Explore Liquid Flow Capabilities – Now Broader Than Ever

We provide both onsite and laboratory liquid flow meter calibration using advanced primary standards and manufacturer‑specific procedures. With flow coverage from 0.005 to 400 GPM, our ISO‑accredited facilities deliver high‑precision results for applications ranging from clean water and HVAC systems to corrosive chemicals and high‑purity manufacturing.

Our liquid flow calibration services support a wide range of processes, fluid conditions, viscosities, and meter types—ensuring stable, drift‑free performance across all operational environments.

Standard calibration will be performed using water at ambient temperature unless otherwise requested or the manufacturer calls out a specific fluid/viscosity. Upon request, we can perform calibrations with a viscosity range of 1 to 50 cSt (centistokes), using a combination of water and propylene glycol.

Why Your Liquid Flow Meter Needs Calibration

Liquid flow meters are essential to accurate measurement and control in industries including clean water processing, chemical manufacturing, medical device production, and energy systems. Over time, environmental shifts, fluid properties, wear, and mechanical stress can impact meter performance.
Common causes include: 

check
Sensor wear, turbine blade erosion, or internal deposits
check
Temperature or viscosity changes affecting meter coefficients
check
Signal drift or electronics degradation
check
Build‑up, corrosion, or contamination in process lines
check
Installation stresses or vibration
check
Flow profile distortions and system disturbances

From industrial process control to high‑purity chemical manufacturing, Transcat ensures your flow meters operate with the precision and reliability your applications demand.
