Hope those technical people out there can help;
We have large process tanks (15,000L) capacity, which have load cells and display. We calibrated the load cells/display by filling tank with calibrated flow meter. The problem is it takes a lot of time and water to fill these tanks.
We have gotten a company in to do a ‘forced calibrations’ by applying pressure/weight to the actual load cells, which they read off their own calibrated test rig.
as an experiment we carried out a forced calibration and then ‘checked’ it with the normal calibration with flow meter, thinking there would be no error, seeing as the forced calibration had a higher accuracy.
Does anyone have any thoughts on this? the forced calibration was supposed to have an accuracy of approx 0.1% and the normal flowmeter method approx 0.3%
thanks and regards
