Prop Configurations

APPLICATIONS —
Sparling propeller meters have been developed for "clean" water applications where the temperature of the water does not exceed 100°F and suspended solids do not exceed 0.5%.

INSTALLATION —
Meters must be installed in full flowing suction or discharge lines. Avoid valves, fittings or obstructions immediately upstream of the meter. These may cause jetting or uneven flow profiles. It is recommended that a minimum of five straight pipe diameters be maintained upstream and one diameter downstream of the meter.

FLOW —
The maximum flow ranges can be safely exceeded by 50% when used intermittently. When continuous flow rates exceed twice the minimum standard flow rate, high velocity construction is required. Specially configured propellers and rubber bearings are used for long life. Anticipated flow ranges and minimum and normal flow rates expected should always be specified on application sheets accompanying your order for proper evaluation of meter construction.
