Maxflow
Measurement for Bulk Solids for High Flow Rates

General

MaxxFlow is a measuring system especially developed for the measurement of high flow rates.
Due to its completely open cross-section and its small height, the MaxxFlow is applicable everywhere, where so far only complex mechanical solutions, e.g. impact weighers or sensing plate systems were possible.

The installation of the MaxxFlow can be made easily - no matter - how the configuration of the pipe is.SystemA complete measuring unit consists of the following components:

• Sensor (Measuring pipe) for installation into the pipe
• Evaluation unit MFE 100

The evaluation unit is connected to the pipe by means of a 5-wired, shielded cable. The maximum distance between pipe and evaluation unit is 300 m.There are two types of MaxxFlow.
It can be implemented alternatively for round or rectangular cross-sections of a pipe. For round cross-sections following specifications are available with DN 150/200/250 mm . For the rectangular specifications 150x150/200x200/250x250 mm. Other sizes of both variants on request. An optimal condition is given, if the filling degree of the sensor is at least 20 %.

Function

In the measuring pipe a homogeneous measuring field is produced by special linking of a high frequency, electromagnetic alternating field.

Solids, which are within this measuring field, absorb the energy of this alternating field. This leads to a measuring signal according to the concentration of the material to be conveyed in the measuring pipe (kg/m3). By means of the same sensor technology within the measuring tube on two further places the change of the alternating field is measured. These two sensors have a defined distance.

The evaluation unit with its integrated correlator determines the time of the conveyed material between the two sensors. With the known distance the velocity of the solid is then determined (m/sec).
