Non-contact brine flow measurement using an electromagnetic flow meter and more
Our customer wants to measure the flow rate of a brine stream. It's a closed pipe on the discharge of a centrifugal pump. They don't like magmeters but would consider ultrasonic if it's not "too expensive." I'm unsure of transit time because there may be too much junk in the water. Maybe a Doppler?.
You should find out why they don’t like electromagnetic flow meters because they are usually the best option. Maybe they had a bad experience and now think that all electromagnetic flow meters have the same problem. However, the bad experience could’ve come from the application and not the meter. Finding out may make your job easier. In the end, an electromagnetic flow meter might be the best option for non-contact brine flow measurement.
If the process has junk in the water, and ultrasonic flow meter that uses transit time won’t help, as it has trouble with solids and bubbles in liquids. Now an ultrasonic based on Doppler may work, as it lacks that hangup. You can also consider a Coriolis if you want an easy setup, although it costs more.
