Did you know Sierra has a special team called OEM & Custom Solutions Group?  This team of engineers and technicians is dedicated to meeting the need for custom products. By utilizing nearly 40 years of  flow meter design experience, we modify any existing product to meet original equipment manufacturer (OEM), private label or general customer special needs. We have an engineering library housing  literally thousands of successful customs and modifications. When you contact us, this is usually where we start because, more often than not, we have done your special application at least once before! Sierra can also assist you in designing a custom mass flow solution from the ground up.  All custom instruments are fully warrantied and tested to assure they meet specifications.  And best of all, many times we will custom engineer at no extra charge. Try us! We love this stuff.  Check out some examples...
