The Instrumentation for Aeration Control Package from Endress+Hauser is geared specifically toward advanced aeration control strategies. Instruments available measure dissolved oxygen, nitrate, ammonium, pH, suspended solids, temperature, air flow rates, air pressures and water levels in aeration basins to provide enhanced and reliable control of a process.
The Endress+Hauser family of aeration control sensors connects to any plant’s PLC or SCADA system via 4-20mA with HART, Profibus or other digital interfaces. Digital communications and advanced diagnostics in Endress+Hauser instruments also simplify maintenance and commissioning.
Liquiline CM442 transmitters and CAS40D sensors – both with the digital Memosens protocol – monitor the ammonium and nitrates of the incoming and/or treated water with a single sensor array that can provide additional parameters such as pH, temperature, chloride and potassium.
Oxymax optical or amperometric dissolved oxygen sensors monitor dissolved oxygen to make sure minimum levels are maintained. With the CM442’s dual channel digital technology, one transmitter can measure ammonium, nitrates, dissolved oxygen, temperature and pH.
The Cerabar S pressure transmitter is available to measure air line pressure. A Prosonic FMU90 ultrasonic or a Waterpilot FMX21 hydrostatic instrument can be used to measure and control level.
