All calibrations are NIST-traceable to ±0.1% accuracy and include a calibration certificate. We calibrate meters we sell as well as third-party meters from any manufacturer. Salinas, CA facility. Est. 2006.

 

Our Four Calibration Facilities

Gas Loop Calibration  Gas Flow Meters

Our gas loop calibration facility calibrates thermal mass flow meters, vortex meters, and Coriolis meters across a wide range of industrial gases. The loop recirculates gas at controlled pressure and temperature, allowing precise multi-point calibration at the velocities and conditions you actually operate in. Ideal for: compressed air systems, natural gas distribution, methane monitoring, process gas flow verification, and pre-installation acceptance testing.

Gases

Air, N₂, He, CO₂, Methane, Propane

Flow Range

0–100 SMPS / 19,685 SFPM

Pipe Sizes

1/2" – 6"

Meter Types

Thermal, Vortex, Coriolis

Water Loop Calibration  Liquid Flow Meters

Our water loop calibration facility is purpose-built for liquid flow meters. The closed-loop water system maintains stable temperature and pressure while delivering consistent, traceable flow rates across the full operating range of your meter. Multi-point calibration with certificate included. Ideal for: magnetic flow meters, ultrasonic meters, Coriolis liquid meters, process water, wastewater, and chemical dosing applications.

Gravimetric Prover Calibration  Highest Accuracy Liquid

Gravimetric calibration is the gold standard for liquid flow measurement. Flow is measured by precisely weighing the collected fluid over time — no reference meter required. This primary standard method delivers the highest confidence for custody transfer, laboratory, and regulatory applications requiring maximum traceability documentation.

Capacity

100 gal / 1,000 lb

Meter Types

Mag, Coriolis, Vortex, Ultrasonic

Piston Prover Calibration  Low Flow Gas & MFC

Our piston prover calibrates low-flow gas instruments including thermal mass flow meters, mass flow controllers (MFCs), MEMS sensors, and differential pressure devices. The piston displaces a precisely known volume of gas at controlled conditions — ideal for instruments operating at SCCM-level flows where other methods cannot achieve adequate resolution.

Flow Range

1–50,000 SCCM

Gases

Air, Ar, CO₂, He, H₂, N₂

Meter Types

Thermal MFM/MFC, Delta-P, MEMS

Method

Volumetric displacement
