ELECTROMAGNET FLOW METRE Russian patent published in 2013 - IPC G01F1/58 

FIELD: instrument making.

SUBSTANCE: electromagnet flow metre comprises a primary flow converter 1, a pre-amplifier 5, a current shaper 6, an analogue-to-digital converter (ADC) 7, a microcontroller 8, an indicator 9 and a reference voltage source 10. Outputs of the current shaper are connected with inputs of the primary flow converter 1. Outputs of the primary flow converter 1 are connected with inputs of the preliminary amplifier 5, the output of which is connected with the first input of the ADC 7. The output of the ADC 7 is connected with the input of the microcontroller 8, the output of which is connected with the input of the indicator 9. The electromagnetic flow metre is additionally equipped with a modulating signal generator 11 and a reference voltage modulator. At the same time the output of the reference voltage source 10 is connected with the first input of the reference voltage modulator 12, the second input of which is connected with the output of the modulating signal generator 11, and the output is connected with the input of the current shaper 6 and with the second input of the ADC 7.

EFFECT: reduced error of measurements.
