The invention provides a pressure prediction method of a flow control system, which establishes a relational expression between a pressure value p of the flow control system in a steady state and a flow variation delta Q1 (t) of t∈[0, t, and obtains a flow variation curve delta Q1 (t) of the system under f(t)=F+△F1 and a flow variation curve under f(t)=F+△F2. Official website pressure top measurement can be realized without pressure detection sensor and auxiliary circuit, which saves the time and cost required for installation and debugging of pressure sensor and auxiliary processing circuit, and makes the system structure simpler and the system cost lower.
