About Us

In 1911, with his wife and children as his original workforce, Joseph Meriam began manufacturing U-Type Manometers in his garage. The need for durable, accurate pressure measuring instruments in the industrial revolution was driving the growth of the company. Within a few years, demand for Meriam products forced Mr. Meriam to move his business into a larger facility and hire a full workforce. Years later, the growing need for the overhaul and repair of the stationary gasoline engine, one of Meriam’s other areas of expertise, became another stimulus to the growth of Meriam. The company’s work with power-generating gasoline engines led to the development of flow-measuring devices, one of Meriam’s core technologies today. To accommodate the repair work, the facility was expanded just in time to assist in the war effort. During the war years and afterward, Meriam expanded the manometer line to contain hundreds of different configurations for different applications. The instruments were adapted to work in manufacturing processes to measure differential or gauge pressures. Absolute and vacuum gauge manometers were designed for use in everything from aviation to laboratories. Other products were added to the line, such as differential pressure bellows gauges for heavy-duty applications. The flow product line continued to expand with the addition of annular average pitot tubes, laminar flow elements and orifice plates and flanges. Meriam had a mechanical solution to nearly every pressure or flow measurement need and many of these products are still in demand today. The Meriam family sold the Meriam Instrument Company to the Scott & Fetzer Company in 1969. Today Meriam remains a Scott Fetzer Company. Meriam manufactures reliable and accurate process measurement instrumentation including mechanical and electronic pressure indicators, analog and digital pressure transmitters, primary flow elements, handheld pressure, temperature and loop calibrators, handheld HART communicators, process indicators and complete flow systems. Meriam products are used around the world in industries as diverse as Chemical, Petrochemical, Oil & Gas, Utilities, Automotive and Laboratory. Today, the company is recognized as a leading supplier of instrumentation and test and calibration equipment, utilizing the latest advances in technology and design while delivering superior performance. We are committed to providing uncompromising quality products with an impeccable support experience.
