Mass flow measurements of dry bulk goods with the Envea MaxxFlow HTC

The Envea MaxxFlow is an inline mass flow meter specially developed for measuring the mass flow of dry bulk goods without influencing the flow. This article discusses some applications of the MaxxFlow.

The open construction and compact form, combined with a very high throughput capacity, make the MaxxFlow usable in situations where previously only complex mechanical systems such as weigh hoppers or impact flow meters were applicable. The MaxxFlow can be easily calibrated and sends measurement data directly to the control system.

The advantages of the MaxxFlow over an impact flow meter »

The electromagnetic flow meter works contactlessly and is completely dust-proof and erosion-free due to the ceramic interior of the pipe. As a result, the MaxxFlow is virtually maintenance-free and has a long lifespan.

The MaxxFlow can be installed in various ways:

  • Vertically:

Application: Mass Flow

A cement manufacturer mixes three materials in a screw mixer: cement, ash, and filter powder. To ensure accurate dosing of the materials, the quantities at the discharge of the silos must be measured. These measurements are used as a reference parameter for the dosing of additives. For this application, each silo needs its own system to measure material discharge. The dosing of the material discharge is controlled via a slide valve.


The MaxxFlow HTC is used to measure the material flow from the silos. This application involved a material flow of 70 t/h of cement, 30 t/h of ash, and 20 t/h of filter powder from three different silos.

Advantages for the customer:

  • Precise control of material flow
  • Simple and quick calibration
  • No installation in the flow
  • Robust and a long lifespan
