What is the impact of a different reference temperature?
The reference pressure in all units is designed for 1013.25 mbar. If you want to calculate the difference between 0 °C and 20 °C, e.g., the formula is as follows:
(flow at 0°C /273.15)*293.15
(Law of Boyle/Gay-Lussac)
Example: 100 ln/273.15*293.15 = 107,32 ls (=7.3%) This corresponds to a correction of 0.366 % per degree Celsius
How significant is the impact if the operating conditions change (pressure and temperature)?
The thermal mass flow meters and controllers directly measure the number of gas molecules (=mass), which flows past the sensor. The thermal flow measurement principle is therefore insensitive to changes in pressure and temperature. Vögtlin calibrates each unit on two temperatures and a temperature sensor in the gas stream compensates any minor temperature error due to temperature effects in the electronics. Due to this compensation there are almost no measurable temperature effects in the range of between 0…50 °C.
What reference conditions (pressure and temperature) are the devices specified for?
Unlike liquids, gases can be compressed. The volume changes when the temperature and/or the pressure change. When specifying a gas volume, the reference temperature and the reference pressure must thus also always be specified. The flow unit is than referred to as normalized (f.i. ln/min) or standardized flow (f.i. ls/min)
When we refer to “Normal” flow we in general use:
Temperature Tn = 273,15 K, corresponds to 0 °C
Pressure Pn = 1013,25 mbar abs
When we refer to “Standard” flow we in general use:
Temperature Tn = 293,15 K, corresponds to 20 °C
Pressure Pn = 1013,25 mbar abs
See also: http://en.wikipedia.org/wiki/standard conditions
Please note: Not everyone understands standard conditions in the same way. In the case of reference pressure, everyone agrees, but in the case of reference temperature, there are differences:
To avoid misunderstandings, the reference conditions are specified clearly in our correspondence.
On request, we also deliver the devices with another reference temperature.
How can the devices be controlled?
The measuring and regulating parameters of the red-y smart series and red-y industrial series can be read out or controlled in an analog, manual and digital manner.
Connect devices to the PC: What is needed?
Vögtlin offers a wide range of accessories, so that the devices can be operated directly via a PC with very little effort. In detail:
» Cable accessories for the red-y smart series
The free software get red-y offers a wide range of possibilities in context with the digital communication:
In addition, the following functions can optionally be unlocked:
Measuring range too large/small: Can the full scale of the device be adapted on site?
The mass flow meters and controllers of the red-y smart series and red-y industrial series have a very large dynamic range and can be converted to a certain extent on site.
A measuring device can be reprogrammed with the help of our service department by means of the get-red-y software. You will receive a password (valid for one day) for enabling this advanced function. Please contact our service department for more information.
Can the devices also be used in low pressure?
On principle, it is possible to utilize our thermal mass flow meters and controllers in the low pressure range. The sensor allows for an accurate flow measurement down to 100 mbar abs (we never verified lower pressures).
In the case of the flow regulators, a the low pressure is most of the time downstream of the control valve. The valves are vacuum-tight. The following must nonetheless be taken into consideration:
What information are required for selecting & sizing the mass flow meters & controllers?
Always provide a description of your application, why and how you want to use the units in your process.
At the very minimum we need the following information:
Does the mounting position need to be considered?
Basically, the red-y for gasflow mass flow meters and mass flow controllers can be installed in any position. At higher pressures and with dense gases such as krypton, a slight zero-point drift may occur. We therefore recommend using the devices horizontally wherever possible.
For the red-y smart pressure controllers with a small measuring range, the mounting position must be known. The dead weight of the pressure measuring cell can cause a zero point drift.
Does a massflow unit need a warm up time?
No, all red-y for gasflow devices are ready for immediate operation.
What is the impact of the moisture of the gas?
Moist gas of up to approx. 80 % rh has only a slight impact on the measuring accuracy. However, make sure that no condensation can take place in the measuring device. The condensation could settle on the sensor which could lead to inaccurate measurements. In the event that a measuring device has come into contact with condensation, it can for the most part be rinsed with a dry gas, such as N2. See also the remarks in the operating instructions.
Device parameters: What parameters can be changed on site?
The device parameters will be configured in the factory prior to delivery according to the data provided by you.
The following parameters can be set changed with the help of the get-red-y software:
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.
Is there a possibility for a remote maintenance in the event of malfunction?
Yes. In some cases it is convenient when we can access the client’s PC directly and solve issues online. Please contact us!
You can download the free software TeamViewer for remote support here.
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.
Where can I find information on the firmware and hardware version of a device?
Open get red-y and after your device has been recognized, select the menu “Overview”.
In the above example the device has FW version 6.1.09 and the hardware board version 6.0.03 (often documented as 6.0.3).

How do I adjust the communication settings (baud rate, parity, stop bits)?
Please keep in mind that the serial settings of your device and the get red-y software (or your PLC) must be set identical to allow communication between them.
Parity and stop bits settings, in addition to the baud rate configuration, are only available for smart6 device from the firmware v6.0.14, and supported by get red-y software from v5.7.0.6.
Settings on your device:
First, change the settings on your device with the help of the Register Tool from get red-y 5 software. For the release of this Register Tool function, you will have to ask a daily password from our service department.
1. Start get red-y and select the question mark (?)
2. Click on “password for one day” and enter the daily password received from the customer service
3. Click on “Password for one day” and enter the daily password you received from us
4. Click on the right mouse button within the device list to open the context menu for a specific device:
5. Select “Register Tool”
6. Within the Register addresses filed select “Baudrate” (=register 0x5200)
7. By selecting the “Read” button the default value “5” will appear.
Note: To change Baud rate, parity and Stop bits, you will have to select a unique value with 3 ditigs with the desired setting from the table below.
8. Now you will have to enter a 3 digits value, and select “Write”
As the changes are not anymore only done on the Baud rate, we will have to use 3 digits that will always operate a change on all three parameters.
The register now has three digits, which control the behaviour as given in the following table:
9. As the default communication settings under the get red-y software are now different from those on your device, the Error message “interface change” appears.
