- Series VMM Construction and function
Danger! Electric current!
Particular care must be taken if the front window of the housing becomes fogged over or discolored because moisture, water or product might seep through the wire sheath into the terminal compartment in the housing!
Ingress protection IP67 is only achieved if suitable and tightly screwed down cable glands
or conduits are used. If the cable glands are only tightened manually water may leak into the terminal compartment in the housing.
Electromagnetic compatibility is only achieved if the electronics housing is closed. Leav-
ing the enclosure open can lead to electromagnetic disturbances.
Further warnings that are specifically relevant to individual operating procedures or activities can be found at the beginning of the relevant sections of this operating manual.

3 Construction and function

3.1 Construction

The VMM comprises a sensor and the display electronics. The sensor is used to measure flu­id media. The display electrodes generate the coil current required for the magnetic field and prepares the induced voltage applied to the electrodes.
The VMM does not need any moving parts to make measurements. The inside of the measuring tube is completely open, allowing the fluid to flow unhin­dered through the measuring tube.
Display electronics:
The display electronics has a backlit LCD. 6 buttons are used for operation. That facilitates easy configuration of the display electronics. Furthermore the display electronics has an analog 0/4 … 20 mA current output, a pulse or frequency out­put and a status output.

3.2 Measuring principle

The magnetic inductive flow sensor operates on the inductive principle, i.e., a direct current is generated by the movement of a conductor in a magnetic field: The measuring pipe of the VMM is in a magnetic field (B). An electrically conductive medium (Q) passes through the pipe. During this, the positive and negative load car­riers are inversely deflected.
A voltage arises which is perpendicular to the magnetic field, which is tapped through both electrodes. The voltage induced during this is proportional to the average flow velocity of the fluid.
The electronics of the VMM converts the induced voltage into a flow-proportional frequency signal.

3.3 Functions

Empty pipe detection:
The electronic display unit has the ability for an empty pipe detection, which can be activated and deactivated. The operating reliability depends on the conductivity of the liquid medium and the cleanliness of the electrodes. As higher the conductivity is, as more reliable operates the empty pipe detection. Insulation coatings on the electrodes surface worse the empty pipe detection.
Safety of operation:
A comprehensive self-monitoring system ensures maximum safety of operation.
• Potential errors can be reported immediately via the configurable status output. The
corresponding error messages will also be displayed on the display of the display elec­tronics. A failure of the auxiliary power can also be detected via the status output.
• All outputs are electrically isolated from the auxiliary power, the sensor circuit and from
each other.

4 Installation of VMM

Before installing, check that
the wetted materials of the device are suitable for the liquid being used
( § 11.2 "Materials table").
the equipment is switched off and is in a safe and de-energized state. the equipment is depressurized and has cooled down. Please observe in particular "Instructions on potential equalization and cathode protec-
tion" ( § 4.2).
Suitable tools:
Use only suitable tools of the correct size.

- Series VMM Installation of VMM

4.1 Installation instructions display electronics

Compact version (standard):
For the compact version the display electronics housing is mounted on the sensor. Therefore no cable is necessary between sensor and display electronics.
Remote version (optional):
The display electronics needs to be mounted separately from the sensor if:
• the mounting area is difficult to access or there is a lack of space,
• medium and ambient temperatures are extremely high,
• there is strong vibration.
The display electronics has to be mounted free of vibrations!
Make sure that the cables are properly installed at high humidity
and wet conditions.
The electrode cable must be fixed. If the conductivity of the medium
is low, cable movements may change the capacity considerably and thus disturb the measuring signal.
Do not lay the cables close to electrical machines and switching elements.  Equipotential bonding must be ensured between sensor and display electronics.
IMPORTANT! Pay attention to the maximum cable length! For the separate version, the minimum permissi­ble conductivity of the medium is determined by the distance between the sensor and the display electronics. The maximum cable length to ensure accuracy is 656 ft (200 m) ( p. 17 "Connecting cables").

