To ensure high-quality water, you definitely need water quality monitoring stations like our friend has mentioned above. You’ll also need measurements such as pH, turbidity, free chlorine, and conductivity. Therefore, the system needs to collect a sample from the process and then do all these measurements.

Usually, one company will provide the entire solution for this sort of process, including the flow meters. If the flow meters work well, you can keep the same technology and just upgrade the devices. However, if you encounter problems, you may want to consider a new working principle or maybe even a new vendor.

For this size pipe and flow, the market has some economical solutions that offer decent accuracy for a low investment. Let’s go over a couple of these options. But remember to make sure they can fit your process and measure your range.

SM6 series electromagnetic flow meter

This device from IFM gives you two outputs with pulse, analog, and others. The installation requires five times the diameter before the meter and two times after. It also has a local setup with push buttons.

Picomag electromagnetic flow meter

This new meter from Endress+Hauser has good accuracy and a handful of choices for integration, such as analog, pulse, and IO-Link. The device requires only three times the diameter for the inlet and one for the outlet – not bad at all. Last but not least, you can use Bluetooth to set it up through a free app called SmartBlue.
