Level gauges

Purpose: measurement of liquid level, phase separation boundaries at the enterprises of chemical, petrochemical, power industry and general applicability.

Main advantages:

  • High-precision;
  • Versatility in use;
  • Measurement of liquid, phase separation boundaries under high temperature and pressure;
  • Good protection against sticking;
  • Easy to operate.

Convenient and simple interface allows you to easily configure the level gauge. Thanks to the modular construction and adjustable parameters of the sensing element, easy maintenance is ensured.

A series of radar level gauges GKS LR allows you to solve the most complex problems for any process conditions.

Classic level gauges have a complex design and require a long configuration Radar technology is independent of temperature, pressure, steam and dust. They are ideal for environments where chemical vapors, temperature gradients, vacuum or high pressure are present, such as in oil depots, chemical storage facilities, or where a large measurement range is required.

GKS LR level gauges are designed for optimal operation in hazardous areas and have many certificates and addmission.

Main advantages:

  • Reliability and accuracy — thanks to the signal processing technology-the function of automatic elimination of «false» echo signals reflected from fixed obstacles, ensures the reliability and accuracy of measurements;
  • Easy installation — thanks to a small antenna, the level gauge can be installed on almost any tank;
  • Ease of configuration — programming with a handheld spark-proof IR-programmer or local display buttons enables you to configure the sensor in a matter of minutes.;
  • Remote indicators — thanks to the digital remote indicators, the operator can receive data in the control room or in another convenient place.
