Meeting and Exceeding Flow Meter Standards: A Quick Overview

Many McCrometer partners and customers require their flow meters to comply with certain standards in order to be implemented as a part of their flow project. Oftentimes, the standard is well-known and mandatory to operate in many geographic regions. Some are industry-specific, and a few are material-related.

If the acronyms get confusing, and the significance of being compliant isn’t overt, we’ll break it down for you!

ISO 9001

The major standard that McCrometer as a company is certified to the International Organization for Standardization (ISO) 9001:2015, a management standard signifying that a company runs its daily operations in a way that allows for the highest quality manufacturing. This means that no matter who joins the McCrometer team, we have standard work processes in place that are not user-dependent, and our customers receive consistent, quality products from our factory.

McCrometer has been certified to ISO since 1999, achieving the specific ISO 9001 in 2001. This is a 3-year certification that requires external notified body and internal auditing to ensure our business practices are compliant, a feat we’ve accomplished due to McCrometer’s adherence to the VeraltoTM Enterprise System (VES).

Veralto, the parent company of McCrometer, developed VES to allow McCrometer and other sister companies to operate on core values that prioritize sustainable processes, superior performance, and quality for our customers. These pillars of operation are what create McCrometer’s environment for continuous improvement and align nicely with the expectations of ISO.

ISO 5167-5

ISO also has a specific standard in place for cone meters, which applies to McCrometer’s V-Cone® product suite, composed of V-Cone, Wafer Cone®, and VM V-Cone®. This directive specifies the installation and operating conditions for the meter, ensuring that the V-Cone meets specifications for criteria like upstream and downstream straight-run, site installation, and more.

Although meters can adhere to the standard by a dimensional check post-manufacture, McCrometer can also ensure each meter is compliant through full calibration over the entire Reynolds range. McCrometer calibrates each meter manufactured in NIST-traceable flow labs and provides customers with a calibration report that includes all points of inspection, so customers have confidence in the performance of their V-Cone. This calibration also allows McCrometer to identify any irregularities in the pipe, a quality control that cannot be found with the dimensional check. Calibration also allows the V-Cone to achieve up to ±0.5% accuracy when tested across the full Reynolds range.


Another standard specific to McCrometer’s V-Cone product line is the Pressure Equipment Directive (PED). Specific to the European Union, this directive states that any piece of equipment pressurized over half a bar must comply with outlined safety standards. McCrometer’s equipment is audited periodically, ensuring our factory meets standards for welding, design, meter testing, and more. McCrometer’s diligent document control and internal processes ensure our company is certified to PED.


Various McCrometer products adhere to the National Sanitation Foundation (NSF) standards, including NSF-61 for drinking water, and NSF-372 for lead content. These safety standards ensure that any materials that touch drinking water are approved by the NSF. McCrometer’s proprietary fusion-bonded epoxy that coats meters like our Dura Mag®, Ultra Mag®, and FPI Mag® (and more!) is NSF-approved for drinking water applications. While some products may not currently have NSF approval, McCrometer is in the process of certifying the entire flow meter product portfolio to the NSF standard.

The wafer-style Ultra Mag is coated in McCrometer’s NSF-approved epoxy.

Many of McCrometer’s products, like those listed above, are ideal for drinking water applications in the municipal industry. For applications in the water industry that aren’t as demanding in requirements, like effluent water or wastewater, additional McCrometer products are applicable. For more information, contact the factory regarding your specific flow project.


Regarding electronics in hazardous locations, the Eurofins MET certification signifies that McCrometer products, like the ProComm converter, meet applicable safety standards and inspections. This is required when customers install flow meter electronics in Class 1, Division 2 locations involving flammable liquids and gasses, combustible dust, and other ignitable conditions. McCrometer meters and converters that are certified for hazardous areas may be installed in application sites that are prone to an explosive atmosphere, such as petroleum refineries, utility gas plants, and water/wastewater treatment plants, among others.

McCrometer Meets Standards

The list of standards that McCrometer adheres to and the certifications our company and products have isn’t complete in this article. There are other ISO standards met that are environmentally oriented, and there is a myriad of material standards met; the list is extensive. McCrometer prioritizes meeting and exceeding these standards as a way of serving our customers and providing the best quality products to the market.

The best way to determine if McCrometer meets a standard or regulation your company or flow project requires is to contact our factory directly. Our experts on staff are familiar with the standards met and can provide additional information upon request.

If your flow project requires a certification that McCrometer doesn’t currently offer, feel free to inform us. We aim to meet mandated standards in all regions in order to provide quality products to global customers.
