- Abstract:
- A new test set-up for calibration of flow meters used in cooling applications has been established at Danish Technological Institute. The calibration set-up is based on reference metering with a Coriolis type flow meter. It consists of a closed conduit by means of a piping system for circulating a coolant mixture (e.g. 60/40 ethylene glycol/water mixture)in series through the reference flow meter and the meter under test. The coolant mixture is cooled through a pipe-in-pipe exchanger using CO2 as refrigerant.Traceability of the reference flow meter is realized by means of a weighing system, which is also a part of the facility, so that the reference flow meter can be calibrated on a running basis. The facility is designed for a media temperature ranging from -20 °C to 20 °C and a flow range up to 30 m³/h.
