ELECTROMAGNETIC SENSOR OF CONSUMPTION Russian patent published in 2006 - IPC G01F1/58 

FIELD: the invention refers to measuring technique and may be used for measuring consumption of cold and hot liquids primarily in pipelines of water supply.

SUBSTANCE: the sensor has a measuring tube out of nonmagnetic and nonconductive materials enclosed with a steel tubular body forming a cavity in which there are two pole shoes and excitation coils. One of the pole shoe is fulfilled hollow, coaxially with it on the tube of the body there is a socket on which an output box is fixed. Wires from excitation coils and pairs of electrodes are tapped through the hollow pole shoe and the socket and are connected to transitional clamps in the sections of the tapping box. In the tube of the body there are two openings through which at vacuum impregnation of coils with heat-resistant material compatible according to its physics-chemical properties with electrically insulating wires of coils and lead wires inundated compound out of heat-resistant materials and also compatible with electrically insulating wires of coils and lead wires is placed in the cavity for locating coils and electrodes and also into the hollow pole shoe and the socket.

EFFECT: increases reliability at long term exploitation in wide diapason of temperatures and humidity of environment, simple in manufacturing.
