MaxxFlow HTC Electromagnetic Flow Meter Measurement for Dry Bulk Solids

MaxxFlow HTC Electromagnetic Flowmeter is designed for the measurement of high mass flow rates for dry bulk solids from the exit of pre-feeding devices, e. g. screw conveyors, air slides, rotary valves, bucket elevators, etc.

• Most non-metallic solids can be measured
• Can be installed on round pipes or ducts
• No real upper limit of mass flow
• Maximum pressure 10 bar
• Dust tight
• No flow restrictions to the process flow (wear-resistant ceramic liner)
• The mass flow measurement is independent of flow characteristics
• Can be installed at an angle
• Small footprint, 220 mm (DN 100), 290 mm (DN 150), 310 mm (DN 200)
• No moving parts, hence no maintenance
• Easy to calibrate
• Installation free of obstacles in the cross-section, therefore no dead spots
• Independent of the arrangement of the line(vertical or inclined)
• Easy retrofitting
• Non-contact measurement procedure (no mechanics)
• Maximum material temperature 120 °C
• abrasion–resistant ceramic inner tube
• maintenance-free
• System accuracy: 0.04 %

System

A complete measuring point consists of these components:

• Sensor for installation in the conveyor line
• Evaluation Unit MSE 300

The sensor is available in sizes DN 70 mm, DN 100 mm, DN 150 mm, and DN 200 mm.

With the design in DN 70 mm, the connection flange could be freely selected.

The evaluation unit, in Field housing or DinRail version, is connected to the sensor using a 4-wired, shielded cable.

The maximum distance between the sensor and the evaluation unit is 300 m.
