Fluid Components International FCI ST100 aeration flow meter
In municipal wastewater plants, the activated sludge treatment method requires the pumping of compressed air into aeration basins where a diffuser system ensures the air is distributed evenly for treatment. Flow meters are typically installed in the system piping to help monitor the air that is released into the basins.
The ST100 flow meter is said to provide accurate performance over a wide flow range, ease of installation, low maintenance requirements and digital bus communications versatility, including Profibus PA compatibility. Digital bus communications ensure flow meters and other process automation field devices are interoperable and compatible through an industry standard bus, and Profibus PA includes many functions that simplify the handling of field devices.
The meter gives wastewater plant engineers device flexibility while providing accuracy in harsh environments. Profibus PA communication facilitates plant system retrofits through a seamless integration process for new field devices. The meter’s insertion-style configuration makes it a simple drop-in replacement where older technology meters were installed previously in wastewater plants. Engineers and technicians can easily manage multiple fluid flow process variables and configure the meter remotely from the safety of the control room.
The flow meter is a versatile communication solution and, if a plant’s communication needs change, the meter adapts with a plug-in card replacement that can be changed out in the field. It features a graphical, multivariable, backlit LCD display/readout providing continuous display of all process measurements and alarm status, and the ability to interrogate for service diagnostics.
The user-friendly product stores up to five calibration groups to accommodate broad flow ranges, differing mixtures of the same gas and multiple gases, and obtains up to 1000:1 turndown. An onboard data logger features a removable 2 GB micro-SD memory card capable of storing 21 million readings.
The meter can be calibrated to measure virtually any process gas, including wet gas, mixed gases and dirty gases. Designed for rugged industrial processes and plants, the meter includes service up to 454°C. It is approved for hazardous environments, including the entire instrument, the transmitter and the rugged, NEMA 4X/IP67-rated enclosure.
