Key Instruments: Your Flowmeter Manufacturer

Key Instruments is a long-established flow meter manufacturer of precision flowmeters. Years of experience in the field of flow measurement make Key Instruments highly qualified for providing customers with liquid, gas, and water flow meters for countless applications. Our products include flowmeters, valves, and other flow instrumentation accessories.

Today’s developers and buyers demand higher accuracy, greater reliability, and continued functionality under severe operating conditions. Key Instruments manufacturing strives to meet these demands on a daily basis. We utilize automated manufacturing for repeatable high quality and lightening-speed delivery, without compromising accuracy.

Flowmeters at Key Instruments are manufactured to handle problems of viscosity, density, as well as extreme temperature, pressure, and corrosion. At Key Instruments, we design and manufacture tubes of all sizes, shapes, and materials for accurate flow measurements. Glass, acrylic, and polycarbonate are utilized in different ways for their unique characteristics. Consequently, our designers work with customers to understand their product or system needs and to determine the best material for the highest performance.

Different liquid, gas, and water flow meter applications each require distinct resistances to corrosion. Certain flow meter materials are more susceptible to corrosion than others. Key Instruments manufactures flow meters based on your product or system specifications. Our flow meters are guaranteed to maintain their service life in even the most corrosive environments. Prior to manufacturing production, we also consider the type of material that will be measured by the flow meter. Hazardous materials, such as chemicals and sulfuric acids may make the difference between choosing glass, acrylic, or polycarbonate flow meters.

Flow Meter Manufacturing complies with GMP limited testing to samples at the end of the production does not necessarily ensure that all manufacturing standards and regulations have been met. That is why at Key Instruments we closely monitor the manufacturing at our facility. Throughout Key Instruments manufacturing production, we maintain comprehensive documentation, which complies with the Good Manufacturing Practices of the Food and Drug Administration (FDA). We document every aspect from the design, to the manufacturing, to the assembly and test, to the final shipment of our products.

Compliance with GMP regulations allows Key Instruments’ processes to be fully traceable. Following these guidelines also gives our customers the benefit of knowing their project is in good hands. We manufacture flow meters for medical devices, diagnostic products, and anesthesia products; requiring our strict adherence to the FDA’s Good Manufacturing Practices. As flow meter manufacturing improves, so do GMP regulations. Key Instruments stays up-to-date on the latest changes and additions to ensure the best flow instrumentation results.
