    Abstract: A system and method are described which are useful for monitoring parameters of drilling fluid within a drilling system comprising a drilling assembly. The drilling assembly is connected between a drilling platform and a wellhead and is useful for more safely drilling a wellbore necessary for hydrocarbon exploration and production by signaling the occurrence of a kick. The drilling assembly comprises a reader module for reading data information of at least one RF tag dispersed in a returned drilling fluid. The data information of the RF tag is transmitted to a controller via a communication link to calculate related parameters of the returned drilling fluid. A method for monitoring parameters of drilling fluid, and an allied blowout preventer for a drilling system are also provided.

    Abstract: An ultrasonic flow meter system includes a conduit defining a channel, at least one pair of first transducers, at least one second transducer, and a processor. The pair of first transducers is mounted on the conduit and includes a transmitting transducer and a receiving transducer for generating a first responsive signal. The transmitting transducer and the receiving transducer are arranged on a chordal path. The second transducer is mounted on the conduit for generating a second responsive signal. The processor is configured to receive the first responsive signal and the second responsive signal, select one responsive signal according to a relationship of the first responsive signal and noise thereof and a relationship of the second responsive signal and noise thereof, and determine a flow rate of a flow medium according to the selected responsive signal. A method for measuring the flow rate of the fluid medium is also provided.
