Calibration and Testing

Product code: Calibration

Product Overview

We operate a purpose built flow calibration laboratory, allowing us to realise the highest levels of control and accuracy in flow calibration of variable area / rotameter type flowmeters, fully traceable to National Standards. In this way we are able to ensure that all our products meet the performance requirements of our customers. We are also able to provide an in-house calibration and certification service for flowmeters, fully traceable to National Standards, using our Primary Volumetric or Series Flow calibration facilities.     Please contact us for more information about this service.
