The Portasteele® CALCULATOR is the perfect partner to any of Coltraco Ultrasonics’ liquid level detectors. It allows you to convert your measured liquid level to an agent weight, precisely and accurately. These readings can then be saved and exported for future reference and traceability.
Smart data recording
The Portasteele® CALCULATOR is designed for use with cylinders containing liquified agents, where there are distinct liquid and gas regions in the cylinder. However, there are a number of agents, such as CO2 and FE-13, which have what is known as their “critical point” within standard atmospheric temperatures, when stored at pressure. When a substance reaches its critical point, it ceases to exist as distinct layers of liquid and gas and becomes something known instead as a “supercritical fluid”. When this occurs, it is no longer possible to use the liquid level to monitor contents, as there will be no liquid level.
The Portasteele® CALCULATOR takes away the option to record data for substances that will likely be in this state. For CO2, for instance, this critical point occurs at 31°C, so if a user inputs a temperature in excess of this, the Portasteele® CALCULATOR will present an error and they will not be able to proceed and save this measurement.
