Next Generation Digital Massflow by Vögtlin

The 2015 generation of the digital mass flow meter red-y compact offers a new level of ease of use: compact design with battery power and backlit touch display for great flexibility.


The red-y compact series mass flow meters are characterized by powerful technology, intelligent functions and innovative design.

The 2015 generation instrument offers a new level of ease of use: compact design with battery power, backlit touch display and extended alarm function.


Touch Technology

The touch display offers intuitive navigation. The many variables that make the unit flexible are easily accessible. Automatic display adjustment thanks to position sensor.


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



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 (does not apply to calibration, options and accessories)
