How to calculate the electromagnetic flowmeter

How to calculate the electromagnetic flowmeter, some customers do not know their own total flow range in inquiry or selection, in other words, only know the size of the specification, will not calculate the total flow.Net make up here say a: even if the manufacturer tells you how to calculate the total flow of electromagnetic flowmeter, but oneself still want to master, because do not master the so-called "fault" for the range of difficult problems will be excited to find after-sales service, in fact are small problems, even not difficult problems of the fault.

So how does electromagnetic flowmeter calculate flow?Let's say I have 500m, right?A pool of water is required to be drained by a pump within 4 hours. How do you determine what caliber of pipe to use?The flow range of the flowmeter can be determined as :500m?Divided by 4 hours is 125m, right?H.The approximate range of pipe diameters can be calculated by flow rate,

That is, the velocity (0.5~8m/3)=125m?Over h, we know by calculation that we have to pump 125m, right?The diameter range of the water in /h is 0.075m0.2975m, that is DN80°DN300. Considering the accuracy requirements of the electromagnetic flowmeter, the flow rate of 2'^4m/s is better. Through calculation, the diameter is 0.105m0.149m, that is DF100DN150.

Here there will be a a error influence factor, is a time when many users do not know, even if know diameter size, also don't calculate flow rate, usually based on at this time the scene of the water pump hm to calculate or measure, but this is not accurate, so the set range is not too accurate, this time take the cumulative flow meter precision compared with the range of the pump, there will be the result of the ascension of the error.That's something to take into account.
