### ⭐⭐ 







  
  
    Not for me
  

*by T***L on Reviewed in the United States on January 29, 2021*

To be honest, I haven't quite tested the functionality / accuracy of the flow meter, rather, first thing I did is measure the mA consumption and that threw me off completely. At ~4.15mA that's just way too much for what could be considered a "sensor", sure you can make a sensor that uses any level of power and it would still be a sensor, but that doesn't mean that its very useful because these sensors are mostly used in battery applications and at 4.15mA that's about 20 days worth of use (~481hrs) with an AA battery of say 2000mAh. If you're running your project with a PSU, then this unit might be ok.However, another point worth noting is that the internal magnet which is essential for getting the pulse readings doesn't appear to be protected by anything, plastic / epoxy, nothing, so that means that it will rust. I looked at it under a microscope and there was nothing covering it. Indeed it could be some alloy mix that has anti-rust properties, but I doubt the chinese will use a quality magnet in something like this.

    Flows <1LPM
  

*by B***S on Reviewed in the United States on December 10, 2019*

This item claims to be able to flow 6L/minute.  I couldn't get more than about 1L/minute through it.  I looked into the inlet port, and there's a flow restrictor molded into the port.  I measured it's diameter at about 1.3mm.  A 1.3mm orifice would flow only 2LPM even with a 200PSI pressure drop, far more than this unit is rated for.

### ⭐⭐⭐⭐ 







  
  
    That you have to use a hard plastic tubing like Pex
  

*by D***Y on Reviewed in the United States on October 28, 2020*

That 3/8 " is the od of the tubing used not the ID
