We put a high value on the urgency that's inherent in the flow calibration and repair industry. Our many global locations help us streamline logistics and route customers to the closest service center in North America, Europe or Asia. We even get service and repair work from competitors because the highest-quality calibration just wasn't getting done. We quickly step in and get it done!"
Factory-Direct Flow Meters Means Low Overhead
"We maintain a lean, very competitive operation that often runs 24-hours a day if necessary," explains Sierra President Matthew Olin. "This efficiency and productivity means competitive prices. And because we are the manufacturer, we give you timely responses to questions and draw from over 40 years of flow calibration and manufacturing expertise. With factory-direct service, our team also has the resources to service your instrument quickly and without the hassle of dealing with a third party, thus maximizing your up-time," explains Olin.
Laboratories, Primary Standard & NIST Certified
Since 1973, and in support of our global growth strategy, Sierra has steadily built up our flowmeter calibration and repair capability following our philosophy that a flow device for air, gas or liquid measurement is only as good as its calibration. And at the end of the day, we are only as good as our customers' level of satisfaction.
We have Flow Centers of Excellence in USA, Holland and China with an additional five Authorized Service Centers located in Korea, Singapore, India, Brazil, and Mexico. Our global capability includes over fifty flow meter calibration assets ranging from high temperature wind tunnels, closed loop gas calibration systems, primary standard piston provers and bell provers—all traceable to national standards laboratories such as NIST in accordance to Guide 25.
