An intelligent flow controller, as an advanced fluid control component, has its performance and characteristics mainly described by a series of technical parameters. These parameters are crucial for evaluating the performance of the intelligent flow controller, selecting the right model, and its application. Below is a brief introduction to the main technical parameters of an intelligent flow controller.
1. Flow Range
The flow range refers to the range of fluid flow that the intelligent flow controller can regulate under normal operating conditions. This parameter is usually expressed in terms of mass flow or volumetric flow, depending on the specific application requirements.
2. Working Pressure and Temperature
Working pressure refers to the maximum fluid pressure that the intelligent flow controller can withstand under normal operating conditions, while working temperature refers to the ambient temperature where the controller operates normally. This is especially important for fluids sensitive to temperature.
3. Power Supply and Signal Input
Intelligent flow controllers generally require an external power supply and also need control signal input. The voltage and current of the power supply, as well as signal voltage range and input impedance, are important parameters.
4. Response Time
Response time indicates the time it takes for the intelligent flow controller to respond to control signals. A faster response enables the controller to better follow dynamic changes and improves the system's control performance.
5. Repeatability and Linearity
Repeatability refers to the consistency of output flow or pressure when the same input signal is applied multiple times. Linearity describes the relationship between the input signal and the output flow or pressure. Ideally, linear relationships make the system control simpler.
6. Electric and Pneumatic Protection
The electrical and pneumatic parts of the intelligent flow controller often require certain protection functions, such as overcurrent protection, overpressure protection, and underpressure protection, to ensure system stability and safety.
