DYNA - Model M-flow -Microwave Technology Bulk Solids Flow Measurement System

SHARE
The DYNA M-flow leverages advanced microwave technology for accurate flow measurement of bulk solids within metallic pipelines. It accommodates flow ranges from a few kilograms per hour to several tons per hour, making it ideal for a variety of industrial applications including powders, dust, pellets, and granulates. The system is engineered for seamless integration with pneumatic conveying and freefall processes, facilitating easy installation and startup. Key features include a contact-less measurement mechanism, adjustable sensitivity, long-term stability, and robust reliability. The DYNA M-flow comprises a sensor probe, a DIN-rail transmitter, a welding branch, and DYNAvisual PC software. The sensor attaches flush to the inside of pipes via a welding branch, suitable for both vertical and horizontal configurations. Connectivity options encompass RS232, RS485, pulse output, error relay, and 4-20mA analogue output. Calibration is performed using DYNAvisual software with one or multiple reference points, and data can be output in analogue or digital form. The system also features a galvanically separated RS485 interface for PLC integration.

Using state-of-the-art microwave technology the flowmeter DYNA M-flow is designed for flow measurement in metallic pipelines from a few kg/h to many t/h. The system is suitable for on-line measurement of powders, dust, pellets, and granulates.

The measurement principle of the DYNA M-flow is based on the physical Doppler-Effect, whereas the sensor generates a uniform field in the microwave frequency range inside the pipeline. These microwaves are being reflected by particles passing through the pipe. Calculation of frequency and amplitude changes allows an accurate determination of the solid's mass flow rate. Nonmoving particles like dust accumulation are excluded from calculations.

The DYNA M-flow consists of a probe, a DIN-rail transmitter, a welding branch and the PC-software DYNAvisual.

The process interface occurs by a welding branch, through which the sensor is screwed flush with the inside of the pipe. With this a flanging at perpendicular and horizontal pipes for free fall and pneumatic conveying occurs.

The probe is connected by a four core cable to a DIN-rail mounted transmitter with 4...20 mA, pulse output, error relay, RS232 and RS485 output.

For commissioning and calibration a notebook with our DYNAvisual software is needed. Calibration can be performed with either one or more reference points.

The measurement value is output either analogue or as digital signal. A serial COM interface is available at the front of the transmitter to connect a notebook computer and a RS485 interface for connection to a PLC system.
