In our lab we can calibrate liquid flow Controllers and liquid flow meters.
As calibration medium you can choose between water en Iso-propanol depending on your process liquid.
The reference standards used are primary, meaning calibration takes place by comparison of flow vs weight. The weight is measured by use of weight balances traceable to national standards (Kg).
Minimum flow range is 4 grams per hour up to a maximum of 1800 kg per hour.
