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.
