Hopper & Tank Scale Calibration for Accurate Batching in Manufacturing

We calibrate and repair hopper, tank, and mixer scales for manufacturing, ensuring accuracy for batching, compliance, and quality control audits

Accurate Weighing is Critical for Specialty Manufacturing

In industries like food processing, chemical production, and specialty manufacturing, precision is everything. Tanks, hoppers, and mixers are often suspended on load cells that must be properly calibrated to ensure accurate batching and blending.

At Peninsula Scale, we have the tools, expertise, and certified test weights to calibrate and repair these integrated weighing systems — even on short notice.

The Challenge: Urgent Calibration Before an SQF Audit

A candy manufacturer contacted us when they couldn’t get their usual supplier to perform calibrations in time for an upcoming SQF (Safe Quality Food) audit.

Most of their weighing devices — like a Doran 2200 bench scale used for measuring corn syrup in small batches — were straightforward. But their custom-built mixing area required specialized calibration techniques.


Specialized Calibration for Hopper & Tank Scales

Large ingredient hoppers often lack a flat platform for traditional weight placement. To address this, we used specialty weight-hanging hardware that attaches to either side of the mixing vessel.

This setup allowed us to:

  • Hang multiple NIST Certified 50 lb grip-handle calibration weights directly onto the hopper


  • Evenly distribute loads across all load cells for accuracy


Test individual load sensors to diagnose potential issues


Why Load More Weight for Calibration?

The manufacturer’s previous service provider was only inspecting the hopper with 100 lbs of certified test weights. We were able to test with 500 lbs of certified weights, which greatly improves calibration accuracy — especially for high-capacity batching systems.

Automation Integration

This hopper system used an Avery Weigh-Tronix ZM405 digital weight display with a setpoint control to automatically stop the filling pump once the target weight was reached.

Peninsula Scale can provide:

  • Custom programming for digital weight indicators
  • Automated batching controls
  • Process improvements to reduce labor and eliminate costly errors
