RF Card Water Meter have a footvalve installed at the end of the suction pipe which can sometimes malfunction causing the suction pipe and the meter to "loose it's prime". Then if the meter is run without water flowing through it properly the seals can be damaged. Also, the impeller, bearings, and plumbing can be damaged. This is one reason we favor electronic meter protection.
Generally speaking, most RF Card Water Meter cannot provide the higher pressure we prefer for the rotary sprinkler head zones in our irrigation system installations. There is only one centrifugal meter we install that can match or exceed the outstanding performance of the submersible meters, and as of this date that meter is on backorder status due to it's popularity.
meters are commonly controlled electrically by using the irrigation controller, or by using a pressure switch in combination with an air tank. We generally recommend using the irrigation controller as the priority method of control unless the water source is a water well system which feeds both domestic house water and a sprinkler system. If the buyer needs requires a 24 hour on demand pressure system for lake / river water hoses or domestic home water, or, if the source of water is a water well with tank and pressure switch which also feeds the domestic water to the house - - - we have developed a proprietary win-win method of having the best features of both control methods. We know of no other irrigator or meter contractor who offers this "dual control" with the ability to have the irrigation controller have a priority over the pressure switch.
Why is this an advantage ? Because under most common water tank and pressure switch installations the water pressure constantly cycles between the low side of the pressure switch and the high side of the pressure switch - - the "cut in" and the "cut out". This often results in the pressure distribution being rather lower ~ 50% of the time for rotary heads watering turfgrass areas which give their best performance under constant higher pressure. By having the irrigation controller take charge of the meter when an irrigation cycle is running the meter pressure stays more constant at high levels and the constant cycling of the meter on and off is eliminated when the sprinkler irrigation system is running. As always, the irrigation cycle is usually programmed to run at late night or in the wee hours of the morning so as to conserve water from evaporation and not interfere with pressure for domestic uses of water when needed inside the home during the day. This win-win method can also result in longer life for the meter and the meter controller relays as well. We can discuss the numerous advantages of this method with the potential customer on site, in person.
