Mounting and installation 4.1 Supplied equipment MSE 300 in the DIN Rail or field housing • Sensor • Operating Instructions • C1-Box (optional) • 4.2 Required tools Appropriately sized spanner or ring spanner • Tools for electrical connections • 4.3 Mounting of the sensor The sensor has to be mounted as follows: Mounting in horizontal position is also possible. - Page 7 Attention! Before installing the sensor, it is essential to check whether in the transition range from pipe and • measuring pipe a burr, offset or seal extends into the free area. Possibly any protrusions in the pipe must be removed before mounting the sensor. It is always to ensure that the material enters the measuring tube continuously.

Page 31: Start-Up Procedure
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. -
Page 32: Easyflow Calibration
7.1 EasyFlow calibration The EasyFlow calibration calibrates the sensor to a known throughput. Every calibration point should be use at different mass flow, so the sensor can calculate a linearisation between this points. If there is no opportunity for two different calibration points, the system use a virtual zero point. -
Page 33: Datalogger Function In The Software
For the calibration of density and speed up to five calibration points can be set. Under 2.8.n Calibration point, the loading of the sensor in % is now specified and assigned to the appropriate raw value in 2.8.n Raw value. Subsequently, the same procedure is performed with the speed calibration. -
Page 34: Adjusting The Measurement Values
A zero offset is in most cases a process problem, for example caking in the measuring tube. For processes with caking materials, there is the possibility of a cleaning flange. Please get in contact with ENVEA Process for more information. -
Page 35: Error Signalling
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. -
