A digital water flow meter measures the flow rate and displays the readings. You will not have to do any calculation to get the data in volume or mass. The meters are used to get the flow of water through a channel. Digital flow meters have sensors such as turbine, venturi, orifice plate, thermal mass, etc.
Flow meters can either measure the volume or mass of a fluid flowing through a channel. A flow meter needs to have a digital display to be called a digital water flow meter. In short, all flow meters can be digital as long as it displays the readings in a screen.
Below are the are factors you need to know about digital flowmeters with output. Keep them in mind before you settle for one.
Accuracy
Accuracy is vital in all liquid flow uses. But, the degree of accuracy needed varies from one industry to the other. For instance, in the medical industry, any error above 1% can be fatal. Since you are using your digital water flow meter in the water sector, the accuracy will depend on water use.
Water for home use is treated with chlorine and other agents. The inputs may harm the users if they are in excess. Also, if you add little than the needed amount, it may not be enough to kill the germs. Thus, your digital water flow meter with output should have a small range of accuracy. The pros of the digital water flow meter are that they are more advanced than other flow meters. Their accuracy levels are high, so you do not worry when buying one.
Repeatability
Another crucial factor you should know about digital water flow meters is repeatability. The meter will not work well if it has high accuracy and low repeatability. Thus, it is best if you knew that it does not depend on accuracy and vise versa.
Thus, when you check the accuracy, look if it will give similar data over time. Since there are no maths and summing up, you may end up reading the wrong data. It is due to data that is not consistent.
Price
The digital water flow meters are easy to use. This is because of their advanced technology that scraps the calculation steps. Thus, they are more expensive than the regular flow meter. But, there are varied qualities in the market. All of them differ in price. You should therefore buy a good quality digital water flow meter with output. You want to enjoy your investment without any hitches.
Mass or Volumetric Units
Some water uses require mass data, while others require the data to be volume. You need to know your flow rate requirements before you buy a digital water flow meter. The advantage is that there are meters for both unit representations. It will not be hectic to get one.
Conclusion
The points above are vital when you need to get a digital water flow meter with output. Thus, remember to keep them on your fingertip. You do not need to know the tips only when you want to buy the meter. You may need to help out a friend. Also, the information is crucial should you need to upgrade your flow meters.
