Abstract
A calibration rig for calibration and/or re-calibration of flow meters (5) and/or flow meter calibration carts (7) is described comprising: a source (1) of pure sterilized water or a source (40) of a sterile conductive solution, a piping manifold (3) connected to the source (1), at least one flow meter (5) connected to the source (1) via the piping manifold (3) and/or at least one flow meter calibration cart (7) connected to the source (1) via the piping manifold (3) and a drain pipe (23) connected to each flow meter (5) and to each flow meter calibration cart (7) to guide liquid from the flow meter (5) and/or the flow meter calibration cart (7) to a drain (23).
Claims3
A calibration rig for calibration and/or re-calibration of flow meters, comprising:
- a source of pure sterilized water;
- a drain;
- at least one flow meter connected to said source and to said drain;
- a calibration reference flow meter installed in one of:
- parallel or series arrangement to said at least one flow meter to be calibrated or re-calibrated;
- and
- a drain pipe connecting said flow meter and said calibration reference flow meter to said drain.
A method of calibration or re-calibration of at least one flow meter on a flow meter calibration rig, the flow meter calibration rig comprising:
- a source of pure sterilized water;
- a calibration reference flow meter;
- and a drain;
- said method comprising the steps of:
- Installing said at least one flow meter to be calibrated or re-calibrated in one of parallel and series arrangement to said calibrated reference flow meter on the calibration rig;
- sending pure sterilized water from the source through the flow meter and the calibrated reference flow meter;
- and
- directing all the water that has been sent through said flow meter and said calibrated reference flow meter to the drain.
