Tank and Silo Weighing

ROUTINE MAINTENANCE & EMERGENCY REPAIRS

Accurate measurement is the backbone of any operation that relies on stored materials—whether liquids, powders, grains, chemicals, or aggregates. Tanks and silos equipped with level sensors or weighing systems provide critical data that influences production, safety, inventory management, and compliance. But like all measurement instruments, these systems drift over time and require scheduled servicing and calibration to maintain performance.

Regular servicing, maintenance and calibration of your tank and silo weighing solutions is important for the following reasons:

  • Ensuring Measurement Accuracy
  • Improving Safety and Reducing Risks​
  • Protecting Equipment Investments
  • Meeting Compliance and Audit Requirements
  • Preventative Maintenance minimises the risks of Breakdowns

What Happens During the Servicing and Calibration Process?

The process varies depending on the system type – hydrostatic, radar, ultrasonic, load cell, or strain gauge – but typically includes the following steps.

PRE-SERVICE INSPECTION

Technicians begin with an evaluation of:

  • System wiring and grounding
  • Mechanical integrity of mounting brackets, load cells, and sensors
  • Environmental conditions (dust, vibration, moisture, temperature)
  • Previous calibration performance

This identifies potential issues before calibration begins.

MECHANICAL & ELECTRICAL CHECKS

A thorough inspection ensures that external factors won’t influence accuracy:

  • Checking for debris, buildup, or product bridging inside silos
  • Verifying load cell alignment and checking for mechanical binding
  • Inspecting junction boxes, cables, and moisture seals
  • Confirming proper sensor installation angles and clear measurement paths

These steps ensure that calibration results are meaningful and stable.

ZERO & SPAN CALIBRATION

The core of the calibration process includes:

Zero Calibration

For weighing systems, this means removing the load (or simulating an empty vessel) to set the system’s baseline reading.

Span Calibration

Calibrators apply known weights, test loads, or simulation tools to adjust the system’s full scale accuracy.

For level sensors, technicians may:

  • Use reference distances or known liquid levels
  • Simulate electronic signals from certified equipment
  • Validate echo profiles for radar and ultrasonic systems

FUNCTIONAL TESTING

Once calibrated, technicians test:

  • Alarms and interlocks
  • Analog and digital communication outputs (4–20 mA, Modbus, Profibus, Ethernet, etc.)
  • SCADA or PLC integration
  • Redundancy or fail safe functions

This ensures every part of the measurement chain operates flawlessly.

Tank and Silo Weighing Servicing & Calibration

Servicing and calibration of tank level and silo weighing systems are essential for ensuring accuracy, safety, compliance, and efficiency. These systems are critical infrastructure in many industries, and proper maintenance not only protects your assets but also contributes to smoother operations and better decision‑making.

A structured maintenance program helps organisations avoid costly downtime, maintain consistent product quality, and stay compliant with industry standards—making it an investment that continually pays for itself.
