A Servo Tank Gauge with efficient inventory management capabilities is a high-precision instrument widely used in tank farms, refineries, petrochemical plants, and terminals to measure and manage bulk liquid inventory — especially for custody transfer and critical stock control.
Let’s break down how an STG contributes to efficient inventory management:
What is a Servo Tank Gauge?
A Servo Tank Gauge uses a servo-driven motor to lower a sensing weight (or displacer) into the tank. It precisely measures:
Product level
Interface level (oil/water separation)
Density
Temperature (via integrated temperature sensors)
Real-World Benefits
Improved custody transfer accuracy = financial accountability
Reduced product loss through tighter reconciliation
Faster inventory decisions from real-time data
Automation-ready for unmanned terminals or remote tank farms
Forecasting and analytics via integration with inventory management software
Common Interfaces for Integration
HART
Modbus RTU/TCP
Foundation Fieldbus
Profibus
OPC DA/UA
