ABSTRACT:
An apparatus and method for injecting a liquid product or chemical into a main water supply line used for agricultural or industrial purposes. A pressure regulating bypass valve has an inlet side connected to an outlet line of a multi-ganged, diaphragm pump. The pump is run at a constant speed and produces a non-pulsatile flow of product. The bypass line of the valve is connected to an inlet line of the pump. The bypass valve is set at a predetermined pressure, discharging any excess product into the bypass line. The product line at the outlet side of the bypass valve progresses in serial fashion to an electronic control valve, a product flow meter, and a check valve. The output side of the check valve is interconnected to the main water supply line for injection of product therein. A water flow meter is also provided in the main water supply line. A computerized controller samples flow rates within the water supply line and the product line, and manipulates the electronic control valve to effect various proportional or fixed injection rates for the product. The controller is programmed to carry out different predetermined modes of operation through a user-friendly menu driven system using a keypad for mode selection and data entry. The controller also logs all information pertaining to operational aspects of the injection system. A special mode is provided for calibrating the product flow meter to compensate for changes in product viscosity as a result of different product, temperatures, and concentrations.
