The TEC-II Volume Conversion Device is an advanced electronic instrument designed to be configured with various types of gas flowmeters. Its primary function is to convert the volume measured in measurement conditions to the volume in base conditions.

Core Functionality

The TEC-II can be set for PT (pressure and temperature correction) or PTZ (pressure, temperature, and compressibility factor correction) based on user requirements. It also functions as an energy measurement device and conforms to the EN12405-1 standard.

Protection and Security

The device features multi-level safety guarantees, including an independent metrology switch, metrology seal, manufacturer code, and user password. Access authority is required for every independent data visit, and data input is done through user interfaces (keyboard or communication).

• Low Power Consumption: Utilizes low power consumption technology, with an internal lithium battery providing an operational life of at least 5 years under defined work mode.
• High Data Security: Equipped with multi-level safety guarantees for access and integrity.
• Dual Signal Input: Capable of parallel HF and LF input for comparison purposes.
• Magnetic Interference Detection: Each stream is designed with a magnetic interference detection interface to detect and judge the presence of intentional magnetic interference and record the event.
• Selectable Compressibility Algorithms: Supports various algorithms for the compressibility factor, such as SGERG-88, AGA92-DC, AGA8-G1, AGA8-G2, AGANX-19, or a fixed value.
