what is the principle of ultrasonic flowmwter and radar type
flowmeter?
Answer Posted / mohammad rizwan
its work on sonar principal...
the working principal is.when the ultrasonic wave transmit from the transmitter.its travel down the surface.and reflect back to the transmitter receiver...and calculate the time taken...
it is also called TDR(TIME DOMAIN REFLECTOMETRY)system...

A DP transmitter is used to measure the level of an open tank. The drain line of the tank is connected to a control valve, and is configured as, if the level of the tank is 90% the valve should get open 10%. And if the tank level is 10%, the valve should get open 90%. Draw wiring diagram and explain how to configure DP transmitter and control valve using HART communicator. If the span error at output is 1%, what will be the %opening of the control valve at 60% level of the tank?
