In general all ISO9000 certified companies has to recalibrate traceableall flowmeters which are relevant for quality control.
Different methods are available:
• Flowmeter is sent back for recalibration
Long shut down time
• Flowmeter will be compared with a scale
Sample has to be taken and a traceable scale must be available
• Flowmeter will be compared with a volume
Sample has to be taken and an approved tank must be available
• Flowmeter will be compared with a reference

Specification of the mobile rig
We will design the mobile rig according to your application:
• Construction such as piping, material, process connection, devices
•Task i.e. registration, visualisation of the measureing values, pump
control, batching etc.
• Different kind of power supply, compressed air, for hazardous areas
• All devices can be calibrated traceable

Project handling
• After the first customer contact, the customer should decide either one
of the two standards are suitable or he needs a different rig.
• A specification sheet supports to specify the rig.
• The offer will be prepared according to the specification sheet.
• E+H will manage all the sub-suppliers, set up and test the rig.
• Afterwards, the rig will be calibrated in PC Flowtec.
• A witness test can be ordered optionally
