Mass Flowmeters & Controllers with Data Output

Brand: Vogtlin
Product Code: VEL00516

Accurate Measurement

The massflow devices offer high accuracy and a wide dynamic range with 2 different instrument versions “Standard” and “Hi-Performance”:

Accuracy up to ± 0.3% of full scale + ±0.5% of reading
Turndown ratio 1 : 100 (extended turndown ratio on request)


Analog & Digital

The mass flow meters and controllers of the red-y smart series make use of the latest MEMS technology and have a digital (Modbus RTU) and analog interface as standard.

Profibus interface is available as option (Profibus DP-V0/DP-V1).

A wide range of cable and power supply accessories is available


Operating Status Indication

The measurement and control instruments offer a built-in LED status indication

Safe & Fast Control

The red-y smart controller uses a tightly sealed control valve with a leak rate of less than 1×10-6mbar l/s He. Response times of approx. 150 msec for very fast set point control
