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
Vibrating Fork Technology, Section 3.5 Measuring the level of solid materials
Non-Contacting Radar (-67°F to 392°F / -55°C to 200°C)
Continuous level measurement
Eliminate abrasion concerns and can handle dusty environments
Parabolic antennas work well for extended ranges over 50 ft.
Process seals and cone antennas available for small/short bunkers
