  • Temperature compensated fluid conductivity piping measurement
    Patent number: H2228
    Abstract: A conductivity sensor positioned in-line between two pipe sections within a cylindrical collar portion of a measurement assembly measures the electrical conductivity of fluid under flow through a passage therein to generate a conductivity data signal, while a separate temperature measurement data signal is generated by a temperature sensor embedded within the collar portion of the measurement assembly in close axially spaced relation to the conductivity sensor. Both of the data signals are fed from the conductivity and the temperature sensors to a data processing system to provide a temperature compensated conductivity measurement readout.
