Techniques

Chapter 1: Techniques for UniversaLevel

This chapter dives deep into the specific technologies and techniques employed within the UniversaLevel philosophy, focusing on how they overcome limitations of traditional level sensors in environmental and water treatment applications.

1.1 Guided Wave Radar:

• Principle: Guided wave radar (GWR) transmits high-frequency electromagnetic waves through a probe, which travel down the guided wave along the liquid surface. The reflected signal is analyzed to determine the distance between the probe and the surface, thus indicating the liquid level.
• Advantages:
  • Insensitive to changes in liquid properties (density, viscosity, dielectric constant).
  • Suitable for high-pressure and high-temperature applications.
  • Immune to foaming and vapor emissions.
  • Minimal maintenance required.
• Limitations:
  • Can be affected by excessive turbulence and agitation in the liquid.
  • Not ideal for very low dielectric liquids (e.g., hydrocarbons).

1.2 Ultrasonic Level Sensing:

• Principle: An ultrasonic sensor transmits sound waves towards the liquid surface and measures the time it takes for the sound to travel to the surface and return to the sensor. The time difference is used to calculate the distance and subsequently the liquid level.
• Advantages:
  • Non-contact measurement, minimizing wear and tear on the sensor.
  • Suitable for open-top tanks and non-conductive liquids.
  • Cost-effective compared to other technologies.
• Limitations:
  • Limited range and accuracy due to interference from ambient noise and changes in temperature.
  • Not ideal for liquids with strong acoustic absorption (e.g., viscous liquids).

1.3 Hydrostatic Pressure Sensing:

• Principle: A pressure sensor measures the hydrostatic pressure exerted by the liquid at the bottom of the vessel. This pressure is directly proportional to the liquid level.
• Advantages:
  • Simple and reliable technology.
  • Suitable for closed vessels and high-pressure applications.
  • Low maintenance requirements.
• Limitations:
  • Requires a known density of the liquid for accurate level calculation.
  • Not suitable for open-top tanks or liquids with significant density variations.

1.4 Other Techniques:

• Magnetostrictive: A probe with a magnetic float is immersed in the liquid. The float's position is measured using a magnetostrictive wire, providing a continuous level reading.
• Capacitive: A capacitor is formed between a sensing electrode and the liquid. The capacitance changes with the liquid level, providing a measurement of the liquid level.

1.5 Choosing the Right Technique:

The selection of the most appropriate technique depends on factors like:

• Liquid type (density, viscosity, dielectric constant)
• Tank configuration (open or closed, size, materials)
• Environmental conditions (temperature, pressure, turbulence)
• Budget constraints and required accuracy.
