S7212WF is an electronically controlled flow sensor which is best suited for operation with water or aqueous solutions in industrial and laboratory applications. It is a versatile and cost-effective solution for measuring small flows of liquid over a wide range of temperature and pressure. This technology is widely used in many industries such as automotive, aerospace, medical and electronics.The S7212WF utilizes advanced piezoresistive pressure sensing technology. This technology is based on the use of a thin-film transducer to measure the pressure of the liquid. The transducer is composed of two piezoresistive elements that are bonded on two thin ceramic substrates. The pressure is measured by the approach of one of the two elements against the substrate when a liquid is applied to the transducer. This voltage output is then amplified and processed by an integrated ASIC in a current-to-voltage amplifier.The current-to-voltage amplifier provides an output signal proportional to the flow in the system. This signal is processed in the form of a linear current output which is then used to measure the flow rate, totalized flow volume, and/or temperature. The advantage of measuring flow via the S7212WF is that it can be used to measure small and dynamic flow rates.The S7212WF has been designed to be installed in a wide range of applications, such as water and aqueous solutions, liquid cooling systems, and process control plants. It can also be used in industrial process control applications, such as food and beverage industry, oil and gas industry, and others.In addition, the S7212WF comes with several advanced features and special attributes. It has an optical connection to monitor the sensor’s performance and condition remotely. It also has a built-in self-testing capability that enhances its reliability and accuracy. Furthermore, it features a temperature compensation function to ensure the measurement accuracy at various temperatures.Overall, the S7212WF application field and working principle consist of the combined use of advanced piezoresistive pressure sensing technology and current-to-voltage amplification. It is suitable for applications where small and dynamic flow rates need to be measured. The S7212WF is therefore a versatile and cost-effective solution for various industrial and laboratory fields.
