Use oscilloscope and measure the output of the flowmeter

Alym123

I have a flowmeter with 3 wires 2 wire of supply and one wire signal 
Flowmeter output is the frequency 

Frequence is proportional to flow

When I tested the flow meter with oscilloscope and measured the output voltage was 24 v but when I tried it with plc the input voltage was 6 v so plc can't read the input as 1 

 Hi Alym123,
My name is Amirjala and I'm trying to use oscilloscope and measure the output of the flowmeter.
As I'm a beginner, Could you please help me and say what should I do from the basics?

thanks a lot

it is enough to click on this user's name in his post and this window appears (my attachment). Generally documentation to your osciloscope describes how to work with eqipment correctly and effectivelly. On other side, internet is full of help in my opinion

What type of Flowmeter do you use?

Give some detailes.
