Flow meter selection

Can a flow rate of 27.5% hydrogen peroxide be measured using an electromagnetic flowmeter?
The conductivity of hydrogen peroxide is higher than that of ordinary pure water, so using an electromagnetic flowmeter is definitely no problem. However, for ordinary electromagnetic flowmeters, there may be a requirement that the conductivity of the medium be at least 5 or 10 uS/cm; therefore, I recommend using an electrodeless capacitive electromagnetic flowmeter. When testing hydrogen peroxide, it is advisable to avoid using flow meters with throttling elements or obstructions within the pipes; especially under conditions of high concentration and high temperature, hydrogen peroxide can partially decompose due to the disturbances caused by these elements in the pipes.
Sure, we’re using it and there are no issues
