"Frequency" option
Flow-proportional frequency output with 1:1 on/off ratio
An output frequency is output that is proportional to the value of a process variable, such
as volume flow, mass flow, corrected volume flow, flow velocity, conductivity, corrected
conductivity, temperature or electronic temperature.
Example
• Flow rate approx. 100 g/s
• Max. frequency 10 kHz
• Flow rate at max. frequency 1 000 g/s
• Output frequency approx. 1 000 Hz
