Description

• Size (mm) – Refers to inside bore diameter.
• Max Flow Rate (Q m3/h) – Refers to the emergency flow rate in the event of system failure. Damage may result.
• 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.
• When ordering please state whether for hot or cold use. Suffix Part No. with C (Cold) or H (Hot) and please advise of preferred pulsed output at time of ordering.
• Figures apply to both hot and cold meters.
• Pressure drops on all sizes are generally below 0.2 bar.
