1. System overview A measuring point consists of the following components: Evaluation unit (MSE 300) in the DIN Rail housing or field housing • Weld-on sensor socket with air purge connection • Sensor • C1- or C3-Box (optional) • The system can be equipped with up to three sensors. Depended on the number of sensors, different C-Boxes (C1, C3) should be use.

2. Function The PicoFlow is a measuring system which has been specially developed for measuring the quantity of • pneumatically conveyed solids. It is used for very small solid / air ratios. • The intrusive sensor probe is made of solid stainless steel and has an additional ceramic coating.
3. Safety The PicoFlow was designed, built and tested for safety and is shipped in this condition. Components within the supplied system could be hazardous if not unpacked, installed, connected and commissioned by authorised qualified persons. All operating instructions must be read, and understood, before handling the system. Failure to do so will cause the warranty to be revoked.

The edited data is transmitted to the evaluation unit via “Device program”. Critical data concerning the ModBus communication and the calibration must be confirmed before the parameters are transmitted to the evaluation unit: ✔ If, when saving the the parameters in the evaluation unit, the system calibration data is changed, this action must be confirmed by checking “Overwrite calibration”.
6.4 One or more sensor systems Up to three sensors can be connected to a evaluation unit if, for example, a larger flow section needs to be illuminated. In the evaluation unit, the corresponding number of sensors will then be registered and a joint average value will be calculated from their measurements.

PC software. Only according to instructions from personnel of ENVEA Process: If a detailed error analysis is necessary, a copy of all ModBus registers can be stored as a text file in the installation folder of the software by clicking on the sensor dump.
Start-up procedure Basic start-up Upon delivery, the sensor is not calibrated to the product to be measured and must be parameterised when started up. During the process, the mass flows measured by the sensor will be assigned to the display values and output quantities required by the user.
For an evaluation of the recorded log file, it must be opened with Excel or a similar program. The content of each column of the log file is named in the first line. In order to determine the appropriate raw value for a calibration point, the mean value must be determined from the period of the reference extraction.
8. Error signalling For monitoring the availability a wide range of functions for self-diagnostics were integrated, in order to signal various errors: 1. Fatal error (ERR): Fatal errors (ERR) always set the current output to the set alarm value. Technical problems or problems with the complete system are displayed on the touchscreen.
8.1 Compatibility For the PicoFlow system two different software versions for the evaluation unit and associated PC software are available. Technical innovations have caused a supplement of new functions, so that only the corresponding versions can be used together on evaluation unit and PC:...
In case of a defect during the warranty period, defective components are repaired or are replaced free of charge. Replaced parts turn into the property of ENVEA Process. If desired by the costumer that the parts should be repaired or replaced in its factory, then the costumer has to take over the costs for the ENVEA Process-service staff.
