RGI 德国Real Good Idea 流量计 Flocon21
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.
