Terminal Automation Solutions (TAS) – Megi Control Systems Pvt. Ltd.

The BJZT Series Multi-Point Thermometer is designed for accurate temperature measurement of liquids stored in tanks. It provides reliable average temperature calculations through multiple sensing points and can simultaneously monitor the water/oil interface level when equipped with a capacitance sensor. The system supports both RS485 Modbus and HART communication protocols, making it ideal for integration with tank gauging and inventory management systems.
Engineered for demanding industrial environments, the BJZT Series delivers stable performance even under harsh and corrosive operating conditions.

Key Features

• Accurate liquid temperature measurement throughout the tank.

• Provides average liquid temperature from multiple sensing points.

• Supports up to 16 temperature measurement points.

• Optional capacitance sensor for water interface level detection.

• Compatible with RS485 Modbus and HART communication protocols.

• Suitable for operation in harsh and corrosive environments.

• Fast response time ensures highly accurate measurements.

• Robust construction with reliable protection for extended service life.

Function

The BJZT-IV Multi-Point Thermometer is specifically designed for temperature monitoring in both custody transfer and inventory control applications. The instrument integrates temperature sensing with water/oil interface measurement, providing comprehensive tank monitoring capabilities.

Measured temperature and interface data can be transmitted to external systems through HART or Modbus communication, or the device can operate as a standalone measurement solution.

Applications

• Storage tank temperature monitoring.

• Custody transfer systems.

• Inventory management and control.

• Water/oil interface level measurement.

• Petroleum, chemical, and process industry storage facilities.
