Calibration Facility

Where accurate flow measurements are required or even critical, it is imperative that the flow meter being used is producing correct and consistent results. Only by calibrating a flow meter can you provide assurance that it is performing accurately and within it’s stated specifications.

We recently commissioned an in-house flow meter calibration facility to offer low cost, flexible calibration services for flow meters of many measuring principles and sizes.

The facility sited in Buckinghamshire consists of three calibration rigs for water, oil and micro flow. The test rigs are UKAS traceable and are currently undergoing the development of quality, admin and technical operations to ISO 17025 with a vision to be certified later this year.

Calibration Rig

Our calibration facility can test flow meters between ¼ and 4 in size and can handle flow rates from 0.001 litres up to 1000 litres per minute. The rigs incorporate highly accurate master meters as reference devices, the water calibration rig for example uses the latest electromagnetic flow meters from Badger Meter that perform to an accuracy of better than ±0.25%.

This new service allows us to offer re-calibrations of existing flow meters that are no longer performing correctly and also provide new flow meters pre-prepared for their application to reduce any inaccurate calibrations being made onsite by customers. The calibration facility will also be used for confirming the accuracy of flow meters, technology demonstrations and staff training.

In addition to the option of in-house calibration, a technician from Bell Flow Systems can also carry out an on-site calibration using proven re-calibration techniques if required. All calibrations are issued with a calibration certificate to ensure that all flow meters calibrated by us offer repeatable, accurate measurement, guaranteed.
