What is the magnetic flow meter electrodes resistance range, specially for 2 inch size

 

You can't find a specification value for a magmeter's electrode resistance because no one cares what that value is except the manufacturer's electronics designer.

What are you really asking about? The minimum conductivity of the liquid in the magmeter tube? That's a number spec'd by the manufacturer on the spec sheet.

Or some other value?

 

thank you Mr.David
I'am asking about Krohne Optiflux 4300 magnetic flow meter,that's what is the platinium two electrodes resistance must be

 

Magflow meters rely on flowing conductive fluid. The current flow is minimal so unless you have a non-conductive buildup on the electrodes, you'll get a reading. There are a variety of insitu electrode cleaners.

 

Magnetic flow meters use electrodes to measure the flow of a conductive liquid through a pipe. The resistance of the electrodes can vary depending on the type of flow meter and the size of the pipe.
The resistance of the electrodes in a magnetic flow meter can range from a few ohms to a few hundred ohms. For a 2-inch size pipe, the resistance of the electrodes is likely in the lower end of this range, potentially around a few ohms. It is essential to note that the actual resistance of the electrodes can vary based on several factors, including the material of the electrodes, the type of conductive liquid being measured, and the specific design of the flow meter.

 

The conductivity of the electrodes is in the micro-ohm level, while the voltage being sensed is developed by the conductivity of the fluid as it flows through the meter consisting of an insulating liner abd electrodes, under the influence of magnetic fields.
