The Turbine flowmeter and electromagnetic flowmeter are usually mentioned by brewmasters in this area. Now let’s compare this two kinds of flowmeters in below:
A. Application comparing:
Electromagnetic flowmeter: Catch the Signal via electromagnetism, no wheel inside, so this is very suitable for high viscosity liquid.. Maximum work temperature: 110℃
Turbine flowmeter: Has wheel inside to measure the signal, so high viscosity liquid easily stuck the wheel, so it is not suitable for wort.
Maximum work temperature: 100℃
B. Material comparing:
Electromagnetic flowmeter: Only the PTFE Gasket will contact the liquid. So it is no matter if the material or the valve body is food grade or not. The Electromagnetic flowmeter with normal material will be good enough for wort/beer/brewing water.
If you wish everything to be perfect, then please choose the SUS304 model whose price is also not higher much.
Turbine flowmeter: It is wheel inside that will contact the wort/beer. However the wheel material must be carbon steel as SUS304 wheel can not catch the signal. So even when we see that the Turbine flowmeter has food grade body, the wheel is still just carbon steel. So strictly speaking, the Turbine flowmeter is not suitable for wort/beer/brewing water which have high requirement to the sanitation level.
Summarize
So if you plan to monitor the flow of the wort/beer/brewing water, the Electromagnetic flowmeter: is necessary.
If you plan to monitory the flow of the glycol water, waste water etc. turbine flowmeter is just good enough.
