Nominal Flow Rate (QN m3/h) – Typical application for every day usage.
Transitional Flow Rate (L/hr) – Point at which the flow rate is high enough to achieve a level of accurate measurement.
Minimum Flow Rate (L/hr) – The absolute minimum flow required for the unit to function.
EEC Approved Class – The EEC Classification system used to measure accuracy at very low flow rates.
Standard ISO4064/BS5728/EEC Specification Class B applies.
Bolt Circle Centres – Refers to distance between opposite bolt holes on the flange, taken centre to centre.
