ABSTRACT:
A flowmeter system of the type employing a modification circuit responds to a pulse producing volumetric flow transducer and to a signal converter connected to a temperature sensitive transducer for providing a compensated metered output of a corrected series of output pulses relating to a selected reference base or standard temperature for the fluid. The signal converter is connected to the remotely located probe through a connecting circuit and functions to provide an analog output representing the difference between the sensed fluid temperature and the reference or standard temperature while providing dynamic lead length compensation for the connecting circuit. A constant current source is precisely regulated and also selectively adjustable to provide a dual slope approximation of the temperature deviation range with respect to the corresponding probe resistance deviation range at the signal converter output. A monitor responds to malfunctions occurring within the system and calibration circuits permit quick and accurate calibration.
