When brewing the beer, it is necessary to have a flow meter. Where will we use the flow meter in a beer brewery?
The first one is before water inlet for the Mash Tun and also the Sparging water for the Lauter tun.
The next one is after the heat exchanger. We can know how much wort has gone into the fermentation tanks.
Sure many tanks have the sight glass level to help to know the quantity of beer brewing water or wort quantity. But flow meter in a brewery makes it more exactly.
What is flow meter?
Flow measurement is the quantification of bulk fluid movement. Flow can be measured in a variety of ways. Positive-displacement flow meters accumulate a fixed volume of fluid and then count the number of times the volume is filled to measure flow. Other flow measurement methods rely on forces produced by the flowing stream as it overcomes a known constriction, to indirectly calculate flow. Flow may be measured by measuring the velocity of fluid over a known area.
For liquids, various units are used depending upon the application and industry, but might include gallons (U.S. or imperial) per minute, liters per second, bushels per minute or, when describing river flows, cumecs (cubic metres per second) or acre-feet per day. In oceanography a common unit to measure volume transport (volume of water transported by a current for example) is a sverdrup (Sv) equivalent to 106 m3/s.
Modern innovations in the measurement of flow rate incorporate electronic devices that can correct for varying pressure and temperature (i.e. density) conditions, non-linearities, and for the characteristics of the fluid.
Magnetic flow meters
Magnetic flow meters, often called "mag meter"s or "electromag"s, use amagnetic field applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the fluxlines. The potential difference is sensed by electrodes aligned perpendicular to the flow and the applied magnetic field. The physical principle at work is Faraday's law of electromagnetic induction. The magnetic flow meter requires a conducting fluid and a nonconducting pipe liner. The electrodes must not corrode in contact with the process fluid; some magnetic flowmeters have auxiliary transducers installed to clean the electrodes in place. The applied magnetic field is pulsed, which allows the flowmeter to cancel out the effect of stray voltage in the piping system.So a magnetic flow meter is good to use for brewing beer. Hope the above will help you to choose a flow meter when you try to buy beer brewing equipment.
Thanks for your reading.
