Flow & Volume

The main tasks of the Flow & Volume Laboratory are:

To maintain and develop the national standards for fluid flow and volume.
To maintain the national traceability chain in flow and volume measurements unbroken and linked to the corresponding international standards. This is accomplished by actively participating in the works and inter-laboratory comparisons organized by the European Metrology Association (EURAMET) in the framework of the Mutual Recognition Agreement (MRA).
To provide traceable calibration services to private accredited laboratories or other independent public and private institutions.
To issue calibration certificates for measuring equipment and instruments.
To provide the metrological assessment and verification of instruments subject to the regulations of the Measuring Instruments Directive (MID) whenever this is technically feasible.
To provide support and information to any interested body in issues related to metrology and particularly in flow and volume measurement.
To provide continuing education in metrology and particularly in flow and volume measurement and calibration of such measuring devices.
To be the official advisor of the Greek State in issues related to flow and volume measurements.

Liquid Flow Laboratory

The laboratory of Liquid Flow maintains two primary flow facilities working in the range from 2.5 l/h to 100000 l/h. The realization of the unit of flow is based on the gravimetric and volumetric principle, respectively. Calibration services for all common flow metering devices are provided using water and MIL-C-7024 as calibration fluids. The measurement uncertainty of the two primary flow facilities is better than 0.2%.

Gas Flow Laboratory

The Laboratory of Gas Flow realizes the unit of gas flow in facilities comprising of several commercial primary volumetric flow devices. All gas flow devices are working with clean, dry, compressed air up to 4 bar and upon request pure nitrogen can also be used. The gas flow laboratory provides calibration and testing services for all basic gas flow metering devices in the flow range from 0.5 l/h to 430 l/h and from 1 m³/h to 130 m³/h, respectively, with relative uncertainties better than 0.2%. All primary gas flow facilities are traceable to NMi (The Netherlands) and NIST (USA).

Volume Laboratory

The Laboratory of Volume of EIM maintains facilities for calibrating laboratory glassware, metal volume provers and tanks based on established gravimetric and volume transfer methods.

In particular, calibration services are provided in house for the following categories: vol_Pipette

laboratory glassware and volume standards
Range 5 ml - 20 l Relative
Uncertainty better than 90 ppm

metal volume standards
Range 50 l to 2000 l
Relative Uncertainty better than 200 ppm

proving tanks of capacity > 2000 l
Relative Uncertainty better than 0.2%

All calibration services offered are traceable to the national standards of mass, density and temperature maintained at EIM.
