Low Profile Disk Load Cells for Precise Raw Material Feeding in Chemical Storage Tanks
In the chemical industry, accuracy is not just a technical requirement — it is a foundation for safety, product quality, and cost control. Whether producing resins, coatings, detergents, polymers, or specialty chemicals, manufacturers rely on precise control of raw material feeding to ensure consistent results. Even a small deviation in material input, repeated over hundreds of batches, can lead to wasted materials, unstable reactions, or costly rework.
This is why tank weighing systems based on Low Profile Disk Load Cells have become a preferred solution for raw material dosing and inventory control in chemical storage tanks.

Why Weighing Is Critical for Raw Material Feeding
Many chemical plants still use level sensors or flow meters to estimate material input. While these methods can work in simple applications, they often struggle in real chemical environments:
- Changes in material density
- Temperature fluctuations
- Foam formation
- Viscous or sticky liquids
- Powder bridging and buildup
Weighing, by contrast, measures the actual mass of material inside the tank. It is independent of material properties and provides a direct, reliable signal for process control systems.
For raw material feeding, weighing allows operators to:
- Control dosing with high precision
- Automate batch recipes
- Monitor consumption in real time
- Prevent overfilling or material shortages
- Improve batch-to-batch consistency

Why Low Profile Disk Load Cells Are Ideal for Chemical Storage Tanks
Among different load cell types, Low Profile Disk Load Cells are especially well suited for chemical tank applications.
Low Installation Height for Existing Tanks
Chemical plants often operate with limited space under tanks. In retrofit projects, raising a tank by even a few centimeters can mean modifying piping, platforms, or support structures.
Low Profile Disk Load Cells are designed with an extremely compact height. They can be installed under tank legs or support points with minimal changes to the existing structure, making them ideal for both new installations and plant upgrades.
High Load Capacity with Excellent Stability
Chemical storage tanks are heavy, especially when filled with liquid raw materials. Disk load cells work in pure compression, allowing them to handle high loads ranging from several tons to tens of tons with excellent long-term stability.
Their solid, symmetrical design ensures:
- Uniform force distribution
- High repeatability
- Minimal signal drift over time
This stability is essential for precise feeding control in continuous or batch production.

Resistance to Side Forces and Thermal Expansion
In real chemical plants, tanks are rarely “free-standing.” They are connected to:
- Inlet and outlet pipes
- Agitators
- Heating or cooling jackets
These connections introduce side forces and constraints caused by temperature changes and mechanical movement. Low Profile Disk Load Cells, especially when used with proper mounting hardware and limiters, are more tolerant of these influences than many traditional beam-type load cells.
This results in:
- More reliable weight readings
- Fewer calibration issues
- Reduced maintenance over the system’s lifetime

Built for Harsh Chemical Environments
Chemical production environments are demanding. Humidity, corrosive vapors, dust, and aggressive cleaning procedures are common.
Low Profile Disk Load Cells used in chemical tank weighing systems are typically designed with:
- Stainless steel construction
- Hermetically sealed strain gauges
- IP68 or IP69K protection ratings
This makes them suitable for long-term operation in acidic, alkaline, or solvent-rich environments without compromising performance.
Precise Raw Material Feeding: How the System Works
A typical chemical storage tank weighing system for raw material feeding includes:
- 3 or 4 Low Profile Disk Load Cells installed under the tank
- A junction box for signal summation
- A weighing indicator or transmitter
- Integration with PLC or DCS control systems
As raw material is added to the tank, the load cells continuously measure the increase in weight. The control system compares this data with the target value defined in the recipe and automatically stops feeding once the required amount is reached.
This closed-loop control enables:
- Accurate dosing down to very small tolerances
- Fully automated material feeding
- Reduced operator dependency
- Improved production efficiency
Applications in the Chemical Industry
Low Profile Disk Load Cells are widely used in various chemical tank applications, including:
Raw Material Storage Tanks
For solvents, liquid additives, plasticizers, and other base materials, accurate weight measurement ensures precise feeding into downstream processes.
Reactor and Mixing Vessels
During batch production, load cells allow operators to monitor each ingredient added to the reactor, ensuring the correct sequence and quantity.
Intermediate and Buffer Tanks
Weighing provides real-time inventory data and helps coordinate material transfer between production stages.
Specialty and Fine Chemical Production
In high-value products, even small dosing errors can have a significant financial impact. Load-cell-based weighing offers the precision required for these processes.
Benefits Beyond Accuracy
While precision is the primary goal, chemical manufacturers also benefit in other ways:
- Reduced raw material waste
- Improved product consistency
- Better process traceability
- Lower maintenance costs compared to alternative measurement methods
- Easier compliance with quality and safety standards
Over time, these benefits translate into measurable cost savings and more reliable production.
A Proven Solution for Modern Chemical Plants
As chemical production becomes more automated and quality-driven, reliable measurement systems are no longer optional. Low Profile Disk Load Cells provide a robust, accurate, and practical solution for chemical storage tank weighing and raw material feeding control.
Their compact design, high load capacity, resistance to harsh environments, and long-term stability make them a trusted choice for chemical manufacturers worldwide.
For plants looking to improve dosing accuracy, reduce waste, and gain better control over their production processes, tank weighing systems based on Low Profile Disk Load Cells are a proven and future-ready investment.
