Liquid Flow Meter Calibration

Liquid Flow Meter Calibration Services By Graftel ISO 17025 Certified

Graftel maintains four NIST-traceable primary 700 GPM liquid flow meter calibration systems utilizing water as the calibration medium. Each systems uses a high accuracy Coriolis meter as a secondary standard and its own gravimetric time-mass system as a primary standard. These four systems cover overlapping ranges so that they may be checked against each other.

Water Flow Meter Calibration Systems

Primary A

The system’s flow rate range is 0.001 to 0.5 gpm, (0.001 to 1.89 lpm). The pressure range is 0 to 100 psig, (0 to 69 bar). The best measurement capability is 0.06% of reading.

Primary B

The system’s flow rate range is 0.05 to 16 gpm, (0.189 to 60.8 lpm). The pressure range is 0 to 100 psig, (0 to 69 bar). The best measurement capability is 0.06% of reading.

Primary C

The system’s flow rate range is 1 to 100 gpm, (3.8 to 380 lpm). The best measurement capability is 0.06% of reading.

Primary D

The system’s flow rate range is 50 to 700 gpm, (190 to 3400 lpm). The best measurement capability is 0.10% of reading.
