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: 2 in 1

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, Profinet RT and EtherCAT interfaces are available as option.

A wide range of cable and power supply accessories is available
