Flowmeter quality and service life length many consumers do not grasp the quality of the flowmeter and service life length.Let me tell you a little about it.
Choosing the right gauge is the most important thing to ensure the service life and accuracy of the flowmeter.Here must be most important to pay attention to the negative pressure and the selection of high temperature.The negative pressure of the flowmeter means the pressure test level, which should be slightly larger than the pressure of the measured medium, generally choose 1 25 times to ensure that it is not easy to produce leakage or accident.Select a range of measurements, that is, gauge limits.If the selection is larger, it will reduce the accuracy of the measurement. If the selection is smaller, it will be very easy to load and destroy the flowmeter.
Should be elected in the specific operation of the total flow of ** most of the 1.2-1.33 times.Because the measuring medium is different, the service life of the flowmeter will be reduced.Here is also a reminder to use the right materials.Below the electromagnetic flowmeter measurement medium inside the relatively typical 2 cases to everyone.
Flow meter
1. Medium: drilling mud, pulp and waste water.
This kind of medium can not be measured with throttling device, due to poor liquidity with small pieces inside, stone is very easy to block high loss.If using electromagnetic flowmeter also pay attention to lining and electrode selection.To wear resistant lining has ductility, polyurethane material vulcanized rubber lining is the best choice.The electrode was 316L.
2. Medium: boiled sulfuric acid, hydrochloric acid, sodium cyanide, sulfuric acid and various solvents.
Such as this kind of highly corrosive medium throttling device, vortex street and other flowmeters are not suitable for measurement.Because the cost of the project is too high and not firm.Electromagnetic flowmeter selection lining teflon electrode tantalum electrode can be considered about the measurement medium requirements.But want to assure installation must exceed specification more certainly, if produce infiltration leakage to be able to endanger the service life of flowmeter.
Since the establishment of our company five years ago, we have sold nearly 900 electromagnetic flowmeters. Up to now, only one of them has had common faults.Due to the controller watch case watchband welding leakage caused a short circuit fault.Our enterprise has sold 750 vortex street flowmeters, and both of them have common faults, which are caused by rough and tumble.Throttling device is about 1600 pieces, no problem.
