Flow Meter Rehabilitation Services
Rehabilitation services to restore meters to original operating specifications
Although Primary Flow Signal often recommends replacing aging Venturi flow primaries with new high-performing HVT flow meters, budgets do not always allow for full unit replacement.
To bridge that gap, PFS created the Meter Rehabilitation Program to restore existing meters to their original operating specifications. Venturi primaries are durable by design, and their straightforward construction makes them well-suited for expert rehabilitation. Done correctly, rehabilitation can recover performance and accuracy at a fraction of replacement cost, often in just a few days.
Depending on meter size and site conditions, Venturi meters can be rehabilitated in the field or at a factory. Flanged insert-style meters and meters made from uncommon materials can often be restored. For every project, PFS develops clear technical specifications to define scope and protect quality.
Common Problems Addressed by the PFS Rehabilitation Program
- Plugging of impulse taps
- Plating, corrosion, or scaling of interior surfaces
- Contaminated flow primaries

Customized flow meter rehabilitation plans, built around your meter and your goals:
Every Venturi has a different history, operating environment, and performance target. That’s why we start by understanding what’s happening in your system and what you need the meter to deliver going forward. From there, we recommend the right scope of rehabilitation and testing so you can restore performance with confidence and plan the next steps clearly. Our services can include:
- On-site evaluation and rehabilitation recommendations
- Factory rehabilitation at a PFS facility
- Independent lab calibration from leading academic and commercial facilities
- NIST-traceable calibration through the PFS in-house calibration facility
- Recalibration support for meters and primaries from other manufacturers
Benefits of Flow Meter Rehabilitation
- Lower cost versus the purchase of a new meter
- Conserves original piping, structures, and meter
- Improved accuracy, range, and performance
- More durable and reliable compared to alternative technologies