4.2 Instructions on potential equalization and cathode protection

4.2.1 Potential equalization

The signal outputs (process outputs and the mains supply of the VMM are galvanic isolated from each other. The housing and the interference filter of the mains supply are connected to PE.
The electrodes and measuring electronics are related to the potential of the function ground FE of the sensor. FE is not connected to PE, but may be connected with each other in the sensor junction box. If the sensor is grounded by using ground disks (grounding rings), these must in connected with the function ground FE.
At a separate assembly of sensor and display electronics the outer screen of the connecting cable is connected to the housing of the display electronics and has PE potential. The inner
screens of the electrode line are connected to FE inside the junction box of the sensor and to
the mass (GND) of the display electronics. Details of all wirings, terminals and drawing can be found in § 5 "Electrical connection".
IMPORTANT! The display electronics can only process the measuring signal interference-free if this voltage is referenced to a fixed potential (ground).
Potential equalization on electrically conductive pipes:
The sensor is electrically connected to the pipe­line in the sense of a potential equalization.
Thus, the pipeline is grounded, and the media and therefore the signal voltage have a solid signal common.
Potential equalization on electrically insulated pipes:
When using pipes lined with electrical insulation,
plastic tubing or concrete conduits, a separate grounding washer is used to ground the measur­ing media. The grounding washer is installed be­tween the pipeline connection and the sensor’s flange and the ring’s inside contacts the media. Contrary to the diagram shown below, one grounding washer on the inflow side is sufficient. If bidirectional measurements are to be taken, one grounding washer must be installed on either side.
Protection washers or protection rings can also be used as grounding component; or special grounding electrodes, incorporated in the sensor, may be installed. Grounding electrodes are more economical than grounding washers. However, it must be ensured that noticeable differences in potential within the equipment are eliminated, other­wise the grounding electrodes will electrolyze and be destroyed.

- Series VMM Installation of VMM
Potential-free installation of the sensor:
If the pipelines cannot be grounded, due to operational reasons, the sensor must be installed voltage free. To do this, a separate cable must be used to electrically connect these seg­ments of the pipeline (min. 11.8 kcmil (6 mm²)).
An electrical connection occurring between the sensor and any material used for the instal­lation must be avoided. Insulating segments must be installed between the sensor and the pipeline (e.g. PVC pipes or similar). Subsequently, grounding washers are used to electrically connect the media with the display electronics. The display electronics must not be connected with the protective ground con­ductor. This may only be done, if the auxiliary power is 24 VDC.
Potential equalization in separate design:
Create the potential equalization in the separate design the same as described in the above sections. For the potential equalization, the display electronics and the sensor are connected to each other through Pin 7 of the connecting cable.

4.2.2 Cathodic protectives

Using a cathodic protective unit to avoid corrosion, which put a voltage to the tube wall, it must be connected to terminal FE. The boards, control panel and internal switches of the display electronics are on the same potential as FE.
CAUTION! Electric current - comply with limits!
According to EN 61010-1:2012 all electrical circuits with „protective safety isolation with­out any protection against contacts” must observe the following maximum voltages:
• Maximum AC voltage (V
) 33 V
eff
• Maximum DC voltage 60 V. Make sure that no higher potential is connected to FE.

