Principle

보정 원리

A PTZ Corrector is installed on a gas meter to automatically convert the measured volume (Vm) to the standard-condition volume (Vb) by applying temperature (T), pressure (P), and compressibility factor (Z) — referenced to 0°C and 101.325 kPa.

Temperature Accuracy

0.5 ℃

Pressure Accuracy

0.25 %

Battery Life

Over 4 years (Lithium)
