In 1955, engineers committed to developing real-world flow metering solutions founded McCrometer. Unable to find the right flow meter for their irrigation system, the original engineers designed their own, and formed McCrometer, based in Hemet, California. Over 60 years later, this solutions-oriented approach still guides the company.

McCrometer is a leading global flow instrumentation specialist. We specialize in the design, manufacture, installation and testing of flow metering solutions. Instrument, process, facility and consulting engineers worldwide have confidently chosen McCrometer’s flow meters for more than 60 years.

Our application engineers, researchers, and designers apply their expertise in flow physics and real-world operating dynamics. The results are some of the most accurate, innovative, and trusted flow meters on the market. Our ISO certified manufacturing facilities and quality control systems are the foundation for being a trusted supplier to fit every customer’s need in diverse markets such as aerospace, agriculture irrigation, chemical and petrochemical, food and beverage, metals and mining, municipal water and wastewater, oil and gas, pharmaceutical, power utilities, pulp and paper, semiconductor and more.
