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.

A) Automatic Calibration

6.2 Zero Calibration (Menu C1.1.1)

Zero Calibration Log (C1.1.5)

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.

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 Gas-Forming
Components Cannot Be Separated.

• 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:

Only fill the measuring sensor with the carrier medium.

Fill measuring sensor with another liquid, e.g. water.

6.5 Description of Functions

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.

Setting the Operation Mode (from measuring mode):

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 go through 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.

Press and hold for 2.5 s, then release the key.

If “Standby” or “Stop” is selected, the device
immediately switches to this operating state. To return
to the measuring mode, go to menu A9 and select
“Measuring”.

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)

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.

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.

• 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.

6.5.6 Density Mode (Menu C1.2.2)

There Are Four Available Operating Modes
For Density That Can Be Set Here

• Process:

The device measures and displays the current
operating density of the product.

• Fixed:

The device displays a fixed density value. This value
must be entered in menu C1.2.3.

• Referred:

The device calculates the density based on a set
reference temperature.

• Standard:

The device calculates the standard density based on a
set reference temperature and the correction factors k0
to k2, so that a standard volume can be output.

The Following Equation Is Used For The
“Referred” Mode:

ρr = ρa + a (ta - tr)

ρr = Density at reference temperature
ρa = Current measured operating density at current

operating temperature

a = Programmed temperature coefficient/density
gradient

ta = Current measured operating temperature

tr = Reference temperature

The reference temperature must be entered in menu
item C1.2.3. The density gradient is set in C1.2.4.

Calculating the Density Gradient

1. Density

2. Temperature

The Following Equation is Used to Calculate
the Density Gradient

a = (ρD - ρC) / (TB - TA)

The value for the density gradient is generally positive
as an increase in temperature usually reduces the
measured density(exception: water anomaly).

Calculating The Standard Density

The measuring device can display a density which has
been corrected in terms of the standard temperature in
accordance with API 11.1. Standard 2540.

The corresponding reference temperature is entered
in menu C1.2.5. The correction factors k0 to k2 are
entered in menu C1.2.6 to C1.2.8.

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.

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 (over-vibration) and can
cause errors with the counter values.

Vibration Behavior During Pressure Suppression

1. Flow switched off

2. Sinusoidal vibration (“over-vibration”)

3. Stable zero flow

Figure 6-9: Amplitude Behavior

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 Description of Functions

6.5.21 Low flow cutoff

The low flow cutoff can be individually set for each
output and each display line. If the low flow cutoff has
been activated, the respective output or display is set
to zero when the flow is below the low flow cutoff value
entered.

The value can either be entered as a percentage of the
nominal flow of the sensor 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 sensor and the second is for
hysterisis. Condition: 1st value > 2nd value

6.5.23 Dual Phase Pulse Output

A dual phase pulse or frequency output is often
required for custody transfer applications. This
operating mode requires 2 terminal pairs. Terminal
pairs A and B or D and B can be used.

In this case, perform the following settings:

• C3.3.11: Phase shift to D or shift to A

• All functions for output B are set using output D or

output A.

• C3.5.11: Setting phase shift from output B relative to

D, if terminal pair D was selected in C3.3.11. 0°, 90°
or 180° are offered as options. C3.2.11: Setting the
phase shift from output B relative to A, if terminal pair
A was selected in C3.3.11 0°, 90° or 180° are offered
as options.

6.5.24 Timeouts in Programming Mode

Normal Menu Function

If no key has been pressed for 5 minutes in a normal
menu function, the display automatically switches to
measuring mode. All changes are lost.

2. Time

3. Currently indicated flow

4. Display set to zero

5. Currently indicated flow

6. Positive hysteresis

7. Operating point

8. Negative hysteresis

6.5.22 Time Constant

To better process widely fluctuating measured values
in the device, the measured values are digitally filtered
to stabilise the output. The time constant can be
individually set for each output, the first line of the
display and the density measurement. However, keep
in mind that the degree of filtration affects the response
time of the device in the event of rapid changes.

