butler-lab-2Given the inherent complications of making high-precision, high-accuracy measurements across a variety of technologies, metrology laboratories don’t want to add additional complexities and potential sources of error in their labs. The DryCal series is designed to overcome some of the common gas flow calibration challenges faced by metrology labs. The list below are a few of the top issues a metrology lab manager may face.

Potential Difficulties of Managing a Metrology Lab:

  • Disruptive re-certification and assurance testing processes for immobile calibration assets
  • Maintaining old, large equipment that may include hazardous materials
  • Managing the length of calibration times required by various standards
  • Improving operator productivity in high-throughput, lean-operating environments
  • Requirements that limit the use of secondary calibration standards
  • Challenges holding accuracy with differential pressure (DP) based secondary standards
  • Minimizing error sources from corrections and conversions
  • Juggling numerous conversion methods to account for calibration gases vs. client’s process gases

drycal-labHow We Can Help

High-Accuracy Calibration Made Easy

Mesa understands that you want your calibrations to be easy to perform when calibrating a high volume of multiple technologies. We are here to take the burden of performing highly accurate calibrations in a highly regulated field off your shoulders.

  • Accreditation You Can Trust. All factory DryCal calibrations are performed in Mesa’s ISO 17025 accredited lab, and all primary measurements are performed with standards directly traceable to NIST.
  • Accurate Calibrations. Perform calibrations at gas flow rates of 0.5 SCCM up to 1500 SLPM with measurement uncertainties as low as 0.15% using a DryCal primary standard.
  • Gas Species Independent Technology. No conversions are required to use DryCal calibrators with multiple gases. DryCal’s positive displacement technology provides users with an accurate, direct flow measurement in any compatible gas right out of the box. No additional factory calibrations to purchase for multiple gas support.
  • High Quality Calibrations for Low Cost and Low Effort. Some gas flow standards require the team to manage hazardous material risks caused by compounds like mercury. Other standards require very precise pressure control in the flow stream. Still others require tight control limits for lubricating fluid temperatures and levels. DryCal standards are mobile, use zero liquids, and don’t require differential pressure limits that are difficult to maintain.

What You Can Calibrate

  • Mass flow controllers
  • Thermal flow meters
  • Orifice plate flow meters
  • Venturi flow meters
  • DP flow meters
  • Pitot tubes
  • Rotameters
  • VA flow meters
  • Turbine flow meters
  • Vortex flow meters
  • Ultrasonic flow meters
  • Gas flow sensors
  • Pressure controllers
  • Flow restrictors
  • Calibrated leaks
  • Pneumatic components
  • Analytical sensors
  • Flow control valves
  • Check valves
  • Secondary standards
  • Transfer standards
  • Master flow meter
  • Portable Calibration Solutions. Compared to older flow calibration technology, such as bell provers, the DryCal products are easy to move around the lab and ship back for quick recertification at Mesa Labs ISO 17025 accredited lab. While some solutions like the DryCal series is designed to fit easily on your lab bench for your demanding high-accuracy requirements, our Defender series is portable and battery powered for quick and easy calibrations in the field with a 1% accuracy.
  • Calibration Automation Made Easy. DryCal products include an intuitive user interface for immediate productivity, and support external control via a serial interface. Scale calibration automation into your lab as needs dictate using our DryCal Pro software or your own custom calibration solution in a paperless or paper-filled lab. Rental standards keep you calibrating through certification cycles or temporarily scale up capabilities to win big jobs.
  • Flawlessly Adapt to Changing Client Requirements.The calibration needs of instrument users are always changing; whether it’s new flow ranges, different uncertainties, added locations, and/or cost pressures. DryCal’s modular construction can easily support new flow ranges by adding flow cells to your lab. With standards for lab or field calibrations, and uncertainties from 0.15% to 1% of reading, DryCal lets you invest in the capabilities your clients actually need.

Regulatory and Compliance

ISO 17025
ISO 17025 is a globally recognized and accepted accreditation obtained by calibration laboratories to demonstrate their competence in providing calibration services.

NIST
NIST is the National Metrology Institute (NMI) for the United States who provides calibration services across metrology disciplines and maintains the US inventory of national measurement standards.

ANSI Z-540
ANSI Z-540 has been partially superseded by ISO 17025 and Z-540 part 3, and is primarily used as an accreditation standard for calibration laboratories supporting operations of select departments of the US Government.

FDA 21 CFR 820.72
21 CFR 820.72 defines the quality system requirements to operate and maintain inspection, measuring, and test equipment used in the production of food and drugs supplied to the US market.

SEMI Test Methods for Gas Delivery Systems
SEMI creates and maintains standards and test methods used by global manufacturers of microelectronics and solar equipment to assist them in specifying system components, maintaining performance specifications, and commissioning and troubleshooting the gas delivery sub-system of process tools.

OIML R137
R137 is a recommendation from the International Organization of Legal Metrology (OIML) intended to standardize terminology, technical requirements, metrological controls, and other factors for flow meters of any technology that measure gases and gaseous fuels that are not liquefied, multi-phase, or steam.
