Sometimes standard scales are not equipped with the necessary elements to make them resistant to corrosive materials. Certain industrial environments make it difficult to use these scales to weigh cylinders and containers of chemicals and other corrosives. Aggressive acids and caustics present in these environments affect the materials used in standard scales, which ultimately render the scale defective and inaccurate.
Water and wastewater treatment plants, chemical manufacturing plants, electro-plating environments, the semiconductor industry, and the fertilizer and agricultural manufacturing industries, among many others, require scales far more rugged and durable than the industry standard with capacities able to withstand cylinders that can easily weigh a ton and whose construction provides the utmost in corrosion resistance.
Arlyn’s Corrosion Resistant Scales
Our corrosion resistant scales are ideal for weighing cylinders and other containers of corrosive materials. Liquefied gases such as chlorine, sulfur dioxide, ammonia, hydrogen chloride and carbon and chemicals like fluoride, sodium hypochlorite, sodium hydroxide, phosphate, alum, and many other caustics may be weighed and monitored without fear that their corrosive nature will damage the scale.
Low Profile Platform and Ramps
Because cylinders and other containers are usually placed on the scale using wheeled carts, dollies, or by directly rolling the drum onto the platform, these scales often require ramps to accommodate this method of loading and unloading.
However, standard platform heights have made it so that scales and their ramps take up much of the warehouse or factory floor. Traditionally, the on and off ramps had to be as large as, or larger than the scale platform or higher to accommodate the height. We have also eliminated the side rails, making the platform much more accessible and loading and unloading much easier and faster.
Our scales are constructed with a low profile that is less than two inches high. This way, if you choose to order your scale with the optional on and off ramps, the entire system will take up much less space, providing you with more room for other operational necessities.
Three Part Galvanized Polyamine Epoxy Coating
Our unique, three-part galvanized epoxy coating is applied over our stainless steel construction allowing for rugged use and excellent chemical resistance to both organic and inorganic caustics. Even strong acids, solvents, petrochemicals, and alcohol will not damage or break through this coating.
Our method of application ensures that the polyamine coating adheres to the scale, not only protecting the platform from corrosive elements but, due to the garnet particles embedded in the mixture, also makes the surface scratch and skid resistant.
This scratch resistant quality is extremely important because it is through such scratches that leaking chemicals find their way into and corrode the underlying structure of the scale, ultimately rendering it inaccurate. Repairs quickly become costly and eventually impossible, making replacement the only viable option. This, too, becomes costly.
While many other coatings become worn and ineffective due to exposure to sunlight, the most that will happen to this coating even after years of exposure is some discoloration and loss of surface gloss. While there may eventually be some chalking and powdering of the surface, this will not affect the anticorrosion properties of the scale.
Load Cell Protection
While the polyamine coating is effective at protecting the surface of the scale, it will not protect the load cells. This is because its application to a load cell would affect the cellÕs ability to provide accurate readings. This is why we coat them instead in a compliant RTV material. Internal positioning within the scale will protect them from exposure to any corrosive materials that may be spilled or otherwise introduced to the environment. While the fumes of these chemicals can also be corrosive, we coat our load cells not with polyamine, but with a thin layer of compliant RTV material.
The Importance of Monitoring Chemical Weights
Sometimes monitoring chemical weights becomes a matter of the public health. When it comes to water and wastewater treatment plants, a variety of chemicals are used to make the water potable for municipal districts. They are also used to treat sewage and other wastewater. Chlorine is one of the most common and important chemicals used during this process.
Usually stored in liquid form in a ton cylinder, chlorine can also be stored as a liquefied gas. Monitoring the cylinders housing either form of this chemical is incredibly important to maintaining the public health. If a cylinder is not replaced or refilled before it is depleted, the proper amount of purifying chemicals will not be added to the water, posing serious health issues.
No matter what industry you work in, monitoring the weight of chemical filled cylinders is necessary not only for accuracy, but also for the safety of everyone involved in the process, from manufacture to purchase.
We make it easy to monitor chemical weights with our digital indicator. Whether you need to fill drums, tanks, or cylinders when they are empty, or empty them when they are full, we offer custom equipment that allows you to monitor and manipulate the entire process.
Alarms may also be set to alert operators when cylinders reach their maximum or lowest capacity. These alarms may be monitored locally, or reported electronically using a USB or RS-485 to computer connection. The scale can also use Ethernet output to connect to a local area connection or the Internet, depending on your needs.
Our connectivity options allow for remote control of the scale and any accompanying filling equipment, making it possible to turn on or shut off a variety of different devices. Depending on what option you choose, this can be done from anywhere in the world.
