Continuous Level Measurement

HAWK offers a range of continuous level measurement products for various applications

SULTAN 234 – Acoustic Wave Technology

The SULTAN 234 emits a high powered acoustic wave transmit pulse which is reflected from the surface of the material being measured. The reflected signal is processed using specially developed software to enhance the correct signal and reject false or spurious echoes.

The transmission of high-powered acoustic waves ensures minimal losses through the environment where the sensor is located. Due to the high-powered emitted pulse, any losses have far less effect than would be experienced by traditional ultrasonic devices.

SULTAN Sonar – Sludge or Submerged Interface Level Measurement

To optimize performance in each interface application under all process environments:
HAWK has developed a powerful low frequency transducer to penetrate through the suspended solids and capable of measuring the sludge bed level at the bottom of a clarifier or the lightest flocculent layer.

To optimize performance under all process environments in each interface application:
HAWK uses one transducer with a frequency and power level that is applicable to the density of the interface and process conditions expected in the tank. Also, HAWK can guarantee performance for controlling pumps etc, rather than for monitoring purposes only.


Guided Radar – TDR

The Guided Radar range is ideal for the measurement of liquids, powders and granules to a range of 20m. This technology is not affected by pressure, temperature, viscosity, vacuum, foam, dust, changes in dielectric constant, or coating of the probe.

The Guided Radar series can measure virtually any product with a dielectric constant (Dk) greater than 1.3.


ORCA – Sonar Level System

The ORCA Sonar Series transducer emits a high-powered acoustic pulse, which is reflected from the interface density selected. The reflected signal is processed using specially developed software algorithms that eliminate lighter floating densities and stratified layers, allowing measurement of “RAS” or “BED” levels.

It can be calibrated to measure lighter densities like “FLOC” or one of the outputs could be used for a “CLARITY” output, similar to a basic turbidity transmitter measuring solids in suspension.
