Flow Meter Calibration


Flow meters offer an important measure of fluid quantities in equipment ranging from gasoline pumps to food and beverage production machinery. When products or materials are valued based on gas or fluid quantity, it’s important to have a calibrated flow meter, as they often act as a cash register for your operation.

Cross is your one stop shop for a range of flow meter calibration services. We offer in-lab ISO 17025 accredited calibration of mass flow controllers and mass flow meters using our Fluke Molbloc system with NIST traceable master testing standards. Additionally, our liquid flow meter calibration partners procedures utilize either gravimetric flow methods, or direct comparison methods with our certified variable area flow meters.

Our experienced technicians report all NIST traceable data on a calibration certificate which is then available 24/7 within GageSuite®, our cloud based calibration management system.
