1/4 inch Flow Monitor

[Overboard]

Has anyone set up the 1/4 inch version of the flow monitor? I purchased one to put on the supply side of my calcium reactor which uses 1/4 RO/DI type tubing. Seems like the sensor is designed for flexible tubing instead with a compression fitting and has the British style of threading. Trying to figure out how to adapt it to fit my supply line.

Thanks,
Mark

Found a thread on the Neptune site forum. It looks like the RO tubing should push through the nut and then get screwed on, but I sure can't get the tubing through it.

I installed one myself not too long ago. One side is 1/4" tubing and the other side is airline tubing.

Thanks. Finally figured it out. Cut the tube at an angle to push it through, then cut it off square before attaching to,the sensor. Working ok.

Resurrecting this old thread, because I'm having the same problem. 1/4 inch RO tubing does NOT fit snug in the adapter nut for the flow monitor.

I'm trying to find a 1/4 inch BSPP to push connect adapter, but have not had any luck. Any help anyone can offer?

@Terence, any guidance you can provide?

Wrap the end of the tubing with some plumbers thread tape and then put it in the fitting.

Thanks for the suggestion, but relying on Teflon tape to increase the outer diameter seems a bit jerry-rigged though, doesn't it--especially for a Neptune product? I'm a bit incredulous that there is not a method of attachment that is more secure than that.

I did that for air tubing. The actual ro tubing fit in perfect.

That's really odd, because on mine it doesn't

That is strange. Might sound like a dumb question but did you make sure the grip sleeve didn't fall out?

Grip sleeve? I only have a single plastic nut...
