Overview

Traditional mechanical flowmeters, such as turbines and PD meters, are usually calibrated in the field when the product properties change. The main reason is that product viscosity directly affects the measurement error of these mechanical flowmeters. To eliminate this viscosity dependency, mechanical meters are usually calibrated on the actual product and operational flow rate using an on-site ball prover.

KROHNE Ball provers come fully equipped, including third party certification and training, and are used by many major oil companies and calibration providers. Ball provers are supplied as standalone systems or can be fully integrated into the metering system. Using a low-friction baked phenolic lining and a proprietary design of micro set sphere detector assures best-in-class prover performance with excellent chemical and abrasion resistance. KROHNE has been providing ball provers since more than 35 years. Modern flowmeters that have no moving parts do not have the same viscosity dependency as mechanical meters. Nevertheless specifications could still call for on-site proving. In this case a combination of KROHNE ultrasonic or Coriolis flowmeters can be provided, in combination with a ball prover.
