How u measure the massflow in orifice flow measurement techniques

Answer Posted / Arti Pandey

In orifice flow measurement techniques, the mass flow rate is calculated using the measured velocity and the known fluid properties (density and specific gravity). First, measure the orifice plate diameter and the pipe diameter. Then, take a series of measurements of the fluid velocity at different points downstream of the orifice plate. Calculate the average velocity and use the Coanda effect correction factor to account for turbulence. Finally, multiply the average velocity by the cross-sectional area (calculated from the pipe diameter) to find the mass flow rate.

principle of dead weight tester ?

A PLC is programmed to drive three motors A, B and C as follows : After running motor A for an hour, motor B should get ON and motor A should get OFF. And after running motor B for an hour, motor C should get ON and motor B should get OFF. And after running motor C for an hour, motor A should get ON and motor C should get OFF. (That is, a cyclic repetition with time period one hour) Now, the second condition is: If any motor gone faulty and is tripped, the consecutive motor should get ON and the faulty (tripped) motor should be eliminated from cyclic repetition. The remaining two motors should bear the cyclic repetition of one hour each. (For healthy motor take logic as high and for tripped motor take logic as low) Now, the third condition is: When motor A load(Amps) exceeds 60% of its rated load, motor B should get ON in parallel to motor A. And when both motors A & B are running in parallel, and if their load exceeds 60% of their rated load, motor C should also start in parallel to A & B. [Here the cyclic repetition is eliminated, until their loads become normal(40%)] [Take logic high(1) for load at 60% and logic low(0) for load at 40%] Now draw a flow chart or a ladder diagram to fulfill the above condition.
