Inquiry (采购产品): MFC I am interested in purchasing a mass flow controller capable of receiving a continuous analog sinusoidal signal having a frequency range of approximately 0.0001Hz-1Hz, 10Hz... Control signal is 4-20mA... The fluid is compressed plant air at 100psi upstream to 60psi downstream system pressure... Pipe diameters are 1" upstream down to 3/4"... Flow range is 0.1 to 0.4kg/s... The application is experimental focused on research of larger compressed system... Could you recommend a mass flow controller for this application? Thanks for your response...
