Development of a ball flowmeter for electrically conductive liquid

A variant of a ball flowmeter of an electrically conductive liquid with four electrodes and a balanced circuit is presented, which ensures the initial balance of the converter circuit. Results of development work on the creation of ball flowmeters of electrically conductive liquid intended for automation of production processes and the social sphere of the economy are presented - the use of such flowmeters in heat power engineering, the food and pharmaceutical industries is especially promising. The developed ball flowmeters of electrically conductive liquid have a common design feature. They use a ball with zero buoyancy in a liquid and a helical jet guide apparatus with a coaxially located annular channel. The configuration of the jet guide apparatus is designed in such a way as to minimize energy losses of the moving fluid and prevent breakdowns and turbulence of the fluid at the entrance to the annular channel. The electronic circuit of the primary flow transducer generates an output signal in the form of a rectangular pulse repetition rate proportional to the liquid flow rate.
