Abstract
An electromagnetic flowmeter with variable-frequency conductivity-sensing function for a liquid in a tube includes a first microprocessor, a transducer, flow-sensing device, an exciting-current generating device, a variable-frequency conductivity measuring device, and a switch. The transducer includes coils and sensing electrodes. The switch is electrically connected to the first microprocessor and the sensing electrodes. The switch is selectively connected to the flow-sensing device or the variable-frequency conductivity measuring device according to the signals sent from the first microprocessor. The microprocessor makes the exciting-current generating device to generate an exciting current when the switch is connected to the flow-sensing device. The first microprocessor makes the exciting-current generating device stop to generate exciting current and computes conductivity of liquid when the switch is electrically connected to the variable-frequency conductivity-sensing device.
