Hawk Measurement Systems Pty Ltd (Hawk) was established in 1988 following the recognition by directors of the potential of ultrasonics and the application to level and flow process equipment. The company developed its own product range through its research and development program.

 
 
  SULTAN 234    
       
  The SULTAN 234, is a non intrusive acoustic wave transmitter with flexibility, used for measuring liquids and solids.

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 these high powered waves ensures minimal losses through the environment where the sensor is located. Due to this high powered emitted pulse, any losses have a far less effect than traditional ultrasonic devices. More energy is transmitted hence more energy is returned. The receiver circuitry is designed to indentify and monitor low level return signals even when noise levels are quite high.

The measured signal is temperature compensated to provide maximum accuracy to the outputs and display.

  ORCA    
       
  The ORCA series Sonar will measure up to two density interfaces simultaneously, either bed level or RAS blanket and floc/fluff layer or clarity of water, using the new ORCA Sonar hardware.

The ORCA series Sonar transmits a sound pulse through the water (liquid) towards the blanket/interface at the bottom of the tank. The pulse is reflected off the blanket/interface back to the sonar transducer, which is interpreted by the sonar transmitter, compensated for temperature and provides a distance reading to the blanket/interface or height of blanket/interface from the bottom up. An analogue output or comms based output tracks this blanket/interface.

The ORCA series also provides a second independent output that can be programmed to track either the clarity of the water (liquid) monitoring the change of suspended solids, or other stratified interfaces or, the fluff/floc layer (where the interface moves independent of the RAS blanket/bed level and needs to be monitored to prevent overflow into the launders).

The ORCA processing software monitors the operating efficiency of the sonar transducer. As the efficiency drops off, due to build-up of scum, air bubbles, scaling etc. to the transducer diaphragm, the automatic cleaning mechanism will remove all scum and attached solids to restore the sonar transducers optimum efficiency.

 
     
 

 
     
  MICROWAVE PULSE SWITCH  
       
  Point level switching for presence or absence of most solid and liquid materials. Environmentally and personally safe replacement for nucleonic switches. Not restricted by OSHA or FCC regulations. Caution sign posting not required.

The Hawk Microwave Pulse Sender-Receiver Remote System is comprised of three electrically isolated units:- the sender unit, three receiver units and amplifier unit. The Integral System is comprised of two electrically isolated units;- the send and the receiver unit. The Sender-Receiver units are mounted facing each other. For best performance it is essential that they be mounted securely and correctly aligned.

The sender emits a burst of microwave energy toward the receiver, which is designed around a tuned microwave detector. This burst of energy is transmitted approximately 200 times each second. While the line-of-sight is interrupted by a sufficiency reflective or absorbent material the energy will not reach the receiver, and therefore the receiver will not detect the transmission.

The receiver is designed to switch a relay when it's detector changes state. Time delays between detector change and relay switching is set via two single turn potentiometers; there is a potentiometer for the make (signal detected) delay and another for the break (signal interrupted) delay. In each case the relay will switch only after the detector state has been maintained (since it's change) for the respective time: any further change of state during a time-out period will override the previous change.
