This range of flowmeters is used for measuring highly corrosive solutions such as nitric, sulphuric, hydrochloric and hydrofluoric acids. It is ideal for measuring aggressive and non-conductive liquids which have proven to be incompatible with most magnetic and mechanical flowmeters.
The long term reliability and stability of the Hoverflo make it ideal for both batch and continuous process operation.
In hazardous areas you can use the flowmeters with the Apollo IS pick-off coil, approved to ATEX II 1G EEx ia IIC T5/T4. The signal can be used in the IS area or transmitted to the safe area using the intrinsically safe P5 preamplifier and suitable barriers.
Principle of Operation
The flowmeter has two turbines connected by a central shaft. The liquid flows through both turbines, spinning the shaft whilst it hovers. The lower turbine has magnets sealed in the rim which are detected by the sensor to generate pulses. The frequency of the pulses is proportional to your flow rate.
The signal can be used for a local display, remote display or converted for transmission to a separate control system. Apollo have a range of instruments to suit all your requirements.
