MF 3000

Name: MF 3000
Brand: MUTEC
Availability: InStock

The MF 3000 sensor is installed flush in the pipeline, a welded thread is used for this purpose. The sensor gene- rates a microwave field within the pipeline. Any particle passing reflects the microwaves and causes a change in frequency and amplitude of the reflected signal.

This allows to calculate the speed and quantity of the passing material. Non-moving particles like dust accumulation are not affecting the calculation. The measurement principle of the MF 3000 is unique as the sensor works contact- and maintenance-free and is easy to install and retrofit. Measurement can be very accurate, depending on the bulk material an accuracy of up to 1 % can be achieved. The measurement results are not impacted by changes of temperature, moisture or static charge.

The measurement results are not impacted by changes of temperature, moisture or static charge.

The MF 3000 works with all kind bulk material, with grain size from approx. 1 nm to 20 mm. It can be used in me- tallic pipelines (or metallically shielded pipes and hoses) with a maximum diameter of 300 mm. Depending on pipe diameter a measurement is possible from 1 kg/h to several tons per hour (dilute phase). Constant material velocity, constant bulk density, and a stable di-electrical constant and particle size of the measured material are required. Vibrations and a high buildup of sticky material on the sensor surface should be prevented.

A precise calibration is important to achieve a high mea- surement accuracy. Up to 24 calibration curves can be stored for different materials or conditions. Reference data is captured by weighting the conveyed material, emptying a known quantity and measuring the required time or by deriving the volume information from a theo- retical flow rate of the conveying system. Up to 10 cali- bration points can be saved per curve, at least a min/max calibration with two data points is strongly recommended. The device is equipped with an analog output for the mass flow, a relay for alarm signals, a pulse output for connecting a counter, a RS485 Modbus interface and an USB port.

Installation and Commissioning

The key for an accurate measurement with the MF 3000 is to identify a position in the pipeline where particles are airborne and most evenly distributed. This can be achie- ved best in vertical pneumatic pipelines, freefall appli- cations or – with some limitations – in horizontal pneu- matic pipes. It is important to keep a distance to bends, blowers, valves, tapers and branches. Rods and disc reflectors can be installed in the pipeline to ensure an even distribution of the material.