4.3 Sensor installation instructions

CAUTION! Risk of malfunction due to external magnetic fields!
Magnetic fields close to the device can cause malfunctions and should be avoided.
Ensure that no external magnetic fields are present at the in-
stallation site of the VMM.
Please observe § 1.1 "Delivery, unpacking and accessories" and the following installation in­structions:
General:
• The VMM can always be installed at any point on the pipeline in the horizontal as well as
in vertical sections. Ideally, the sensor should be installed in a pipeline with a sufficient straight run, both be­fore and after the measuring point.
• Basically, the measuring principle does not depend on the flow profile. You should use
straight inlet and outlet sections according to the inner diameter (ID). An inflow path of 5 x ID and an outflow zone of at least 2 to 3 x ID is required.
• The flow sensor is only suitable for application in completely filled pipe systems. With a
free pipe outlet, the sensor should not be installed in pipe sections that could run empty (e.g., downpipes).
- 14 - © SIKA • Ba_VMM_us • 09/2018
Page 15
induQ
®
- Series VMM Installation of VMM
If the sensor must be installed in a down pipe, ensure that portion of the pipeline is al­ways filled 100% with the media.
• Due to possible accumulation of gases, the sensor should not be installed at the highest
point of a pipeline.
• It must be ensured, that the axes of the electrodes are running
horizontally to avoid erroneous measurements due to deposits or air bubbles on the electrodes. Also, note that in case of deviations from horizontal, the function­ing of the Empty pipe detection ( p. 10) is limited.
Installation in unfilled pipeline:
• If a pipeline is not always filled, or in case of
an open channel (drainage), the sensor must be installed in a siphon. That means the flow tube cannot run dry and is always filled with measured medium.
Installation between tees, valves and pumps:
Always maintain the distance of the pipe's straight run. If these distances cannot be main­tained, flow conditioners must be installed or pipes with smaller diameter must be used.
If several sensors are installed in series, the distance between each sensor must be equal to the length of one sensor. If two or more sensors are to be installed in parallel, the distance between sensors must be at least 3.3 ft (1 m).

- Series VMM
Measures during malfunctions:
In case of malfunctions in the inflow section due to vortexing (e.g. after pipe elbows, at tan­gential inclusions or with a half-open gate before the sensor), measures for normalization of the flow profile are necessary.
The appropriate steps are:
• increasing the inflow and outflow zones
• using flow conditioners
• reducing the inner diameter of the pipe

4.4 Mounting

As a compact device, the VMM is installed directly into the pipeline. With the separate design, the sensor is installed in the pipeline. The display electronics can be attached to the wall with the bracket.
IMPORTANT NOTICES:
• Only use suitable gaskets for installation.
• Observe the flow direction indicated on the type plate and
on the back site of the sensor.
• Observe the mounting dimensions ( § 11.3 “Dimensions
and weights”).
Select an appropriate location for installation
( § 4.3 "Sensor installation instructions"). To ensure the best possible measuring accuracy, a vertical installation position with increasing flow is preferable (no col­lecting of dirt deposits).
Install the appropriate screwed connections at the installa-
tion location.
Insert the VMM together with the gaskets. Connect the flange connections corresponding to the re-
quirements of their use.
WARNING! Risk of injury or material damage!
Incorrect gaskets and connection materials plus improper assembly can lead to injuries
or material damage.
During installation, comply with the requirements that result from your application.  Maintain the required tightening torques.
IMPORTANT! Weather protection required In the case of an outdoor installation, the device must be protected against direct solar irradiation with a weather shield.

Operating modes:
The display electronics of the VMM has two different operating modes:
1. Display. In display mode, measured values can be displayed in various combinations and the same applies to the VMM settings. Parameter settings cannot be changed in this mode. Display mode is the standard (default) operating mode when the device is switched on.
2. Programming. The parameters of the VMM can be changed in this operating mode. After entering the corre­sponding password, either only the customer-modifiable functions (customer password) or all functions (service password) are released for modification.
User interface:
The user interface is hierarchically structured. At the top level you can find the Functional classes which are displayed as headings. It represents a kind of logical groups for values and parameters.
The second level is the menu level and it in­cludes either parameters or further submen­us. The third and lowest level is the parameter level, which only includes parameters.
All functional classes are interlinked horizon­tally, while all sub items of a functional class are interconnected vertically.
Functional classes, functions and parameters:
Functional classes are strictly written in upper case letters (headings). For the functions and parameters at the next levels upper und lower case is used.
The various functional classes and functions are described in chapter "Functional classes (main menu)" ( p. 24).
For the menu level always the first line of the LCD the corresponding heading for the menu item and the contents of second line is context-sensitive: information, YES/NO answers, alternative values, numerical values (with dimensions, if ap­plicable) or error messages.
If the user attempts to modify values for any of these parameters without entering the re­quired password, the message “Access denied” will be displayed. See also "Operating modes" ( p. 22) and "Passwords" ( p. 23).
The various categories for submenu items are described below.
