Independent Operation

The red-y compact mass flow meters are powered with a standard AA battery.
Optional 24 Vdc and Micro-USB power supply available 

USB Enabled

The red-y compact measurements instruments can be powered with any common Micro-USB power supply (DIN62684). Device updates can be performed using the USB interface  

High Accuracy & Dynamics

The devices offer high accuracy and a wide dynamic range:
Accuracy up to ± 1% of full scale
(depending on application/measuring range)
Turndown ratio 1 : 100

Extended Alarm Functions

The red-y compact 2 series provides 3 configurable alarms. The following triggers are available:
Low alarm, high alarm, window alarm and totalizer alarm
The alarms can be configured with different parameters:
Normally open, normally closed, hysteresis, auto/manual/remote reset, delay and alarm duration

MEMS Sensor

The MEMS semiconductor chip is the centerpiece of the thermal mass flow meter.
Analog-digital conversion takes place in the sensor

Totalizer

In addition to the actual flow, the total consumption is displayed. Ideal for gas consumption measurements

1 Device – Multiple Gases

One red-y compact measuring device can be used for up to 3 different gases or gas mixtures

Wide Choice of Flow Units

Choose between a large number of standardized and normalized flow units of the Imperial, US customary and SI measuring systems (with user adjustable reference conditions).
The units are selectable from the integrated menu both for the actual flow and the totalized flow

Password Protection

To avoid unauthorised change of settings, the menu of the new red-y compact can be locked with a password

High-precision Valve

In the red-y compact regulator / all-in versions with manual valves, high-precision needle valves are used. These valves allow fine adjustment of the flow rate

Pressure & Temperature compensated

In contrast to variable area flow meters, the digital mass flow devices are insensitive to pressure and temperature changes

3-Year Warranty

High-quality components ensure long and trouble-free operation

Firmware Update 3.0.6 for red-y compact 2 series

Firmware Update 3.0.6 for compact 2 with advanced swipe control

For the digital mass flow meters of the red-y compact series (device generation 2) a new firmware with new advanced features is available. The firmware version 3.0.6 is available free of charge and applicable to all compact 2 devices (SN > 300000).

New features & improvements:

Swipe Control

Customers now can choose to operate the device with a gesture control (swipe control) in addition to the previous mode of operation. After the firmware update, the touch screen must be recalibrated once. The calibration of the touch screen starts automatically after the firmware update. The swipe control feature can then be activated via the menu. See operating instructions chapter 4.12.2.6 and 4.12.2.7

Energy optimization in Performance mode

The device can now be operated in continuous mode for almost twice as long (approx. 5 days) with a high sampling rate of 40ms.

User-defined storage interval for the totalizer

The user can now define the interval at which the totalizer value is written to the non-volatile memory (EEPROM). By default this is every 10 minutes (600 sec.). The user can adjust this interval in steps of seconds.
Note: A faster storage interval reduces the lifetime of the EEPROM. Changing the storage interval voids the warranty on the EEPROM. See operating instructions chapter 4.11.3.

Extended resetting options for the totalizer

The alarm module offers now the possibility to reset the totalizer also via an external source (e.g. push button). All the options are described in detail in chapter 4.11.3 in the operating instructions.


Important Note:
After the firmware update, the touch screen must be recalibrated once. The calibration of the touch screen starts automatically after the firmware update. The swipe control feature can then be activated via the menu. See operating instructions chapter 4.12.2.6 and 4.12.2.7

For detailed information on updated features check the release note provided with the firmware update.
With the new firmware we also release updated operating instructions version A2-2. Hereby all technical details from previous manuals are no longer valid.

red-y compact 2 series Service Tool with Firmware Update 3.0.6

Previous versions of the firmware are available here.

Update notes: The installer and firmware are packed into the Vögtlin Service Tool package that is simple and reliable to use (no software installation required). The update takes place through the USB cable supplied with the unit upon purchase*. Please read the manual supplied with the Service Tool package. Detailed update instructions are available in the new operating instructions of the red-y compact 2 series.

*or most generic charging cables for smartphones (USB micro-B) can be used
