Hawker Bubbler - Continuous Level Monitoring System

• Suitable for all corrosive & non-corrosive liquids
• Integral continuously rated air pump for depths up to 3m
• Can be used with optional regulated air or inert gas supply
• 4-20mA output and built in analogue depth meter
• 4 fully adjustable set points
• Dip tubes available

The system is designed for use in aggressive liquids which would attack an immersed pressure transducer/ transmitter, air is bubbled into the liquid via a dip tube with a balance chamber to smooth out pressure pulses. The output pressure from the balance chamber is fed by a nylon tube to the transducer, situated in the controller. The transducers output signal is conditioned to provide a 4-20mA signal proportional to the depth and also to provide an integral meter reading. Control is provided by 4 trip amplifiers each providing a volt free contact output. The unit illustrated is available in either 0-1 m or 0-3m ranges. Alternatively larger units can be supplied for ranges up to 30m complete with ancillary pneumatic gear (details on receipt of application specification). The control unit is normally supplied complete with wall mounting plastic enclosure to IP54.
