Bilateral comparison of water flow measurement standards with volume flow-rates from 0.5 m³/h to 40 m³/h and mass flow-rates from 4.36 t/h to 40 t/h

The comparison will consist of two flow meters:

 Meter 1:Meter 2:
Principal:Electro Magnetic Flow:Coriolis mass flow
Make:Krohne AltometerMicro Motion (Emerson Process Management)
Model:Optiflux 5000CMF 200
Serial number:A07 0523914053897
Maximum flow:5 m³/h87.1 t/h - m³/h (*design flow 43.6 t/h - m³/h)
Minimum flow:0.5 m³/h4.36 t/h h - m³/h


Meter 1 will be tested on flow-rates 5, 4, 3, 2, 1 and 0.5 m³/h with 3 repeats except for 4 and 3 m³/h where 10 repeats are made. These flow rates are the flow-rates where the En will be calculated for the comparison. The meter will be provided with in- and outlet pipes that will not be disassembled during the remainder of the comparison.

Meter 2 will be tested on flow-rates 40, 32.7, 21.8, 10.9 and 4.36 t/h - m³/h with 3 repeats except for 32.7 and 21.8 t/h - m³/h where 10 repeats are made. These flow rates are the flow-rates where the En will be calculated for the comparison. No in- and outlet pipes are provided as the principal of the meter does not require this.

All tests will take place at ambient conditions with potable water.
The design flow is the flow rate where the pressure drop over the mass flow meter is about 100000 Pa.
