Blue-White FLOWREAD® R-320, 20-120 GPM, Acrylic Flow Meter for 2" ID Pipe, accurate flow rate measurement for residential swimming pools

Easy to install and works great. Easy to read and the directions made it really easy to know where to put it. This is a must for your pool if you are maintaining it yourself, especially if you have a variable speed pump. Just get it.

The product is very simple and easy to install.

If you have a pool heater and getting the proper water flow to meet the optimal heating out of your unit, I highly recommend you spend a few extra dollars and get this. Before I installed it I was just guessing if I was in the right range. With it, unbelievable how much better my pool heater is working. 65⁰ outside and 85⁰ in the pool.

Easy install and seems to work well. Only reason for 4 vs 5 stars, it suddenly stopped working 2 months after install. Contacted Blue White and rep. gave various possible solutions. What worked for me to get blue float unstuck and working again- Removed top plug and max pool pump pressure. Float dislodged and reassembled. Did this at advice from the customer rep. Back in business!

A must have for anyone with a variable speed pool pump. Works great and easy to install.

It was fairly easy to install. The biggest issue was finding a drill bit large enough for drilling the hole. Once that was done installing the meter is just a matter of tightening the hose claps. They have to be equally tighten or it will leak. Just a droll and set the clutch to a low setting. Using an impact may cause overtighting and cracking of the pipe. I had to install on the inlet pipe to get the required distances. Not ideal but it shouldn't make a difference.

Flow meter works Great on my pool, keeping tabs on water flow rate on my pool is important. Works just as described and had speedy delivery.
