"I have been selling BlueLevel products to concrete plants for years and ALL of my customers have great things to say about them, especially the Model RH rotary paddle bin level indicators. Love those lights!"



BlueLevel Technologies level measurement sensors, level indicators and silo inventory systems help monitor and control production processes within a vast array of industries. Our sensors are critical instruments involved with the automation of manufacturing most everything around us including plastics, resins, chemicals, pharmaceuticals, pipe, brick, blocks and concrete products, to grains, animal feed, food stuffs and ingredients of all kinds, wood products, vinyl siding, shingles, metal products and more.


Take a closer look to see how BlueLevel can help you and your company improve productivity, profitability, reduce expense and simplify your choice of level measurement and monitoring controls.





Concrete is fundamental to our modern day construction and a key part of the global economy. It is everywhere! It is used for roads, sidewalks, houses, bridges, skyscrapers, pipes, dams, canals, missile silos, and nuclear waste containment.


Concrete production incorporates many related aggregate processing industries. These include cement production, sand & gravel, flyash processing and others. All of these industries utilize bin level indicators, level controls and material level sensors to provide a wide variety of functions including high level monitoring to prevent overfilling of bins and silos, low level detection to provide re-order of materials in storage silos and prevent outages and silo inventory monitoring.


Other applications for level indicators and sensors include belt conveyor under/over loading and high level indication of open piles of material under a conveyor discharge. Find out more.



Grain Industries


Grain related industries include grain storage, grain processing, seed processing, feed milling, pet food production, as well as flour milling. Moving grain through storage, processing and production requires the handling of millions of tons of a wide variety of grain each year.


Whether you have a grain elevator, a small local co-op storage facility, a grain processing facility producing oils and other ingredient materials, a mill turning wheat into flour or you’re processing grain and other ingredients to produce domestic and pet animal feed, you need level measurement and monitoring instruments. BlueLevel Technologies products are used throughout these grain related industries.


Grain elevator construction and usage dates back to the mid-1800’s, and in conjunction with the steam powered “marine leg" used to lift grain from barges and ships into land-based storage units, grain elevators revolutionized the distribution of grain products from the farms to market. Bin level indicators are integral components of elevator control and grain processing. Find out more.


In the late 1800’s the first production and milling of feed products for domestic animals began. Corn gluten was originally used as feedstuffs in 1884 and in 1894 the leading global producer of animal feed (Purina) began operation. Bin level indicators are used in numerous areas of the monitoring and control of feed milling operations to improve efficiency and reduce costs. Find out more.





The process of converting raw plastic material into usable products and parts can be accomplished by one of a number of methods, including injection molding, extrusion and blow molding. Most plastics fall into the category of ether thermoplastic or thermosetting. Thermoplastic is a plastic that melts to a liquid when heated. It freezes to a brittle, very glassy state when cooled sufficiently. Most thermoplastics are “high-molecular weight polymers" whose chains associate through weak Van der Waals forces (like polyethylene); stronger dipole-dipole interactions and hydrogen bonding (like nylon); or even stacking of aromatic rings (like polystyrene).


Thermoplastic polymers differ from thermosetting polymers (like Bakelite and vulcanized rubber) as they can, unlike thermosetting polymers, be melted and molded repetitively. Many thermoplastic materials are "addition polymers," e.g. "vinyl chain-growth polymers" such as polyethylene and polypropylene.


The most common thermoplastics are polystyrene (low cost; lacks strength and longevity), ABS (acrylonitrile butadiene styrene) used for a wide variety of parts from plastic toy blocks to electronic enclosures, polyamide (chemically resistant, heat resistant, tough and flexible; used for combs), polypropylene (tough and flexible; used for containers), polyethylene and polyvinylchloride PVC (more commonly used in extrusion of parts rather than injection molding).


The main differences between thermoplastic and thermosetting plastics is that thermoplastics become soft, re-moldable and re-weldable when heat is added. Thermosetting plastics, however, when heat is added will chemically decompose so they cannot be welded or molded. On the other hand, once a thermosetting is cured it tends to be stronger than a thermoplastic.


Whatever the process, the use of level measurement and automatic level control, or bin level indicators, is critical in order to ensure productive and profitable operations. Common uses of level measurement and monitoring instruments within the plastics industry are in the material storage and manufacturing process. These uses include high and low level monitoring in raw material silos, bins and machine hoppers. Find out more.





Process industries include Power Generation, Chemical, Food, Pharmaceutical and Biofuel processing. In all of these Process industries, high-value materials often will move through processing with continuous flow, without bottlenecks. In addition, batch processing must produce end products using ingredients and other materials that are stored and processed within a variety of tanks, bins and other types of vessels. The material processed and ingredient components can be liquids, powders and granular bulk materials. Level measurement and control can affect productivity and profitability within your process.


Looking a little closer at one of these process industries we find that Power generation includes coal fired power generating stations. This is one of three types of fossil fuel based power generating facilities. A coal fired plant converts coal into thermal energy and then to electricity. Point level and continuous level measurement sensors are used in many applications within coal fired plants, and many different technologies may be used. Find out more.
