Frequently Asked Questions (FAQs)
All Questions
Massflow
VA-Meters
Are there conversion factors for changing operation conditions?
Can the devices also be used in low pressure?
Create a stable flow at fluctuating back pressures
Which measuring scales are available?
Do I have to place a filter in the gas line to the flow meter/controller?
Does a massflow unit need a warm up time?
Does the installation position need to be considered?
How can the devices be cleaned?
How can the devices be controlled (red-y smart series)?
How does a variable area flow meter work?
How large is the impact, when the operating conditions change (pressure and temperature)?
Is there a possibility for a remote maintenance in the event of malfunction?
Periodic calibration: How often do the devices need to be calibrated?
The measuring range is too large/too small. Can the final value of the device be adapted on site?
Valve at the inlet or outlet: What are the bases for the decision?
What conditions (pressure and temperature) are the devices designed for?
What device parameters can be changed on site (red-y smart series)?
What information do we need for selecting and sizing the mass flow meters and controllers?
What is required to let the smart series communicate to a PC?
What is the impact of a different reference temperature?
What is the impact of the moisture of the gas?
What process information is required for the design of the measuring device?
