Calibration of flow meters at the highest level

Since 1994, KEM has been performing its own calibration at the highest technical level on its flow meters. The Calibration Laboratory works with a highly accurate weighing system. With an accuracy of 0.05 percent for the weight and 0.1 percent for the volume of liquid fluids, KEM occupies a leading position throughout the world. The German Accreditation Body (DAkkS) has accredited a laboratory with engineers, processes and measuring equipment according to the international standard according to DIN EN ISO / IEC 17025: 2005. Calibration is a professional method for obtaining accurate and usable precision measurement information. Calibration is performed with different hydrocarbons - a unique feature of the KEM calibration stand. This ensures optimal simulation of changing operating conditions in density, direction of flow and viscosity even in temperature changes. Therefore, if viscosity variations occur within a customer-specific application, the predominant viscosity for the use of the flowmeter may be deliberately taken into account.

Even national testing laboratories use calibrated KEM flow meters to make a world-wide comparison of the accuracy of their equipment abroad

In addition to the calibration of its own products, KEM also offers calibration services for various flow meters in Bad Kötzting. Most flowmeters from customers of this service are intended for use in the automotive, pharmaceutical, food, aerospace, biotechnology or general measurement industries. The individual detailed calibration record not only documents the accuracy of the flow meter, but also guarantees traceability to the customer according to national standards.

The advantage for the customer is that all the requirements of the relevant international quality standards are met.
