Optimize light crude separation

Get better process efficiency

Horizontal light oil separators are suited for high gas-oil ratios and constant flow well streams. Light oil (API >31.1° less than 870 kg/m3 (7.3 lb/gal)) separates faster than other crude oils. Traditional mechanical measurement devices can be challenging in this application. Our guided wave radar eliminates these issues and offers a more accurate measurement.

Benefits at a glance

  • Multiparameter probe for interface measurement. Two current outputs for interface layer and overall level

  • Easy installation and maintenance without any special tools

  • Installation does not require stilling well

  • Same sensor is used for separation and oil compartment of separator

  • No on-site calibration necessary


Most horizontal light oil separators today are equipped with mechanical level and density controls. Mechanical devices need a lot of maintenance and must be adapted to the produced oil. Any change in the produced oil means the measuring device must be changed as well.

Our solution

Our guided wave radar with coaxial probe eliminates any process influences that may occur. The sensor comes pre-calibrated and can be used “out of the box”. This ensures an easy retrofit of existing separators. The sensor can be installed direct into the separator, or in a side pipe (bridle). The same sensor can be used in the separation compartment as also in the oil compartment of the separator. This simplifies spare parts requirements.
