However, in practice, larger BPRs are typically sized to achieve a good balance between needed precision and economical body sizing. For example, a 3\/4&#8243; BPR might provide a pressure build of 5% at full water flow capacity, whereas a 1&#8243; BPR might have precision in the 2% range. Depending on the accuracy requirements and the user&#8217;s budget, your application engineer can help you size a model to meet all your requirements.<\/span><\/p> <h3><span style=\"color: #333333;\">Precision at Different Pressure Ranges<\/span><\/h3> <p><span style=\"color: #333333;\">Theoretically, it is possible to achieve the same % precision at low pressure setpoints as it is with high pressure setpoints. However, in practice, this is rarely achieved. In order to achieve excellent precision at lower differential pressures, it is necessary to over-size the unit such that the friction from fluid moving through the passages is small relative to the available pressure differential. In ultra-low pressure application, this is rarely achieved due to the economics of supply of very large regulators.<\/span><\/p> ","protected":false},"excerpt":{"rendered":"<p>See Equilibar precision in action: Overview of back pressure regulator technology Contact our engineers to discuss which regulator is appropriate for your application.
