Product specification

Evaluation unit for flow measurement system based on microwaves

 

Description

The  evaluation computer FLOCON 21 forms, together with one of the sensors DR-xxx, a contactless flow measurement system for many applications in the transport of dry solids / bulk materials (sand, powder, dust) in pipes (pneumatic transport or in applications with free-falling material).

The  measured variables are speed and mass flow, both can be output at 0 / 4-20mA current outputs.

Depending  on the application, the system can also measure the density or the value of the total mass transported.

It  is also possible to program the system so that after receiving a start signal it measures the total mass transported and signals that a preset mass value has been reached at the digital output.

The  evaluation unit FLOCON 21 is connected to the sensors DR-xxx via a 4-wire RS485 line, whereby the distance between the two units - depending on the quality of the cable used and the interference environment - can be up to 500m. The sensor is also supplied via this line.

This  unit takes care of the calculation of the actual delivery rate, integrates these values ​​into a mass and passes them on via the analog output, thus combining a complete control unit with the functions: parameterization, calibration, status display and data output on a PC interface.
