Vögtlin red-y compact series: mass flow meters
The Vögtlin red-y compact series offers compact and portable mass flow meters for gases, specially designed for applications where mobility, simplicity and flexibility are central. This series combines ease of use and accurate flow measurement in one handy unit, ideal for mobile measurements, service and test environments or OEM integration.
Key properties
The red-y compact series is developed for users who need mobile, flexible and reliable mass flow measurement without fixed installation. The series combines advanced MEMS technology with a user-friendly, modular setup.
Compact and portable design
Lightweight and easy to carry, ideal for mobile applications and service measurements.
Independent operation
The red-y compact mass flow meters run on an AA battery as standard, so they can be used completely independently. 24 VDC and micro-USB power options are also available for long-term or stationary applications.
Modular extensions
Thanks to the modular design, functionality can easily be extended with modules for power supply, alarm functions and analogue or pulse signals. Hierdoor is de meter flexibel inzetbaar in verschillende meetopstellingen.
USB interface
The red-y compact units can be powered via a micro-USB connection (DIN 62684). The USB interface also allows easy device updates and configuration.
MEMS sensor technology
The heart of the red-y compact series is a thermal MEMS sensor, with analogue-to-digital conversion taking place directly in the sensor. This ensures fast response, high accuracy and stable readings.
Integrated totaliser
In addition to the current flow value, the meter also shows the total gas consumption. This makes the red-y compact particularly suitable for consumption measurements and monitoring gas consumption.
One instrument for multiple gases
One red-y compact instrument can be used for up to three different gases or gas mixtures, offering flexibility for changing applications.
Wide choice of flow units
The user can choose from a large number of standardised flow units according to SI, imperial and US conventions. Both the current flow and the totalised flow can be set via the menu.
Password protection
To prevent unwanted changes, the red-y compact menu can be locked with a password.
Pressure and temperature compensated
Unlike variable area meters, these digital mass flow meters are insensitive to pressure and temperature fluctuations, ensuring reliable measurements under changing conditions.
3-year warranty
The red-y compact series comes with a 3-year warranty, underlining the quality and reliability of the instrument (excluding calibration, options and accessories).
