Calibration

Purpose of Flowmeter Calibration
Calibration refers to the act of evaluating and adjusting the precision and accuracy of measurement equipment.
Instrument calibration is intended to eliminate or reduce bias in an instrument's readings over a range for all continuous values.
Calibration is required in accordance to the frequency of use, durability, and the environment after certain period of time.
Top priority of flowmeters are accuracy and performance
Allows manufacturer to procure suitability of various regulations and law.
Procedure
As an International Calibration Laboratory as KOLAS certified,
Weighting System for Standard Liquid Flow facility is available.
The maximum flow is 450㎥ per hour, and could calibrate up to 300mm pipe.
Facility Environment
Calibration laboratory always maintains clean environment.
Pressure gauge, thermometer, hygrometer are used to keep record of calibration environment.
Correction is progressed after equilibrium temperature.
