The inner workings of a flowmeter can become worn and fail over time, resulting in inaccurate flow readings. G-M Services is experienced at calibrating propeller style flowmeters as produced by manufacturers such as Sensus, Rockwell, Sparling and Water Specialties. We are also certified to complete meter testing affidavits required by the Harris-Galveston Coastal Subsidence District and the Fort Bend Subsidence District. If your meter is beyond repair, or it is not cost effective to repair your meter, G-M Services can find a suitable replacement for you.
