CGOLDENWALL 1.5 Inch Turbine Flow Meter LCD Digital Display Flowmeter with 1.5" Inlet/Outlet, Flowmeter for Diesel Kerosene Gasoline, Flow Rate Range 10-73.5 GPM

Updated 4/30/243hrs after install in a closed system, radiant heating system, it developed a load rattle. Readings dropped from 7.2 gpm to 6.6.Now I have to undo it from its NPT couplings to look inside and see what happened.Follow up:Removed the unit and inspected the rotor. It was unbalanced by a small blob of teflon pipe seal compound from one of the joints in the system. Replaced the unit and everything works as expected.Note : the NPT threads are a fraction large and the NPT connector "bottoms out" before making a tight enough seal. I filed the male connector slightly and reassembled. All OK now!

The const./install was easy, the meters came online with no issues. I bought both a 1.5" and 1" model to balance water flows between pool propane heater and solar heaters for maximum efficiency heating for our swimming pool. I am not interested in the totalization feature, just the actual instantaneous "flow rate". Instructions are not clear on how to set this up, the 1" meter does have the instantaneous flow in the small font, the main reading totalizes, which is acceptable for me, the 1.5" meter only totalizes on both readings which does not meet my requirements. Do I need a different meter head for the 1.5" meter or is is this a set up issue? Do you have a service number I can talk to a person concerning this? Thanks Jeff

Great Company! The first digital meter we received unfortunately was not working properly. However, I reached out to the company, and they responded immediately. I was given some troubleshooting to do, which failed. They immediately expedited a new meter out to me. We installed it and it is working perfectly.Great customer service!! I highly recommend them..

Tried calibrating. First, you have four screws to remove and hopefully not strip the heads to inset batteries. That done, tried to calibrate. The buttons are not very positive, I had to use my fingernails to get them to contact, so you're trying to get contact for 10 seconds... What a pain. The first attempt to calibrate worked ok. Did a test and needed to recalibrate. It would not get to the calibration mode, so... took out four screws and removed the batteries. Put back and then calibrated. Tried once again to calibrate, but it wouldn't! Just flakey junk. Fix the electronics. Otherwise seems physically well built, poorly designed (batteries) and flakey electronics. On their way back to probably be shipped to the next poor soul...

Perhaps the use of this with pvc plastic would be much easier. But, I was using stainless steal. I probably redid this product 6 times. I usually do 3 rotations with the tape then putty on pipes. One side took 9 rotations and the other 12 with putty to finally stop dripping.Otherwise the flow and digital aspects of the product appear working.

The first meter we received had an issue and they were incredibly responsive and sent a new one out asap. Would defiantly purchase from them. Thanks for standing behind your product.

Used on a diesel tank for farm work. Worked for about a year then stopped working. I assumed batteries quit working however when I took the display off I noticed that the back of the circuit board was corroded/fried.Worked good enough up until then and I always had a bucket over it to keep it out of the rain.

The units work great, easy to install and accurate.
