Manual regulation with emergency oxygenation
A manual regulation system controls or regulates the addition of oxygen without automatic or electronic control.
Manual regulation with emergency oxygenation
Our manual regulation systems use a rotameter – a type of flow meter that measures volumetric flow rate – meaning that the operator adjusts the volume of flow by physically adjusting the valves based on the rotameter’s measurements.
Introduction
When should I choose manual regulation?
Manual regulation is relatively simple and ideal where precise regulation is not critical or where automation is not practical.
How does manual regulation work?
The rotameter sits in the gas flow and has a float inside a vertical conical tube. When liquid or gas flows upwards, it pushes the float up, which stabilises at a point where the force of the flow is balanced by gravity. The position of the float in the pipe indicates the flow rate, which can be read directly.
The operator observes the rotameter and manually adjusts valves to achieve the desired volume of flow. This means that the system requires constant supervision and control by the operator, who must monitor the measurement and adjust if necessary.
Manual regulation can be supplied with an automatic emergency system that switches to an alternative oxygen source in the event of an issue such as a power cut.
