The 4-20 mA output signal of the VFI sensors, which is supplied by the two-wire transmitter, can be processed in all common industrial control systems and does not need to be calibrated when the sensor is connected. The output signal for flow and temperature measurement of the VFI+T sensors is a 0-10 V signal each and can be processed in all common industrial controls. When the sensor is connected, it does not need to be calibrated.
The sensor VFI requires a power supply of 12.5-30 VDC.
The sensor VFI+T requires a power supply of 16.6-30 VDC.

The output signal for flow and temperature measurement of the VFS sensors is a 0.5-3.5 V ratiometric signal for flow measurement and a 0.5-4.1 V ratiometric signal for temperature measurement and can be processed in all common industrial control systems. When connecting the sensor it does not need to be calibrated.
The VFS sensor requires a power supply of 5 VDC ± 5 %.
