Servo Level

Servo Level Measurement

Endress+Hauser servo level devices are top‑mounted contact gauges that determine liquid level by balancing a small displacer. A servo motor positions the displacer until buoyancy matches a set force, then converts that position into a level. One instrument can deliver continuous level, liquid‑liquid interface, and density profile for storage tanks.

Endress+Hauser servo level products are valued for millimeter‑class accuracy, strong repeatability, and long‑term stability. The force‑based method remains dependable as product properties and temperatures change. Built‑in diagnostics validate results, and hazardous‑area approvals with overfill options support safety and compliance.

Typical uses include tank gauging and inventory control in terminals, refineries, and chemical plants; custody transfer for fuels and petrochemicals; water‑bottom detection in crude and refined products; and density checks for blending and quality. Servo gauges also suit stilling wells, bypass chambers, and floating‑roof tanks.

Endress+Hauser combines robust mechanics with seamless connectivity. Standard outputs (4–20 mA/HART, with Modbus or fieldbus options), simple top entry, and verification tools lower lifecycle cost. Easy integration with tank inventory systems and DCS platforms turns precise levels into actionable plant data.
