Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flowmeters, and more specifically to a gas-liquid dual-purpose electronic flowmeter. Background Art
[0002] An electronic flowmeter is a flowmeter consisting of a sensor and a converter. The measurement principle of the flowmeter is based on Faraday's law of electromagnetic induction. The measuring tube of the flowmeter is a short non-magnetic alloy tube lined with insulating material. Two electrodes are fixed on the measuring tube along the tube diameter direction through the tube wall. When the coil is excited, a working magnetic field with a magnetic flux density of B will be generated in a direction perpendicular to the axis of the measuring tube. At this time, if a fluid with a certain conductivity flows through the measuring tube, it will cut the magnetic lines of force and induce an electromotive force E. The electromotive force E is proportional to the product of the magnetic flux density B, the inner diameter d of the measuring tube and the average flow velocity v. The electromotive force E is detected by the electrode and sent to the converter through the cable. After the converter amplifies the flow signal, it can display the fluid flow rate and output pulses, analog current and other signals for flow control and regulation.
[0003] Some pipelines need to transport both gas and liquid fluids. However, due to the different physical properties of gas and liquid, it is difficult for a single gas flow meter or liquid flow meter to detect both. In addition, the external environment will affect the detection of the electronic flow meter, such as temperature, magnetic field, etc. For this reason, we propose a gas-liquid dual-purpose electronic flow meter.
