About Solids Measurement
With Emerson™ you get accurate and cost effective solids measurement with minimum maintenance and easy installation.

Measuring the level of solids can be a challenge. Due to the material properties, solids surfaces are usually uneven with irregular shapes, and there are usually high levels of dust. Along with these challenges, solid materials often have low dielectric constants making them hard to measure.
The Rosemount™ range of solids measurement devices is designed to suit your application. We offer different types of level sensors to make sure you get the perfect fit for your application.
The main benefit of a continuous level measurement is that it can be used to control a process or ensure material availability. Having a continuous insight into the process enables process optimization, reduced interruptions and a higher level of safety.
In level measurement there are often relatively fast level changes and low dielectrics. Radar devices are generally very good at handling this and are therefore recommended for level control and inventory management.
Solids level switches consists of several technologies that are suitable for full, demand or empty detection for all bulk media in all types of vessel.
They are simple to use and install, robust and reliable, insensitive to dust, electrical charge and adhesion. They can be used for simple process control, or handle extreme conditions such as high temperatures, pressure, mechanical stress and tensile forces.
To ensure a safe process, multiple devices can be installed in a vertical, horizontal or oblique position.
All level measurement instruments are affected by the uneven surfaces in solids applications. The material characteristics and silo size will affect the structure of the surfaces, which affects the preferred installation location and choice of technology.
Best practice is to have both continuous and point level measurement instrumentation to ensure a safe and reliable operation.
There is often a considerable amount of dust created during the fill cycle of solid materials.
Both radar and level switches can handle dust in the vapor space without being disturbed. Other technologies such as ultrasonic and laser devices are less suitable since their signal is significantly impacted by dust.
It is important to consider where in the silo the level will be changing, depending on the material characteristics, silo size and filling location. The closer the device is mounted to the filling point, the larger the risk of measurement interference.
Radar instruments are top down installations, while point level switches are mounted in a vertical, horizontal or oblique position. To ensure a safe and reliable operation, multiple devices on different locations are recommended.
No technology is perfect for all applications and the choice of technology is most often application dependent.
Non-contacting radar is an all-around technology for use in a large variety of applications. Guided wave radar is suited for low DC, long ranges and when installation area is restricted. Switches consists of several technologies that are suitable for full, demand or empty detection for all bulk media in all types of vessel.
