CPA Range Extender
Brand: Canada Pipeline AccessoriesCPA Sonic Nozzles can be used as a range extender for pressure control valves and volumetric flow meters.
The sonic nozzle introduces a pressure drop downstream, which increases the pressure in the meter tube. This allows the flow meter operating range to be extended by moving a larger standard volume of fluid. Because of this, the meter station capital costs can be decreased by downsizing the flow meter and pipe sizes, without compromising flow limits.
Smaller meters with higher velocities, using pipe reducers as a pre-flow conditioning element, give more accuracy by increasing flow conditioner effectiveness.
Features- The density of the flow in the meter tube is increased, allowing the flow meter to move a larger standard volume of fluid and extend its operating range.
- Reduce the meter station capital cost by downsizing the flow meters and pipe sizes without compromising flow limits.
- Smaller meters with higher velocities allow for lower uncertainty by increasing flow conditioner effectiveness and using a pipe reducer as a pre-flow conditioning element.
- For redundant measurement, differential pressure can be taken across the flow conditioner, flow meter, flow nozzle, and a combination of these elements or the entire meter tube.
- Reduce or eliminate control valve noise by moving a problematic pressure drop location away from a control valve, and allowing the sonic nozzle to take the pressure drop.
