SolidFlow 2.0 has been specially developed for measuring solid volumes conveyed through pipelines.

SolidFlow 2.0 is used for online measuring:

  • all types of dust, powder, granulates, etc.

  • with particle sizes between 1 nm and 10 mm

  • which are conveyed pneumatically

  • or in free fall after mechanical conveyor systems

Product Description


SolidFlow 2.0 is extremely easy to install and has a wear resistant design.

SolidFlow 2.0 is the latest generation of microwave-based measuring systems for measuring the flow of solids.

Based on our many years of expertise, Envea has developed a second generation version of this sensor.

SolidFlow 2.0 is a reliable sensor which eliminates the disadvantages encountered in current technologies available on the market.


Compounding Plant

Mixtures are created using the sandwich technique with a weighing container.

The existing weighing device was not designed for dosing small quantities of additional components, which meant that measured doses could not be reproduced.

Benefits: SolidFlow 2.0 enables the dosing of additional components to be reproduced and better balancing of the quantities used.

Fuel Delivery

In a boiler, dust is conveyed as fuel to the combustion chamber. As there is no information about the distribution of fuel quantities in the different supply lines, setting optimum combustion is not always possible

Benefits: Each supply line is monitored by a SolidFlow 2.0 system, and the supply of fuel quantities is regulated in each individual supply line.

This enables accurate and uniform distribution of fuel quantities which is an essential requirement for optimum combustion.

Quantity Balancing

The supply of materials to the grinding system is subject to significant fluctuations.

Benefits: With SolidFlow 2.0, the progress of the mass flow can be measured and documented.

If necessary, adjustments can be made. By measuring the coarse grain between the grinding system and the mill, the grinding quality can also be monitored.

• Free-Fall Application

A belt weigher records the amount of cement conveyed. This measurement is used as a guide value when metering the addition of iron(II) sulphate.

This must be metered with a proportion of 0.2 to 0.3 %.

Benefits: With SolidFlow 2.0, the actual value of the metered iron(II) sulphate is recorded and regulated by adjusting the screw conveyor’s speed.

The result is uniform product quality.

• Automatic Salt Dosing System in Food Manufacture

How was the process managed before?

Problem: A sample of product was taken, this needed to be chilled and fragmented before testing. It took 1 hour before a result was given meaning any deviation within the process was not detected straight away. Change was needed because the process was too slow.

Solution: By installing a SolidFlow in-line sensor, a trend of the salt flow has been determined and this is linked to the process control system to give an instantaneous reading. Process parameters have been set within the control system to alarm if the salt flow is either above or below tolerance. This enables the operator to react to changes within the process quicker, to maintain product consistency and quality


  • Visibility of product addition
  • Operator able to make adjustments quicker to maintain product consistency
  • Avoidance of overdosing (cost reduction) or underdosing
  • More consistent finished product
