Smart Valve

Question

Does anyone have a smart valve installed ? We have been looking at installing one, so far everyone that I have talked to, don't know to much about them. This device puts back pressure on your incoming water meter, which will make it more accurate

This is a city meter the feeds my plant, PSI is around 50-60 depending on the hour. There is alot of air in the water lines. Every house of building have very similar type of meter. These meters read any type of flow that goes through. So we only only want to measure water and not the air. Current water bill is around $20K a month. This smart valve should get it down but 15%... Valve is around 10K.....

Hi Greg,
Could you specify what does “making a water meter more accurate” mean? What kind of water meter do you have? Static/mechanical piston/velocity etc.?
The error curve of water meter may vary depending on the flowrate regime but it is not really related to pressure. If what you mean by back pressure is something that resulting water hammer, then it will damage the meter not making it more accurate. Moreover, you cannot have higher pressure on your outlet (downstream) of your water meter since it will cause a backflow.
If you mean the smart valve is a valve  with a controller that can adjust the flowrate by itself and able to mintain the flowrate in the optimal operating flowrate of your water meter, then it might help to get better measurement accuracy.
