6.2 Zero calibration (menu C1.1.1)
Following installation, perform zero calibration prior to commissioning the device. Finalise the installation before performing zero calibration. Changes (pipe system or calibration factor) made after the zero calibration may affect the accuracy, making it necessary to perform zero calibration again.
Observe the following for reliable zero calibration:
The measuring sensor should be completely filled with the product at the expected process pressure and temperature.
The product may contain no air or gas, especially when it comes to horizontal installations. Prior to zero calibration, it is recommended that the product be flushed at a high flow rate (>50%), for 2 minutes.
After flushing, re-establish zero flow by closing off the corresponding valves.
Set zero calibration automatically or manually using the operating controls. The converter cover must be installed on the display for automatic calibration.

Storing the displayed zero calibration.
Under certain conditions, zero calibration is not possible and will be cancelled:
The product is still flowing. The shut-off valves are not closed tightly enough.
There are still gas bubbles in the measuring sensor.
Remedy: Flush measuring sensor and repeat calibration
With some media, it may be difficult to perform zero calibration. In such cases, there are various methods to still achieve good zero calibration:
Medium Possible solutions
Media that tend to evaporate or outgas Increase pressure.
Two-phase media (slurries), that contain solids that may fall out.
Two-phase media in which the solids or gas­forming components cannot be separated.
Only fill the measuring sensor with the carrier medium.
Fill measuring sensor with another liquid, e.g. water.

6.5.3 Operation Mode (menu A9)
The device can be switched to "Standby". In this mode, all flow values are set to zero and the counter values are "frozen". The temperature and density values are displayed normally and output via the outputs. The "Standby" indicator on the display shows either the "frozen" counter value or simply "Standby". In this mode, the measuring tubes continue to vibrate and the device can immediately return to "Measuring" mode if necessary.
There is also a "Stop" mode. In this mode, the measuring sensor is switched off and is no longer vibrating. To return to measuring mode from this mode, the measuring device must the complete "start-up" phase again before measurement continues.
The measuring device can be switched into "Standby" mode either using the operating keys on the display or using the control input. You can only switch to "Stop" mode using the operating keys.

INFORMATION!
When changing from the "Stop" to "Standby" mode, the device goes through the entire start-up phase.
In addition to the "Standby" mode, the system control function also allows you to switch to a comparable "Standby" status completely automatically depending on the current operating temperature or density.

6.5.4 Density calibration (menu C1.2.1)
Mass flowmeters are calibrated for density in the factory. Density calibration is based on 2 calibration points. In the factory, air and water are used under reference conditions. The result of this calibration is saved in the converter electronics and stored in the factory settings. Regardless, various applications require maximum accuracy which can only be achieved with on-site calibration.
Available options:

OPERATION 6
On-site density calibration:
Ensure that the device has been properly installed and functions smoothly.
If air (empty) is used as the medium, the measuring tube must be completely dry and free of
liquids and solids. If possible, blow dry air into the measuring tube to empty it.
If liquids are used, flush for a few minutes at a high flow rate to remove gas bubbles.
Set the flow rate to a typical value (50% of the nominal flow is ideal).
If the process temperature is higher than the ambient temperature, wait until the system has
stabilised.
When it comes to 1 point and 2 point calibration, you can choose from the options "empty", "pure water", "town water" and "other". The reference values for the specified products are stored in the converter.
Density calibration has failed if "Density Calib. Error" is displayed. The reason for the error may be indicated on the display. Possible reasons for failed density calibration:
The device is not in "Measuring" mode.
The calibration points are too close together.
One or more calibration points did not pass the plausibility test.
Flow, pressure, temperature or system are not stable?
Please check your system and try again.
If this results in another failed calibration, please contact the manufacturer.
1 Point Calibration
See examples for "Calibration with town water and other".
Select the function using and and then confirm with ^.
If "Other" is selected, the product density must be entered.
1 point calibration is generally sufficient for most applications, such as adapting the density
measurement to a new installation.
Make sure that prior to calibrating the 2nd point that 1 point calibration was carried out and that the result was saved with the dialog "Save Configuration?".
2 Point Calibration
In this case, both reference points are recalibrated (with the products of the system).
With 2 point calibration, ensure that both calibration points entered by the user are accepted.
If the 2nd point cannot be calibrated immediately after the first one, because the 2nd product is not yet available, the device continues to function normally as after the 1 point calibration. In other words, there can be weeks or even months between the calibration of the two measuring points.

6.5.7 Pipe diameter (menu C1.1.3)
The converter can also provide the flow velocity based on a pipe diameter which the customer can freely program. This value can either be the inner diameter of the measuring tube (factory default) or the inner diameter of the process pipe.
6.5.8 Concentration measurement (menu C2)
This menu is used to enter the password to activate concentration measurement (in case the concentration option is purchased) after the meter is delivered.
INFORMATION!
Please refer to the separate concentration manual for further details of concentration measurement.
6.5.9 Flow direction (menu C1.3.1)
This function allows the operator to set the direction of flow in relation to the arrow on the housing. If "Forwards" is selected, the flow direction corresponds to the "+" arrow and with "Backwards" the flow direction corresponds to the "-" arrow on the housing.

6.5.10 Pressure suppression
The pressure suppression eliminates any disruption in the measurement in the event of an abrupt flow switch-off e.g. when valves are suddenly closed. In such cases, surges may occur in the pipe and in the measuring device which could lead to over-vibration. The flow then "swings" back and forth before a stable zero flow is established, as shown in the figure below. This effect occurs mainly in high pressure applications.
OPERATION 6

97
6 OPERATION
In most cases, the amplitude of this vibration is below the low flow cutoff and thus does not affect the measurement. In very few cases, the amplitude is greater than the low flow cutoff (over­vibration) and can cause errors with the counter values.
MFC 400
Figure 6-9: Amplitude behaviour
1 Low flow cutoff 2 Low flow cutoff 3 Pressure suppression 4 Pressure suppression
The pressure suppression function eliminates this effect by activating a larger low flow cutoff level for a short period of time. The pressure suppression is activated when the flow falls below the standard low flow cutoff level for the first time. For a programmable period of time, (can be programmed in menu C1.3.2), the pressure suppression threshold is added to the standard low flow threshold (can be set in menu C1.3.3).
The optimal setting values for pressure suppression depend on the current operating conditions and can thus only be determined on-site through testing.

6.5.12 2 Ph. Threshold (menu C1.5.3)
The threshold for the 2 phase signal can be set in this menu item. This makes it possible to output a status signal indicating the presence of gas bubbles in the process. There are no default values for this threshold. This means that the operator must adapt this value to suit his application. This can be done, for example, by programming the 2 phase signal at the current output and registering which threshold makes sense for the respective process for a certain time period.
Example regarding the detection and notification of a two-phase disturbed flow (e.g. gas bubbles in paints):
