#CMT# #/CMT# The system (S) has an inbound flowmeter (DB1) and a return flowmeter (DB2) generating respective measurement signals (M1, M2). A processing unit (T) determines fuel consumption of an engine (M) using the measurement signals. A solenoid valve (EV1) is mounted in parallel with one of inbound and return flowmeters to bypass one of the flowmeters in the event of locking the other flowmeter. A control unit (C) detects locking of the former flowmeter from the measurement signals, and controls opening of the solenoid valve in the event of locking of the former flowmeter. #CMT# : #/CMT# An independent claim is also included for a method for controlling a measuring system. #CMT#USE : #/CMT# System for measuring fuel consumption of an engine in a ship. #CMT#ADVANTAGE : #/CMT# The control unit detects locking of one of the inbound and return flowmeters from the measurement signals, and controls opening of the solenoid valve in the event of locking of one of the flowmeters so as to avoid stop of fuel supply to the engine or stop of return of the fuel toward a container during a failure in the flowmeter, in an effective manner while avoiding the need for an operator to move to open bypass valves in case of the failure of the flowmeter. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a functional diagram of a measuring system. C : Control unit DB1 : Inbound flowmeter DB2 : Return flowmeter EV1 : Solenoid valve M : Engine M1, M2 : Measurement signals S : Measuring system T : Processing unit. |