Short Time Constant Fast response times

Fluctuating reading

Long Time Constant Slow response time

Stable reading

Test Function

In test mode, the test function is finished after 60
minutes.

GDC IR Interface

If the GDC-IR connection is activated, it is cancelled
after 60 seconds if no connection is established. If the
connection is interrupted, the display can be operated
again after 60 seconds using the optical keys.

6.5.25 Output Hardware

Depending on the hardware modules used (see CG
number), it may be possible to change the output
options on terminals A, B, C or D in the menus C3.1.x.
For example: A pulse output to a frequency output or a
status output to a control input.

The available options are determined by the hardware
module used. It is not possible to change the type of
output, e.g. from active to passive.

The time constant corresponds to the elapsed time
until 67% of the end value has been reached according
to a step function.

6.6 Status Messages and Diagnostic Information

The error messages for the device are divided into
status groups, each with one status signal. There are
16 status groups with fixed status signals and 8 groups
with variable status signals. To facilitate identification of
the problem source, the status groups are then divided
into the groups: Sensor, Electronics, Configuration, and
Process.

The variable status signal can be changed in menu
C1.5.7 to C1.5.14. Changing the status signal to
“Information” switches off the message.

Each status message (= status signal) has a specific
symbol, which is displayed with the message. The
length of each message is limited to one line.

Symbol Letter Status Signal Description and Consequence

FF Failure No measurement possible.

S Out of Specification Measurements are available but are no longer sufficiently accurate and

M Maintenance Required Measurements are still accurate but this could soon change

C Function Check A test function is active; The displayed or transferred measured value

does not correspond to the actual measured value.

All status messages are saved in the status log (menu
B3.1). Use the ↑ and ↓ keys to navigate through this
list. Use the ^ key to exit the list.

The status screen shows the status groups of all errors
that have occurred since the last time the status screen
was opened. All errors that are not current disappear
after two seconds. They are shown in the list in
brackets.

should not differ by more than 2%.

6.8.5 2 Phase Signal (Menu B2.14)

The value of the 2 phase signal can be read in this
function. For applications that must detect 2 phase
flow, an alarm level can be programmed. This alarm
level depends on the application and the process and
can thus only be set on-site under current operating
conditions during flow. For detailed information refer to
2 Ph. Threshold (menu C1.5.3) on page 75.

open the plastic clips that hold the display.

• Remove the 2 locking screws.

• Carefully pull the electronics almost completely out

of the housing.

• Remove the 2 connecting cables from the electronics

before removing the signal converter electronics to
be replaced.

• To insert the new electronics, first connect the two

connecting cables to the electronics.

• Carefully push the electronics back into the housing.

• Tighten the two locking screws again and secure

the display. The measuring system recognises the
hardware replacement when the power supply is
switched on.

8 TECHNICAL DATA

8.1 Measuring Principle (Twin Tube)

Static Meter Not Energized and with No Flow

1. Measuring tubes

2. Drive coil

3. Sensor 1

4. Sensor 2

A Coriolis twin tube mass flowmeter consists of two
measuring tubes 1 a drive coil 2 and two sensors (3 and

4) that are positioned either side of the drive coil.

Energized Meter

1. Measuring Tubes

2. Direction of oscilation

3. Sine wave

When the meter is energised, the drive coil vibrates
the measuring tubes causing them to oscillate and
produce a sine wave 3. The sine wave is monitored by
the two sensors.

8.1 Measuring Principle (Twin Tube)

Energised Meter With Process Flow

1. Process flow

2. Sine wave

3. Phase shift

When a fluid or gas passes through the tubes, the
coriolis effect causes a phase shift in the sine wave
that is detected by the two sensors. This phase shift is
directly proportional to the mass flow.

Density measurement is made by evaluation of the
frequency of vibration and temperature measurement is
made using a Pt500 sensor.
