chlorine scale can subtract the standard weight of a cylinder and precisely calculate how much gas it contains. You will know exactly how much gas is left and can control how much is used in the process. This also lets you detect a potential leak if you are losing gas unexpectedly.
Arlyn has designed and manufactured scales specifically for the mentioned purpose while using industry-standard capacities of 60lbs to 300lbs. In order to provide a very thin platform, these scales use a special stainless steel load cell, and they can accommodate any combination of digital indicator or measurement output. These chlorine cylinder scales can accommodate cylinders, pails, gas cabinets and tanks within their rated capacity.
With a profile of only 1 3/8” in height, our Series 620G Gas Cylinder Scale is engineered to make loading and unloading easier. For environments that require an explosion-proof or intrinsically safe scale, Arlyn’s Intrinsically Safe Cylinder Scale is ideal. Measurement indicators include the 4-20mA, MKE5 indicator or the color touchscreen UPSCALE9 indicator. Scale capacities and resolution come in three different ranges: 60lbs x 0.02lb, 300lbs by 0.1lb and 400lbs by 0.1lb. The standard platform size is 9 ¼” by 9 ¼”; however, a larger platform size of 14” by 14” is also available.
Our Chlorine Ton Scales are a step above standard ton chlorine scales. Available in single and dual configurations, these scales offer better accuracy and corrosion resistance at an affordable price. While most other scales are constructed from welded steel, our Chlorine Ton Scales are made with stainless steel, giving them a longer lifespan. They also feature four heat-treated, abuse-resistant stainless steel load cells and can give a reading that is up to five times more accurate than a standard scale. For flexibility, Arlyn Chlorine Ton Scales have a variety of connectivity and output options, including a range of analog signals, Modbus RTU and even cloud monitoring. Load capacity is 5,000 pounds and the scale dimensions are 37″ x 20″.
In smaller water systems, chlorine gas is typically supplied in cylinders weighing 150 lbs with chlorine gas being sold “by the pound” while the cylinders are charged separately. Larger systems will use cylinders capable of 2000 lbs, known as “ton containers.” The weight refers to the chlorine being supplied, not the weight of the cylinder. Remember not to overload your scales by keeping these chlorine weight adjustments in mind. For reference:
- Full 150-pound cylinders will weigh approximately 235-290 pounds.
- Full ton containers will weigh approximately 3,300-3,650 pounds.
Although pure chlorine is used in manufacturing, it is seldom used for water treatment. The three most common chlorine-containing substances used in water treatment are chlorine gas, sodium hypochlorite, and calcium hypochlorite. When you chlorinate water, it affects the pH balance, which is a commonly overlooked fact for residential water treatment.
How To Handle Chlorine Gas Cylinders Safely
Chlorine gas appears as a greenish-yellow substance and smells like bleach. Exposure to chlorine is irritating at best and lethal at worst if it is breathed in or comes into contact with skin. If you manufacture other gases, keep chlorine gas away, as it is highly corrosive and will react violently if it comes into accidental contact. Remember to keep a carbon monoxide detector nearby as well, as this common substance will also produce combustible results. As mentioned, chlorine gas weighs more than air and will settle low to the ground, so ensure there is sufficient ventilation to disperse it. With proper training, workers can confidently and safely work around chlorine gas despite these hazards. The information provided here contains some basic tips and is not a suitable replacement for safety training. Please consult professionals for more in-depth information and proper training.
To start, it’s best to always have another person with you when handling chlorine cylinders and chlorine scales. If one person is suddenly incapacitated, the other can assist while calling for help as this can be a life or death situation. Each operator should have rubber gloves, protective outerwear, and goggles. Similar to a laboratory, a shower and eye washing station that produces warm water should also be readily available.
Safety Tips for Chlorine Cylinders and Scales
- Breathe shallow breaths around the containers until you can be sure a chlorine leak is not present.
- Do not lift a cylinder by its hood.
- Do not expose a cylinder to heat or direct sunlight.
- Do not drop a gas cylinder or knock it over.
- Remember to keep empty cylinders separate from full ones.
- Remember to secure empty and full chlorine cylinders with a cable or chain.
- Do not store chlorine with ammonia, diesel, gasoline, oil, or turpentine.
- Never move full ton containers onto scales designed to handle less than two tons.
- Do not store combustible or flammable materials near chlorine containers.
- Never spray water on a leaking container. It will make the leak worse.
Set Point Controller: How Can It Automate Manufacturing?
Automation of your manufacturing processes can not only save you time by eliminating human intervention, but it can also prevent costly mistakes caused by human error. For the health and safety of employees, a setpoint controller reduces accidents. Automating certain aspects of your processes is beneficial with chlorine cylinders, and the Arlyn setpoint controller can help.
The setpoint output controller is one output option on our chlorine cylinder scales. This output provides a simple batching and PLC type function that allows you to set up to 8 target weights at a time. These target weights will allow you to turn other equipment on or off, controlling them using solid state relays operated by the setpoint outputs. With the relays, you can control mixers, valves, feeders, solenoids, motors, or other devices within your manufacturing process.
The most common use for the setpoint controller is automating the filling and mixing operations in a manufacturing facility. By using the setup menu, you can input formulas to control how the output lines behave based on the weight applied to the scale platform.
You can even save different formulas in the scale memory and recall them as needed during the process. Automating your waste treatment process based on the amount of gas in the cylinder is an easy way to prevent accidents and make manufacturing run smoothly.
