Use

The meter detects moving electrical charges that are produced, for example, through friction with other objects, such as the pipe wall. (solid lining/buildup will not be detected)

The sensor electronics of the FLOWguard V-series are used in conjunction with sensor mechanics of the ESR series… for monitoring solids flows in pipelines, such as pneumatic conveying systems or drop sections in the throughput range from a few g/h to many t/h.

Faults or plugs in conveying systems for powders, granules, pellets and other bulk materials are detected at an early stage and thus avoided. This helps prevent system malfunctions, such as clogged pipes, material loss, idling or other serious problems.

Function

A multitude of sensor mechanics units makes process coupling very easy and allows cost effective solutions for almost any monitoring application – also in existing conveying systems. The advantage of this modular concept also appears in case of refit or exchange. moving The device is not applicable for solids which build up an electrical conducting layer on the sensor through friction or deposition.

The measuring principle is based on the detection of electrical charges, which, e.g. due to friction on the wall, naturally sit on the particles of the solid flow. Stationary solids are not recorded.

A variety of different sensor mechanics makes process coupling very easy and allows cost-effective solutions for almost any monitoring task – especially in existing plants. Further advantages of this modular design can be seen in replacement, retrofitting and upgrading.

The device cannot be used for products that form an electrically conductive layer on the inner wall due to abrasion or caking.

Mounting and Installation

The device is not applicable for solids which build up an electrical conducting layer on the sensor through friction or deposition.
