The PV74L12-3S L/C module is an industrial-grade pump control unit used to accurately control the flow of liquids and gasses. It is designed for applications requiring low-flow regulation. It features an extremely sensitive response to changing liquid and gas levels, allowing users to accurately control the flow rate.The PV74L12-3S L/C module has an integrated control circuit and is capable of controlling the service flow rate over a wide range. The module has three primary components: an enclosure, a flow sensor, and a control board. The enclosure houses the components of the module and are designed to be waterproof, dust-proof, and heat-resistant. The flow sensor is mounted in one side of the enclosure and is used to measure the fluid being processed. The control board is mounted on the opposite side of the enclosure and contains the circuitry to sense the speed and direction of the fluid and to adjust the flow rate accordingly.Working principleThe working principle of the PV74L12-3S L/C module is based on the use of an induction-type flow sensor. The flow sensor consists of a rotor and a stationary core connected to a capacitor. When the liquid or gas flows through the rotor, an alternating magnetic field is induced, causing the capacitance between the rotor and the core to change. The differential capacitance between the rotor and the core is measured and used to determine the flow rate. The control board measures the differential capacitance and adjusts the flow rate accordingly.The control board also allows users to set the desired flow rate. The user can choose a range of flow rates, from low to high settings. The control board will attempt to maintain the desired flow rate by adjusting the speed of the pump or other components.The PV74L12-3S L/C module is a versatile unit that can be used in many applications. It is suitable for controlling the flow of liquids in water treatment plants, industrial manufacturing processes, and other large scale operations. It is also ideal for controlling the flow of gases in industrial processes, such as welding or oil refining. The unit is also suitable for controlling the flow of air in heating and cooling systems.The PV74L12-3S L/C module is an efficient and cost-effective way to control the flow of liquids and gasses in an industrial setting. It is reliable, easy to install, and simple to use. With its wide range of flow range and accuracy, the module is a great choice for industrial applications requiring precise fluid flow control.
