New, specially-designed or existing scales can be upgraded and easily connected to components for automation to make sure that you receive the exact amount of raw material required.

Weightless calibration is a theoretical calibration done without actual test weights.  Read the Weightless Tank Scale Calibration White Paper to learn more.

You can improve your tank scale calibration process by learning about the different methods that are available in the Weightless Tank Scale Calibration White Paper.  All the different options for calibrating your tank scale are explained.

CalFree™ is a combination of equipment functionality, calibration methods and factory quality assurance that enables calibration without test weights.  CalFree is based on factory calibration data of the weighing sensors.

The influences on tank calibration that can be determined are load-cell sensitivity and local gravity variations.

The random influences on tank calibration are how load cells and weigh modules were installed on the tank, how rigid pipes are on the tank.

Weighing is the most accurate measuring technology for critical process tanks and reactors.

Theoretical calibration methods can be used when low traceability is required, like for bulk storage tanks and level control.

Some load cell manufacturers store calibration data in analog load cells calling this method Smart Calibration.  Despite the claims, those methods are low accuracy as they cannot accommodate mechanical effects such as piping.  Furthermore cables, junction boxes, safety barriers and load cell tolerances impact the calibration randomly similar to any other analog load cell system. Thus using the wrong components and unskilled installers can result in significant calibration errors.
