NOTE: It is critical to invoke the zero point calibration after installation.
Every Coriolis Meter must be zeroed in the final installation point with the fluid that will be measured.
Make sure the meter has warmed up for at least 15 minutes before invoking the zero function. Make sure the measuring tube is fully filled with liquid. Turn off the stop valves, make sure the liquid is in a stationary state, and enter password 20 to invoke calibrate the zero point. The zero function is in process when the display indicates "Adjust zero" for about 30 seconds and then reverts to the normal display mode, after you hit the bottom left Enter button to start the function. This function is CRITICAL to allow the meter to determine the resonant frequency of the measuring tube is to determine the density of the fluid within it. This step cannot be skipped. Once this step is complete you will want to confirm the measured density is accurate.
This is done in the main running screen by touching the up arrow (upper right hand corner) and confirm the indicated density agrees with the density of your fluid.
Coriolis mass flow meters directly measure the mass flow and the density of the fluid. The volume flow rate is calculated by mass flow divided by density. If the density measured at the zero point is not accurate, then the flow rates will be affected as well.
