Wet sand can be a challenging material to handle. Its hydrophilic nature encourages caking and clumping, making level management in wet sand bunkers difficult. Wet sand is also abrasive, which can cause wear and tear on measuring devices. Manufacturers using wet sand bunkers need a level management solution that can withstand heavy loads and caking, and is resistant to abrasion.
Capacitance point level detection (-40°F to 932°F / -40°C to 500°C)
Structurally strong and can withstand heavy loads of material above the probe
Handles caking of product on or near probe.
Simple to install and set up with Active Shielding technology
Used for full, demand, or empty tank detection
Capacitance Probe technology explanation, section 3.7 Measuring the level of solid materials
Vibrating Fork Technology (-40°F to 302°F / -40°C to 150°C)
Often mounted towards the top of the bunker for high-level detection
Cost effective option for general point-level measurement

Non-Contacting Radar Technology, section 2.2 Measuring the level of solid materials
The Rosemount 2555 Solids Level Switch is robust and suitable for all solids bulk media in all types of vessels. It can be used for full, demand or empty detection and is designed for low dielectric medias and extreme conditions such as high temperatures, high mechanical stress and high tensile forces.
The Rosemount™ 5408 Non-Contacting Radar Level Transmitter uses enhanced technology and Human Centered Design to deliver accurate, reliable measurements on both liquid and solid materials. Using two-wire FMCW technology the Rosemount 5408 deploys a continuous echo to maximize radar signal strength and produce a more robust and reliable measurement. Delivering ease-of-use at every touch point, the Rosemount 5408 uses an intuitive software interface to guide the operator through installation, commissioning, proof-testing and maintenance. Powerful onboard diagnostics suite proactively monitors transmitter health and alerts if there is an issue. Safety certified to IEC 61508 for SIL 2 applications, the Rosemount 5408:SIS reduces cost of risk, increases efficiency and protects people and the environment.
The Rosemount 2511 Solids Level Switch is suitable for fine-grained and powdered medias, in storage and process vessels. It is a cost effective and robust technology, with high sensitivity and that is easy to operate.
