What is the role of level control systems in managing dry bulk products?

Level control for dry products provides accurate monitoring of material levels in bins, silos, and hoppers to make sure of efficient operations and minimize waste. Versatile devices, including rotary paddle switches, vibrating rods, capacitance probes, and radar sensors, cater to different applications and are built to withstand harsh environments, providing long-lasting performance. These devices feature user-friendly designs for quick integration, reducing downtime and installation costs. Advanced sensors ensure precise level measurement, maintaining optimal inventory levels, while low maintenance requirements save time and operational costs.


What Devices Are Common for Dry Bulk Level Control?

Common devices for dry bulk level control include:


  • Rotary Paddle Switches: Detect bulk materials by halting rotation when the material reaches the paddle.
  • Vibrating Rod Sensors: Detect material presence by using vibration and are suitable for various bulk materials.
  • Capacitance Probes: Measure changes in capacitance caused by material presence.
  • Radar Sensors: Provide non-contact, continuous level measurement, making them ideal for dusty environments.


What are the Benefits of Advanced Level Control Solutions?

The benefits of advanced level control solutions include:


  • Enhanced operational efficiency, optimizing production processes, reducing downtime, and increasing output.
  • Cost savings by preventing overfilling and material shortages, all while reducing waste and operational costs.
  • Reliable level measurement for safe storage and handling of materials, preventing spills and accidents.
  • Real-time monitoring to help maintain optimal inventory levels, improving supply chain efficiency.
Level Control
Level Control

Level control is essential for many industrial and commercial applications, ranging from simple water tanks to complex chemical processing systems. Industrial applications often require control to maintain safe and efficient operations. This can be accomplished through the use of float switches or differential pressure control. Float switches are devices used to measure the level of a liquid in a tank. They work by using a float that is attached to a switch. When the float rises or falls with the level of the liquid, the switch is activated. This can then be used to trigger an alarm or shut off a pump. Differential pressure control is another level control method that uses pressure sensors to measure the difference in pressure between two points. This can be used to determine the liquid level in a tank. Differential pressure control is often used in applications requiring precise level control. At Centro, we carry a complete selection of level-control products to meet your needs. Our float switches are ideal for small-scale applications, while our radar and differential pressure control systems are designed for more demanding environments. We also offer load cells for use in weight-based level measurement. Whether you need a simple float switch or a sophisticated differential pressure system, Centro has your level control products.

Bulk Solids
Bulk Solids

Bulk solids refer to dry, granular, or powdered materials handled in large volumes across industries like agriculture, mining, food processing, and chemical manufacturing. Managing these materials efficiently requires specialized equipment for conveying, storage, feeding, and processing to ensure flow consistency, prevent blockages, and maintain product quality.

Level Switches
Level Switches

Level switches are used to detect and control the level of liquids that trigger alerts or activate pumps and valves based on predetermined levels to prevent overflows or shortages. Level switches are used in industries such as water treatment, chemical processing, and food production, for efficient process control and preventing environmental hazards.Browse our selection below or contact us to speak to a product expert.

The LMR120006 4-vane Nylon paddle is the standard paddle for the Mini Roto-Bin-Dicator® in most dry bulk applications. Injection-molded Nylon provides excellent impact resistance, chemical resistance to most industrial dusts, and a long service life. The 4-vane geometry is optimized for the Mini Roto's smaller form factor and adjustable sensitivity range of 5–65 lb/ft³.

The LMR120027 insertable food-grade paddle is manufactured from polysulfone, an FDA-acceptable material suited to direct contact with food products, nutraceuticals, and pharmaceutical powders. The insertable design allows installation through the Mini Roto's standard 3/4" NPT process connection without special tools. This paddle maintains the Mini Roto's full 5–65 lb/ft³ density range while meeting the hygiene requirements of food and pharmaceutical processing facilities.

The Pulse Point II (LPII) is a compact capacitance probe point level switch designed for dry bulk powders and granules. It detects material presence or absence at the probe tip by sensing the change in capacitance when material contacts the probe. The LPII-SG variant is a straight single-point probe with a SPDT relay output. It requires simple single-point calibration with the probe in free air. Ideal for materials that are challenging for mechanical paddle switches (very fine powders, high-speed fill applications) or where a flush-mount, probe-style sensor is preferred.

The Mini Roto-Bin-Dicator® packs the reliability of the full-size Roto-Bin-Dicator® into a compact, lightweight injection-molded Minlon® housing sized for small bins, hoppers, and spaces where standard equipment won't fit. The adjustable sensitivity feature allows a single unit to be used across a wide range of material densities, from very light powders at 5 lb/ft³ up to denser granules at 65 lb/ft³, without changing paddles or hardware. The unit can be mounted horizontally for side mounting or vertically for top mounting, and serves equally well as a high, intermediate, or low level indicator. LED status indication provides at-a-glance operational status without opening the enclosure.
