Do I have to place a filter in the gas line to the flow meter/controller?
If you use gas from a bottle which is clean and dry, there is, in general no need for a filter.
However, there is a risk during start-up of the devices, because dirt particles could be present in the line. It is recommended to install a bypass system, so that the line can be rinsed or can be exposed in response to possible repairs.
In the event that ambient or compressed air is used, the installation of a moisture and dust filter is strongly recommended.
Troubleshooting: Is there a checklist?
Within the troubleshooting pages in the operating instructions, we have summarised error patterns, possible causes and possible measures. If you do not recognise your error pattern or the suggested action is unsuccessful, please contact your Sales Ppartner. If you return the appliance, please refer to the ‘Returns’ section in the operating instructions.
How can the devices be cleaned?
Depending on the type of contamination, the devices can be cleaned on site. You can find more information on this topic in the operating instructions.
Periodic calibration: How often do the devices need to be calibrated?
In principle, the user himself determines the calibrating interval. People often use one per year or in case of very clean gas, one per 2 years. The following questions/points can be helpful:
We suggest the following calibration interval:
1. First inspection after one year
2. After several calibrations have been made in succession, the deviation of calibration to calibration must be evaluated. Based on these data, a decision can be made to adapt the calibrating intervals.
The following influences can lead to an increased deviation:
1. No stable flow, caused by pulsating pumps, e.g.
2. The gas condenses or carries along liquid or dusty particles (applications with ambient air are particularly susceptible to contaminations. A filter needs to be provided here).
3. The effective pressure deviates considerably from the calibrated pressure (+/- 0,2%/bar).
4. The gas/gas mixture is not consistent with the calibrated gas.
5. The aging of electronic components can cause changes, sometimes even improvements. Electrical changes appear as a result of aging or gradual burning of components, which impact the quality of the output signal.
