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: A system and method for calculation of flow rate comprising at least two ultrasonic sensors, ultrasonic transmit receive device, and signal processing device. At least two ultrasonic sensors are installed on the pipe where the fluid is flowing through, and at least two ultrasonic sensors contain different ultrasonic beam paths, further, the ultrasonic beam paths of at least two ultrasonic sensors contain the overlap area. The ultrasonic transmit and receive device is used to actuate at least two ultrasonic sensors, and is used to transmit one or multiple ultrasonic signals to pipes via one or multiple of at least two ultrasonic sensors, further, to receive ultrasonic signal via at least two ultrasonic sensors. The signal processing device is used to process the ultrasonic signal received, further, to calculate the flow rate of the fluid precisely.
