Drawing on 100 years of history, Sparling manufactures some of the most robust flow meters on the market. With the proper service and calibration at the factory, our meters can last decades.

​

The Service, Overhaul, Test, and Re-certify (SOTR) Program makes sure meters stay accurate and effective. Meters arrive worn and out of calibration and leave fully rebuilt and recertified. Furthermore, meters are flow test certified in our NIST traceable flow lab, one of the largest in the country.

Sparling’s factory is the only authorized Sparling Flow Meter service center. ​
