ABSTRACT:
A differential pressure .DELTA.p is detected across an orifice plate in a pipe section. The same differential pressure is also allowed to drive a turbine meter. The turbine meter is conventional and produces electrical output pulses at a frequency f.sub.1 proportional to the volume flow rate therethrough. It then has been found that the properties of a fluid in the pipe section and in the turbine meter may be found automatically by electronic computation of first and second ratios
