About Us

Precision Flow & Thermal Energy Measurement, Engineered in the USA.

Who We Are

Founded in 1984 and headquartered in Denver, CO, USA, Ogryan Industrial Technology Co.,Ltd is an American manufacturer specializing in the design, production, and global distribution of high-accuracy flow meters and thermal energy meters. All of our instruments are manufactured at our facility in Montbello Industrial Park, Denver, Colorado. From industrial plants to municipal utilities, our instruments help customers measure the resources that power their operations — water, steam, gases, and thermal energy — with uncompromising accuracy and reliability.

Our Story

What began as a small instrument workshop serving local utilities has grown into a trusted supplier to process industries and energy utilities across North America and beyond. Over the past 40 years, we have remained focused on one thing: building measurement instruments that engineers can rely on — meter after meter, installation after installation.

What We Measure

Our product portfolio covers two core areas:

Flow Meters — including Electromagnetic flowmeter , Ultrasonic flowmeter, Turbine flowmeter, Vortex flowmeter

engineered for accuracy across a wide range of pipe sizes, media, and operating conditions.

Energy Meters — BTU / thermal energy meters for heating, cooling, and district energy systems, helping facilities track and optimize energy consumption.

Every meter is matched with application engineering support to ensure the right fit for each installation.

Industries We Serve

Water & Wastewater · Oil & Gas · Chemical & Petrochemical · HVAC & District Energy · Food & Beverage · Pharmaceutical · Power Generation

Quality You Can Trust

Accuracy is not a feature — it is our foundation. All instruments are manufactured under a  ISO 9001 certified quality management system, and each unit is individually calibrated with NIST-traceable standards  before leaving our facility. Certifications include  CE / ATEX / UL / NSF , ensuring compliance with the international standards your projects demand.

Global Reach, Local Support

Through our distribution network in North America, Europe, Asia, we provide responsive technical support, spare parts, and application expertise — so that when you choose Ogryan Industrial Technology Co.,Ltd , you get more than an instrument. You get a long-term measurement partner.

Our Commitment

We measure more than flow. We measure trust. Every decision we make — from component selection to final calibration — is guided by three principles: precision, reliability, and partnership.
