MAG-VIEW 4..20mA calculations
The signal current corresponds to flow rate of the instrument..png) Need to know the flow with corresponding mA output?
Need to know the flow with corresponding mA output?
Flow = ( (mA − 4 ) / 16) × ( Vmax − Vmin ) + Vmin
Need to know the output mA flow with corresponding flow?
mA=(16*(Flow-Vmin)+4*(Vmax-Vmin))/(Vmax-Vmin)
Example MVM-005-QA
Flowrate 0 .. 5 l.min
What is the flowrate with 12mA?
((12mA - 4)/16)*(5-0)+0= 2.5 l/min
What is the flowrate with 2.5 l/min
(16*(2.5-0)+4*(5-0))/(5-0)= 12mA
What is the output when the flow is 0 l/min?
4mA is equel to 0l/min flow, this is to easily detect of their is a fault with the instrument.
The QA versions has a flow range and max flow rate.
The MVM-005-QA has a flow range of 0..5 l/min but a max flow rate of 6 l/min.
The QA series has a current output cap of 21.5mA.
Max current output flow is 5.47 l/min, if you need the 6 l/min as output please use frequency signal.
