Magnetic Flow Meters
QTRD91 non-contact radar level meter principle
Ultrasonic Level Meters
Coriolis mass flow meter work as master meter
In Philemon Instrument, we have DN3-DN3000 calibration equipment.
Those equipments could be used to calibrate electromagnetic flow meter, turbine flow meter, ultrasonic flow meter and so on.
Normally, there have two calibration methods. 1. Master meter 2. Weighting method.
To improve the calibration accuracy, my company have updated our master meter from electromagnetic flow meter to coriolis mass flow meter this year.
The accuracy for coriolis mass flow meter is 0.1%.
Then, it could guarantee the calirbration accuracy for electromagnetic flow meter, etc.
