Calculate using actual service conditions. **Lower limit of flow range is dependent on user֒s operating density. > Note: Performance enhancement techniques are routinely applied to produce wider linear and useable flow ranges. This technique is also used to improve linearity and repeatability. Consult the applications group at Hoffer with your requirements. >
