Installation guidance

• Install vertically with the inlet below the outlet.
• Use fittings and sealing methods compatible with the 1-inch NPT female thread.
• Support adjoining pipework so that no mechanical load is transferred to the meter body.
• Open valves gradually to avoid pressure shock and sudden float impact.
• Confirm material and seal compatibility before use with liquids other than clean water.

Selection guidance

This meter is calibrated for water. Select a range that places normal operation within the middle section of the scale. Fluid density and viscosity can affect readings with other liquids.
