Vogtlin Red-y Compact 2 Series Digital Mass Flow Meters and Regulators

The Vogtlin red-y compact 2 series mass flow meters are characterized by powerful technology, intelligent functions and innovative design.This latest generation offers a new level of ease of use: compact design with battery power and touch display for great flexibility and extended alarm function.


Touch Interface

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

Independent Operation

The flow meters are powered with a standard AA battery or Micro-USB power supply. Optional 24 Vdc power supply available.

Modular Extensions

The instruments can be extended and retrofitted with different modules: battery module, power module and alarm module.

High Accuracy & Dynamics

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


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

1 Device – Multiple Gases

One measuring device can be used for up to 3 different gases or gas mixtures.

Password Protection

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