In industries where flammable gases, volatile liquids, and explosive atmospheres are part of daily operations, measurement technology must do more than deliver accuracy — it must ensure safety, reliability, and regulatory compliance. Servo tank gauges are one of the most trusted solutions for high-precision level measurement in hazardous area installations, especially in oil & gas, petrochemical, chemical storage, and LNG facilities.
Why Hazardous Areas Demand Specialized Gauging
Hazardous areas (classified as Zone 0, Zone 1, or Zone 2 under ATEX/IECEx standards) contain explosive atmospheres formed by:
Flammable gases
Vapors from hydrocarbons
Combustible chemical fumes
Any electrical equipment used in these environments must be designed to eliminate ignition risks. This makes instrumentation selection a critical engineering decision.
Servo tank gauges are engineered specifically to operate safely in these high-risk conditions.
Performance Advantages in Critical Applications
Safety is essential — but performance matters just as much.
✔ High Measurement Accuracy
Ideal for:
Custody transfer
Inventory reconciliation
Loss control
Precise readings reduce financial discrepancies and improve operational transparency.
✔ Interface Level Detection
Servo gauges can detect oil/water interfaces in storage tanks, which is crucial for:
Crude oil storage
Chemical separation processes
Wastewater management
✔ Density Measurement
By analyzing buoyancy, servo systems can estimate product density, supporting:
Product identification
Quality control
Process optimization
In hazardous area installations, measurement systems must balance precision, durability, and uncompromising safety. Servo tank gauges achieve this balance through explosion-protected design, intrinsically safe electronics, and highly accurate servo measurement technology.
