At FloRight Pump & Controls, we pride ourselves on carrying top quality equipment so that we can build you the best possible pumping system. This includes the state-of-the-art McCrometer FPI electromagnetic flow meter! While there’s no true “one size fits all” flow meter, the McCrometer mag meter is still an excellent choice which can be deployed in a wide range of scenarios. It’s one of our go-to choices when designing custom setups.
To learn a little more about this mag meter, read on!
How Do Electromagnetic Flow Meters Work?
Mag meters utilize Faraday’s Law of Electromagnetic Induction. In short, the meter creates a weak EM field within the pipe being monitored. As liquid flows through the pipe, any conductive particles within that fluid cause minor fluctuations in the voltage across that field. With the right calibration, this can be used to deduce the overall liquid velocity, at accuracies of ± 0.5% or better.
This is a highly elegant design and allows them to have several major benefits.
The Benefits of McCrometer Mag Meters
- Obstruction-free design
A magnetic flow meter attaches to the outside of the pipe, so there is absolutely no obstruction within the pipe itself. This also carries the secondary benefit of making them extremely easy to install, usually only with a hot tap. There’s no need to shut down the flow.
- Low maintenance needs
Mag meters have no moving parts, which greatly reduces the need for ongoing maintenance. This gives them a lower long-term TCO compared to most other options in flow meters.
- Few size restrictions
Most in-pipe flow meters struggle to handle larger pipes or else become prohibitively expensive to construct. The overall design of the electromagnetic meter means that they can work with even extremely large pipes, which other meters can’t handle.
Are There Downsides to Mag Meters?
Very few. The biggest issue is that, for them to function properly, the liquid must contain conductive particles. For example, de-ionized water cannot be measured with these meters. Therefore, depending on circumstances, the type of liquid being monitored may force the use of a different style of meter.
Also, some older models used a liner which could potentially come loose, but modern designs – like the McCrometer FPI – don’t have this issue.
