Flow meters perform different tasks in conditioning systems for gas analysis.
Flow meters perform different tasks in conditioning systems for gas analysis. The typically quite complex applications require the use of particularly corrosion-resistant materials and high operating reliability.
In addition to purely monitoring and regulating the flow, flow meters can also be used to monitor the contamination level of the filters conditioning line upstream from the flow meter.
Electric limit switches can be mounted to the measuring tube for this purpose. These connect to the control system via suitable switch amplifiers.
Types with built-in needle valve further allow for setting a specific flow rate.
