Lenox Laser has been a pioneer and a leader in the critical flow orifice field for over 20 years. Customers have had orifices custom sized, drilled, and calibrated for them in various flow components in order to meet complicated and critical needs. We are able to eliminate the need for expensive and complicated mass flow controllers with our easy to use, inline, consistent, and cost-effective orifice technologies. A Lenox Laser calibrated orifice will produce consistent and repeatable flow rates of gas and liquids time and time again.
Lenox Laser has also created easy to use Orifice Sizing Calculator which has aided thousands of customers determine their orifice size for their flow control application. The calculator uses our flow control mathematics formulas which can be found in detail here. Our free online calculator can determine an orifice size using the following input values:
Inlet Pressure - PSIA, PSIG, Inches Mercury Absolute, Inches Water Absolute, Barr, Torr, Atmosphere, Kilopascals
Outlet Pressure - PSIA, PSIG, Inches Mercury Absolute, Inches Water Absolute, Barr, Torr, Atmosphere, Kilopascals
Gas Type - Air, Acetylene, Ammonia, Argon, Carbon Dioxide, Carbon Monoxide, Ethylene, Helium, Hexahydrochloride, Hydrochloric Acid, Hydrogen, Methane, Methyl Chloride, Nitrogen, Nitric Oxide, Nitrous Oxide, Oxygen, Sulfur Dioxide
Temperature - Fahrenheit, Celsius, Kelvin
Flow Rate - std cubic cm/sec, std cubic cm/min, std cubic cm/hr, std cubic ft/sec, std cubic ft/min, std cubic ft/hr, std gal/sec, std gal/min, std gal/hr, std liters/sec, std liters/min, std liters/hr, std pounds/sec, std pounds/min, std pounds/hr, std grams/sec, std grams/min, std grams/hr
Hole Units - Microns, Inches
The calculator will then display the appropriate hole size which Lenox Laser will be able to drill, calibrate, and certify your flow rate for your specific application in almsot any type of disc, VCR Gasket, Gland, Conflat, Barb/Luer, Nipple, Set/Hex Screws, and High Pressure or High Temperature Tubing. Custom parts and materials are also available for drilling with a setup fee.
