Abstract:
It is shown that the transfer into a recording instrument of a measured volume flow rate of low-viscosity liquids in the form of a PWM-signal, and also software and hardware for carrying out the functions of monitoring and self-diagnostics and for eliminating the random component of the errors and subregulation using external crossing components in combination with the use of the M1821BM85A microprocessor, ensures the functional reliability of the monitoring and measuring system, thereby satisfying the requirements for their use in industrial and transport systems.
Keywords:microprocessor  vortex primary converter  pulse-width modulation (PWM)  low-viscosity liquid  volume flow rate
