VEGA DTM Collection
The VEGA DTM Collection is the adjustment software for all communication-capable VEGA instruments. The software package consists of PACTware, the VEGA DTMs, the VEGA DataViewer as well as various standard communication DTMs.
A Bluetooth driver also enables wireless communication with Bluetooth-capable VEGA instruments like the display and adjustment module PLICSCOM. A VEGA Bluetooth USB adapter is available for PCs without an integrated Bluetooth module.
The full version DTM collection is now free for everyone

The VEGA DTMs
To protect against unauthorised changes to the set parameters, a sensor can be locked via a PIN. The lock applies to the display and adjustment module, DTM adjustment and fieldbuses.
With the “PINs and Codes” service provided by myVEGA, access codes and instrument codes can also be stored securely. Access from any adjustment device is convenient and possible at any time.
- Sensor status
- Measured value status
- Status of additional measured values (electronics or measuring cell temperature)
- HART communication status messages
- Drag pointer with maximum and minimum measured value, including time
- Status signals according to NE 107 and VDI/VDE 2650
- Instrument documentation as PDF – for saving or printing
- Measured value memory:
The measured value memory in the instrument stores the measured values over a certain period of time and can be read out at a later time.
- Event memory:
The event memory saves all events that have occurred in the sensor, such as error messages or parameter changes. These events can be read out from the sensor at any time with date and time stamp, providing an overview of the instrument status.

Functions of the VEGA DTMs
Under “Application”, the sensor is adapted to the particular ambient conditions the measuring task is operating under. In dependence on the entries made in this window, certain parameters are automatically set to enable optimal measurement. It is therefore advisable to select the setting that best suits the conditions the sensor will face.
- Medium type: “Liquid” or “Bulk solid”
- Medium: Depending on what the user selects under “Medium type”, a number of appropriate media are listed that the user can choose from.
- Application: Select the appropriate one from among various typical applications
- Vessel height/Measuring range: The vessel height or, in the case of applications not inside a vessel, the range in which the measured product moves (measuring range) is entered here.
Distance measuring devices determine the distance to the medium surface, not the actual filling level in a container. In order to indicate the filling level, the measured distance must be assigned to the height of the medium as a percentage value. This calibration is then used to calculate the filling level.
Linearisation is necessary for all tanks where the tank volume does not increase linearly with the level, for example, in a horizontal round tank. The linearisation curve indicates the relationship between the percentage filling level and the container volume.
The following linearisation curves are available:
- Linear, horizontal round tank, spherical tank
- Flow devices: Palmer-Bowlus Flume, Venturi flume, trapezoidal weir, rectangular spillway, V-notch, triangular spillway
A linearisation assistant supports the calculation of complex tank geometries.
If the volume is not to be displayed in percent but, for example, in litres or kilograms, an additional “scaling” is required.
The current output of a sensor is used to transfer the measured values to an evaluation system, e.g. to a PLC, a process control system, a measured value display or a controller.
In the case of a sensor in two-wire design, the sensor supply and the measured value transmission are carried out via a common two-wire cable.
The menu language, the displayed measured variable and the appearance of the measured value are selected in the “Display” window.
Setup and commissioning
Saving instrument data
VEGA offers the option of managing the data locally on an end device or saving it in myVEGA via a personal account. Saving in myVEGA provides the advantage that the data is available to the user on all end devices and at any time via the VEGA website.
(1) A backup of all instrument data can be created via PACTware/DTM as well as the VEGA Tools app.
(2) The backup files and documents are first saved locally on the device.
(3) Anyone who is logged into myVEGA on the respective end device can easily send the backup data to myVEGA.
