Measuring chamber body does not have electromagnetic flow transducer of inside lining

The utility model relates to an electromagnetic flow transducer's institutional advancement will solve that current sensor structure complicacy is difficult to the streamlined production, manufacturing cost is expensive, has restricted the application promotion of high -performance electromagnetic flow transducer in heat supply metering device field technical problem, belongs to electromagnetic type electron water gauge technical field. Its characterized in that: the measuring chamber body adopts the tubular metal resonator of no inside lining, the insulating electrode base that is used for imbedding measuring electrode is put to the internal wall of measuring chamber, measuring electrode with the embedded fixed connection of insulating electrode base, excitation coil adopts E shape silicon steel sheet stromatolite iron core to have the iron core end terminal integral structure of yoke. The beneficial effects are that: adopt the measuring chamber body need not not the inside lining etc. The new technology, decline manufacturing cost can realize streamlined production equipment operation and large -scale volume production and then get into wide commercial market field having created the condition for electromagnetic flow transducer. Be suitable for the electromagnetic type calorimeter as detecting heat -carrying fluid flow very much.
