Coriolis flow meters (also referred to as Coriolis mass flow controllers) arevery accurate flow meters designed to measure the flow rate of liquids, slurries, & oils.Our flow meters ship from stock (usually within 48hrs) and are configured for you.
A Coriolis flow meter contains a tube which is energized by a fixed vibration. When a fluid (gas or liquid) passes through this tube the mass flow momentum will cause a change in the tube vibration, the tube will twist resulting in a phase shift. This phase shift can be measured & a linear output derived proportional to flow.

Notes about ZERO Calibration on Coriolis meters.
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 invoke calibrate the zero point as shown below. The zero function is in process when the display indicates "Zeroing, please wait for 30 s" for about 30 seconds and then reverts to the zero uS display mode. 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. 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. We explain what is shown in the manual below for ease of access.
Using the root menu (see Figure 2.14) press ↓ button several times to move to the Menu item “Configuration Press E to enter”. Press E button and enter the password (default password is 000000). To enter the password press ↓ to increment the currently selected digit, to move to the next digit press → button. After correct password entry The screen will say Flow Config Press E to enter. Press E. Next the screen will say Zero Calibration with the zero uS below. Press E to start. The Zeroing message will appear with a blinking N. Use the → to make the Y blink. Press E to start zero calibration procedure. A message “Zeroing?” will appear. Press E to confirm that. Zero calibration procedure lasts for 30 seconds, the count down time is displayed.

All flow meters require that the fluid delivered is free of gas bubbles. The TFM-9005 Gas Eliminator is one way to address this need. Frequently used in oil fields as well as other processes that have entrained gases.
