Abstract
An automated meter testing system that includes a fluid inlet valve fluidly coupled both to a fluid source and an inlet on the at least one meter. The fluid source provides fluid pressure to move fluid through the at least one meter. A flow control valve is fluidly coupled to the at least one meter opposite the fluid inlet valve. A valve controller that operates the flow control valve. A controller is electrically connected to the valve controller. The controller sends at least one signal to the valve controller to incrementally open or restrict the flow control valve to increase or decrease a flow rate of the fluid through the at least one meter.
Claims9
An automated method of performing a water meter test, the method comprises the steps of:
- fluidly connecting at least one meter to a fluid inlet valve and a flow control valve, wherein the fluid inlet valve is also fluidly connected to a fluid source and the flow control valve is fluidly coupled to the at least one meter opposite the fluid inlet valve, wherein a valve controller operates the flow control valve, wherein a controller electrically connected to the fluid inlet valve, the valve controller, and an interface electrically connected to the controller;
- fluidly connecting the flow control valve to a discharge pipe and a tank;
- registering an identity of the at least one meter into the interface;
- setting test parameters in the controller;
- purging any air that exists between the fluid inlet valve and the flow control valve, and in the least one meter;
- opening the fluid inlet valve by the controller;
- replacing the air, between the fluid inlet valve and the flow control valve, and in the at least one meter, with a fluid;
- dispensing the fluid from the fluid source through the fluid inlet valve, the at least one meter, and the flow control valve;
- setting the flow control valve by the controller to a selective open position so that as the fluid passes through the fluid inlet valve and the at least one meter, the flow control valve is open only to the extent to correspond to a designated flow based on the test parameters;
- depositing the fluid from the flow control valve into a tank;
- recording an initial flow rate meter reading of the at least one meter;
- monitoring by the controller the weight of fluid deposited into the tank;
- monitoring by the controller the flow rate of fluid passing through flow control valve and volume of fluid in tank;
- comparing the flow rate of fluid passing through flow control valve determined by the controller to the designated flow rate based on the test parameters;
- incrementally opening or closing the flow control valve to further increase or decrease the flow rate of fluid passing through flow control valve to match the designated flow rate within a tolerance;
- recording, through the interface, a final flow rate meter reading of the at least one meter;
- and
- calculating, by the controller, a volume deviation based on at least one of the initial flow rate meter reading and the final flow rate meter reading.
