FIELD: measuring engineering.
SUBSTANCE: signal transducer is supplied from a remote power source in the base system. The control circuit in the signal transducer set a signal to the control device which excites oscillations at least of one pipe of the Coriolis flow meter. The circuit for transducing the signals from tensometers secured to a pipeline in the signal transducer generates information on the parameters of the flowing fluid. The protection circuit of the base system and the circuit of the protection of the flow meter in the signal transducer does not allow the power exceeding a given threshold of guaranteed safety to be supplied to the wires connecting the signal transducer with the base system and control device and tensometers.
EFFECT: enhanced safety.
