Subsea multiphase flow meter detector retrievable electronics

An apparatus and a method for its use allow selective installation and removal of a canister such as one containing interface electronics to a mating connector on a housing, such as one containing a subsea multiphase flow meter sensor. The separately retrievable canister may contain multiphase flow meter detector electronics and is sealed, waterproof, and preferably light-weight. Installation and retrieval may be via use of an ROV and an alignment guide which acts as a guide to aid in correct positioning of the canister. The canister may be cooled by surrounding sea water and/or by insulation. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope of meaning of the claims.

Flow meter

A compact and light flow meter having a rapid response includes a main body having a groove portion opened in the upper portion and also having connecting portions for communicating the groove portion and the exterior at both ends of the groove portion; a detachable cover body sealing the opened upper portion of the groove portion having a rectangular sectional shape in which a measured fluid is flowed; and a circuit substrate coming in close contact with the external face of the cover body. A sensor hole opened to the measuring chamber is arranged in the cover body; and a flow sensor is arranged in the circuit substrate so as to be arranged within the sensor hole and set a detecting face to face the measuring chamber.

Low power ultrasonic flow meter

A flow meter is powered by a loop power supply which supplies a supply voltage. A load is powered by a load voltage and includes at least a processor for calculating a flow rate, an ultrasonic transducer power circuit, and an ultrasonic transducer receiving circuit. A power regulating circuit is disposed between the loop power supply and the load. The power regulating circuit includes a power converter responsive to the supply voltage to vary the load voltage in response to a control signal, a safe storage device between the converter and the load for storing power when not needed by the load and for delivering power to the load when required by the load, and a control subsystem for providing the control signal to the converter based on the setting of the loop power supply by the load. A power management subsystem is configured to detect the load voltage and to reduce the power consumption of the load at one or more predetermined set points.

HIGH PRESSURE RETENTION VORTEX FLOW METER WITH REINFORCED FLEXURE

A vortex flow meter for measuring fluid flow has a conduit for carrying a fluid. A region of reduced thickness is formed in a portion of the conduit. A shedding bar disposed in the conduit is coupled to the region of reduced thickness and is configured to apply a rocking motion to the region of reduced thickness about a pivot line in response to flow of the fluid. At least one reinforcing rib on the reduced thickness portion preferably extends parallel to flow of fluid.
