Abstract:
A magnetic flowmeter transmitter includes a flowtube and measurement circuitry which provides an output related to flow through the flowtube. Output circuitry, such as analog and pulse output circuitry, provides transmitter output(s) related to flow through the flowtube. Output verification circuitry of the transmitter is coupled to the output circuitry and provides verification of proper operation of the output circuitry by analyzing the output signals.
