RMI provides consultation services, can source and supply instruments for installation by others and can design and supply fully fabricated analyser systems together with training and commissioning services.
When to use RMI:
There are many process measurements that may be routine but some measurements do require specialist skills if they are to deliver optimum performance.
RMI specialises in applications or processes where the demands of the measurement or the application justify consultancy or custom designed solutions.
Typically the systems most commonly supplied by RMI are those based on density or viscosity measurement.
What to measure?
It is important to note that density or viscosity may be used for direct measurements or indirect measurements.
A direct measurement is where the measured property is the property of primary interest.
An indirect measurement is where the property measured is not of primary interest but it is measured because it is an indicator of some other property that cannot be so easily measured.
For example, when controlling the solids content of a slurry it is the solids content that is important, not the density. Yet solids content can be determined by measuring the density and then calculating the percent mass of solids from this measured value.
A typical example is evaporator control: solids content is not easy to determine directly but a range of different properties can be measured all of which bear some relationship to the solids content. Thus for an evaporator, solids measurement may be determined using a choice of different indicator measurements such as Ultrasonic sensors, Vibrating element density sensors, vibrating element or rotational viscometers or refractive index instruments, for example.
The choice must be made based on a variety of factors.
For example, a malt evaporator may result in a product stream where the density varies significantly with solids content simply because the density of the solid material is significantly different to the density of the carrier medium and thus density measurement will resolve the solids content very accurately . On the other hand, in a fish oil evaporator, the density may not change significantly with solids content but viscosity does and in this case the viscosity measurement is the most appropriate for control.
The “Systems” tab in the menu will lead to a variety of different systems discussed to illustrate how seemingly similar applications may require completely different solutions.
This link discuses the basic density and viscosity sensors commonly utilised by RMI. Where the application requires it, alternative technologies will be carefully chosen.
The “Applications” tab in the menu will show a variety of applications where density or viscosity measurements are used. In this section the applications discussed will not include those used in the marine industry, because of the significance of density and viscosity measurements in the marine industry these applications are discussed in their own section, INtegrity.
