HPPP480 Calibration system for gas meters with natural gas
The calibration system serves as a standard for the calibration of gas meters of natural gas. The supply of natural gas occurs directly from a pipeline. The gas used for calibration is then fed back into the pipeline. The system consists of the piston prover as a primary standard. Sonic nozzles for flow stabilization and as secondary standard. Turbine meters as reference standards. The Piston prover is traceable to the sizes both in terms of length and time. The system is optionally equipped with a calibration device for the diameter and length of the measuring tube.
Options
Nozzle register with calibration as a secondary standard
Calibration set-up for diameter
Calibration set-up for length
Gas temperature control
Features
High-precision calibration standard: Uncertainty up to ≤ 0.07% (k=2)
Variable calibration pressure up to 100 bar
Traceability to the SI units in length and time
