Mobile Flow Rig Calibration

Our on-site flow meter calibration service utilises mobile flow rigs capable of testing a wide range of flow meters. 

The flow calibration rig uses two Calibrated reference Coriolis meters, calibrated by ABB in a ISO17025 accredited facility. These meters are used as a direct reference to compare the test meter against.

The rig uses a recirculation method of calibration. The desired flowrate(s) will be inputted into the control panel the pump will then be set, by way of a VFD, to match this flowrate after the flow has stabilized the test will start. The pulse output is fed back to the control panel where after the run time has been reached with compare the ref and indicated flowrate and produce an error figure.

Flowrates 

• 1,000 kg/h to 65,000 kg/h

Flowmeters tested  

• Flow technology: All main flow technologies
• Sizes: DN15 to DN100
• *DN100 depending on flow range and weight*
• Process connections: Rig can be adapted to the process connection on the test meter
• Outputs: Pulse, frequency and mA can be tested.
• *If digital communications then device will be tested totaliser vs totaliser*
