electronic adapter

[procos]

input signal : sinus form or rightangled form
grade : min.2mVref; max 6Vref
frequance : f= K*Q ------ 0-10Hz, 0-1100Hz
K- CALIBRATION FACIENT OF FLOW TRADUCTOR
Q - FLOW
ouput signal : 4-20 mAcc ; 0-10Vcc
undertaking resistence : 0-800 ohm for 4-20mA ; >2000ohm for 0-10V
alimentation : wathever( 220 V , 110V, 24 V, 5V)
any idee is very good.
thanx all.

If I understand your problem correctly, you want to convert the pulsed variable frequency output from a turbine flowmeter to a voltage or current which can be used to drive a meter of some kind.

What you need is a "frequency to voltage converter", try googling for it.
If you are wanting to make something yourself, try the LM2907 IC.
If you want to buy a solution, there are many ready made F to V converter modules available.

sorry
grade : 2mV actual value to 6V actual value

palet turbine intersect magnetic field create of permanent magnet and create one electropower in bobbin.
frequance of this tension = rotation speed of turbine x number of palet
rotation speed of turbine is proportional with flow range
