Rapid Prototyping of Flowmeters at Key Instruments

In order to make an informed purchase decision on the best flowmeter for your application, Key Instruments offers rapid prototyping services. As a top-notch flow meter manufacturer, we employ skilled design engineers who seek to integrate precise, reliable, and low cost flow solutions into various subsystems and pneumatic assemblies. At Key Instruments, we implement an effective approach that significantly reduces the time it takes to put prototypes into the hands of customers.

Key Instruments rapid flow meter prototyping is geared toward the customer. In order to help customers visualize an exact concept, KI uses rapid prototyping methods to produce parts for immediate customer evaluation. Prototyping allows customers to see their flowmeter in action within an installed setup as well as how it functions and benefits their subsystem or pneumatic assembly. Our engineers construct a prototype model, which serves as the customer’s final hands-on check for dimensional precision, material selection, flow measurement accuracy, and more before full-scale production is initiated.

Rapid prototyping is a critical process that is part of the analysis phase of design and development. During the requirements determination portion of the analysis phase, our design engineers gather information about the properties of the liquid and gas, as well as overall installation, performance, and cost criteria. Additionally, we study the current flow instrumentation system; this information helps us develop the foundation for our flowmeter design.

Advantages of Key Instruments’s Rapid Prototyping


  • Performs fit and function tests of the prototype
  • Reduces machining production time
  • Reduces manufacturers costs
  • Provides user feedback

Fit and function testing of prototypes avoids possible future complications. At an early stage in production we are able to determine if the flowmeter is manufactured to the right tolerances or if another material should be used. Calibration and testing verifies that we have obtained accurate flowrate prototypes prior to committing to the manufacturing process. With the right prototype as a guide, full-scale production runs smoothly and efficiently. Fast cycle times mean less labor, resulting in a better price to customers.

Key Instruments’s rapid prototyping can augment the design and development process because it converts intangible specifications into tangible working models. The user feedback gained from developing a physical flow instrumentation solution is extremely beneficial. What the end users touch and see facilitates an evaluative response that our engineers can employ to modify existing requirements as well as developing new ones.

At Key Instruments, we take pride in providing customers with accurate prototypes to speed up production and reduce costs. Investing in state-of-the-art computerized technology helps us produce the best possible prototype for your application to deliver your products to the market sooner. As a leading flow meter manufacturer, we are constantly evaluating the latest software to turn your vision into reality.
