COMPARISON BETWEEN ANALOGUE FLOWMETERS AND DIGITAL FLOWMETERS: METHODS, OUTPUTS AND ACCURACY
Analog flow meters and digital flow meters are devices used to measure the flow rate of a fluid (liquid or gas) in a system.
The main difference between an analog flow meter and a digital flow meter lies in the measurement method, output and accuracy.
Analog flow meters provide a continuous indication on an analog scale, while digital flow meters provide precise numerical data and can offer greater versatility in applications and interfacing with other digital systems.
Analog flow meters use mechanical or electromechanical devices to measure the flow rate of a fluid. They can rely on principles such as pressure change, velocity change or volume change to determine flow rate. They provide a continuous or graduated reading on an analog scale (for example, a hand on a dial or a silk-screened scale).
Digital flow meters use electronic sensors to detect fluid flow and transmit the data in digital form.
They provide precise numerical readout and can also offer additional functionality such as data logging, interfacing with control systems or remote communication.
They are generally more accurate than analog flow meters, as the measurement is based on electronic sensors and data processing electronics.
