6.4 Calibration functions
6.4.1 Zero calibration (C1.1.1 Calibrate Zero)
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 flow 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 signal converter
cover must be installed on the display for automatic calibration.

Zero calibrations are recorded in the zero calibration log. Log information includes zero offset,
temperature, date and time. Navigate using the ↑ and ↓ keys. Exit the menu using the ^ key.
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 flow sensor.
Remedy: Flush flow 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.
Table 6-15: Zero calibration for difficult media
Only fill the flow sensor with the carrier medium.
Fill flow sensor with another liquid, e.g. water.

6.4.2 Density calibration (C1.2.1 Calibrate Density)
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 signal converter electronics and stored in the factory settings.
Regardless, various applications require maximum accuracy which can only be achieved with
on-site calibration.
Option Explanation

1 Point Calibration One of the 2 saved calibration points is replaced by customer calibration.
2nd Calibration Point Calibration of the 2nd point.

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 signal converter.
The reason for "Density Calib. Error" display may be indicated on the screen. Other possible
reasons include:
• The device is not in "Measurement" 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 or other calibration error display recurs, please contact the manufacturer.
1 Point Calibration
• Refer to 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 Measurement functions
6.5.1 Flow (C1.1.0 Flow)
Flow direction (C1.1.4 Flow Direction)
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.
Process noise damping (C1.1.5 Process Noise Damping)
The flow and density measurements are filtered in order to reduce process noise. The time
constant of this filter can be changed in C1.1.5.
If you require a faster response of the device, e.g. for short batches, you could reduce this time.
This parameter is only available if the device is switched to expert mode (C6.4.5).
OPERATION
6
Low flow cutoff (C1.1.6 Low Flow Cutoff)
The flow sensor provides a low flow cutoff (C1.1.6) which is a percentage value of nominal mass
flow rate. The nominal mass flow rate is available in menu "Test" (B4.6.0).
The low flow cutoff is enabled by default sets all flow measurement variables to zero when the
flow is below the low flow cutoff value entered.
This parameter is only available if the device is switched to expert mode (C6.4.5).

OPERATION
Pressure suppression (C1.1.7 & C1.1.8)
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.
MFC 400
Figure 6-6: Vibration behaviour during pressure suppression
1 Flow switched off
2 Sinusoidal vibration ("over-vibration")
3 Stable zero flow
The pressure suppression function eliminates this effect by activating a larger low flow cutoff
threshold for a programmable period of time. The pressure suppression is activated when the
flow falls below the standard low flow cutoff level for the first time (C1.1.6). For a programmable
period of time (C1.1.8), the pressure suppression threshold is added to the standard low flow
threshold (C1.1.7).
This parameter is only available if the device is switched to expert mode (C6.4.5).
Measurement of flow velocity
The signal converter can provide the flow velocity based on a pipe diameter which the operator
can freely program (C1.1.9). This value can either be the inner diameter of the measuring tube
(factory setting) or the inner diameter of the process pipe.

6.5.4 Detection of 2 phase flow
Due to EGMTM (Entrained Gas Management) the device performs a stable measurement function
between 0…100% gas ratio. The device provides a signal which indicates two phase flow. This
signal can be used for signalling two phase flow according to NE 107 or for approximating the
amount of entrained gas. The signal depends on the amount, distribution and size of the
entrained gas and therefore any threshold has to be adapted on the application.

OPERATION
6.6 I/O configuration
6.6.1 Damp output signals
All digital and analogue outputs provide damping with a digital filter which allows to stabilise the
output. The damping can be individually set for each output by a time constant. However, keep in
mind that the degree of filtration affects the response time of the device in the event of rapid
changes.
The general behaviour of the damping value is:
• Small damping:
- Fast response times
- Fluctuating reading
• Large damping:
- Slow response time
- Stable reading
The damping corresponds to the elapsed time until 63% of the end value has been reached
according to a step function. The time until 90% of the end value is reached in case of a step
response is T90 = τ * 1.8 (τ = damping).
MFC 400
6.6.2 Suppress small flow rates
All digital and analogue outputs provide a low flow cutoff for flow measurements in order to
suppress small flow rates.
If the low flow cutoff has been activated, the respective output is set to zero when the flow is
below the low flow cutoff value entered. The value can be entered as a percentage of the upper
range value or in the case of a pulse output as a discrete flow value.
Two values must be entered. The first is for the operating point of the flow sensor and the second
is for hysteresis.
Condition: 1st value > 2nd value

exceeded load values.
6.6.5 Alarm signalling via current outputs
Current outputs provide an alarm signalling via upper or lower failure current. The alarm signal
is set by default in case of device failure, i.e. if the status signal failure is set. If additional status
signals should be considered, the error condition can be changed:

6.6.6 Pulse output and batching applications
Pulse outputs of the signal converter are designed for minimum latency and suited for use with
pulse counters (mechanical, digital) or provers (e.g. small volume provers).
Select the maximum output frequency according to your counter.
Some custody transfer applications require dual phase pulse outputs. For this purpose pulse
outputs from two terminals can be paired. Terminal pairs A and B or D and B can be used.
In this case, the frequency is limited to a maximum of 5000 Hz.
In this case, perform the following settings:
• Configure pulse output terminal A or D
• Set "Output B" to phase shifted mode in menu C2.3.10 by choosing the base pulse output (A or
D). All functions for output B are set using output D or output A.
• Phase shift relative to output A: set phase shift (0°, 90° or 180°) in menu C2.2.10
Phase shift relative to output D: set phase shift (0°, 90° or 180°) in menu C2.4.10

6.8.4 Locking of configuration
Access authentication
The signal converter has a multilevel access authentication concept which allows to protect the
entire configuration against unauthorised write accesses. The access authentication is disabled
by default, however can be enabled by setting an operator password that is not equal to 0000. In
case of an enabled access authentication, write accesses via any interface (local display, HART
OPTICHECK, …) can only be performed after authentication by entering the respective access
level password (refer to next table). Entering this password only unlocks the currently used
interface but no other interfaces.
