MaxxFlow HTC

Medición no invasiva y sin mantenimiento para altos caudales másicos de sólidos, independientemente de la ruta de la tubería

Sensor electromagnético para medir caudales de sólidos de 10…300 t/h.
Sin piezas mecánicas en el flujo de material. 100% resistente al polvo y al desgaste gracias a la vejiga de cerámica.

  • Instalación en bajantes verticales o inclinados
  • altura de instalación reducida
  • calibración sencilla

Medición de caudal desde 10 t/h hasta 300 t/h

  • 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
  • Maximum temperature, 12O °C
  • 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
– For flow rates up to 300 t/h
– Low installation height
– Suitable in situations in which it was previously only possible to use complicated, inaccurate or expensive mechanical solutions (impact plates, measuring chutes)

Installation independently of direction of line (vertical, inclined), but always after mechanical conveyor elements, in various industries:

  • Cement
  • Chemistry
  • Energy
  • Coal plant
  • Food
  • Minerals
  • Lime plant
  • Gypsum
  • Mass-flow measurement of raw meal
  • Mass-flow measurement of potato starch in free fall prefiding chain conveyors
  • Mass-flow measurement of salt in free fall pre feeding chain conveyor
  • Mass-flow measurement of wood pellets in free fall
  • Flow mettering of grains

The MaxxFlow HTC is specially developed for the flow measurement of dry bulk solids during high-volume throughput. Due to its completely open profile and its low installation height, the MaxxFlow HTC is especially suitable in situation in which it was previously only possible to use complicated or expensive mechanical solutions, e. g. impact plates or measuring chutes.

The installation of the MaxxFlow HTC takes place independently of the direction of the line (vertical/inclined), but always after mechanical conveyor elements,
e. g. rotary feeder, screw conveyors, air slides or chain conveyors.

A complete measuring station consists of these components:

• Measuring feeder for installation in the conveyor line
• Transmitter

The measuring feeder is available in sizes DN 100, DN 150 mm and DN 200 mm.
On request the components inlet path (between conveyor element and sensor) and gate valve (for calibration) can also be configured and supplied.

The transmitter is connected to the sensor using 4-wired, shielded cable.
The maximum distance between measuring feeder and transmitter is 300 m.
