Advantages and Disadvantages of Hydrostatic Level Measurement

Hydrostatic pressure and level measurement enjoys a consistently high popularity due to it’s high robustness, high reliability and simple installation of this technology. The following characteristics constitute the greatest advantages and limitations over other measuring principles:


• Proven and established measuring principle with high reliability, fieldtested millions of times

• Robust measuring process, uninfluenced by disruptive factors such as dust, foam, vapour, buildup, contaminants, etc.

• Reliable measurement unaffected by many physical characteristics such as conductivity, dielectric coefficient or viscosity

• Level measurement unaffected by vessel geometry and existing installed equipment

• Simple installation and operation of submersible pressure transmitters and conventional pressure sensors without the need for calibration or adjustment

• Direct contact with the medium

• Numerous alternative design variations and sensor technologies for almost every application


• Unsuitable for bulk material

• Accurate measurement requires either media with constant density or continuous density measurement of the medium
