Liquid Meter Calibration Facilities APU-011
The automated calibration system APU-011 is designed for automated verification, graduation, and calibration of liquid meters and mass flow meters using three measurement methods.
The system ensures high accuracy and reproducibility of results, allows for testing within a wide range of flow rates and pressures, and significantly reduces the time required for calibration procedures.
APU-011 can be used both in state metrological centers and in industrial laboratories of enterprises that operate or manufacture measuring instruments.
The company manufactures automated calibration systems for liquid flow meters of the APU-011 type in the following modifications:
- APU-011/40 — with a flow range from 0.085 to 40 m³/h;
- APU-011/80 — with a flow range from 0.085 to 80 m³/h;
- APU-011/180 — with a flow range from 0.3 to 180 m³/h;
- APU-011/600 — with a flow range from 0.45 to 600 m³/h.
