Wastewater Thermal Mass Flow Meter

DigiSense™ Sensor
DigiSense is the state-of-the-art sensor technology used in BioTrak. The thermal sensor interfaces directly with the BioTrak microprocessor for greater control, precision, and programmability. DigiSense accurately responds to changes in process variables (gas flow rate, pressure, and temperature) to determine mass flow rate, totalized flow, and temperature.
 
DigiSense’s correlation algorithms allow the meter to be calibrated on a single gas in the factory while enabling the user to select other gases in the BioSelect menu.
 
BioSelect™
To meet the monitoring needs of Process Engineers, BioSelect allows users rapid gas selection or digester gas mixing from a pre-calibrated list of gases, including air, methane, and digester gas mix in the field.With an optional on-board 2-line x 16-character backlit display, operators can view flow rate, total, elapsed time, process gas temperature, and alarms. The display is also used with the configuration panel to access flow meter settings, such as 4-20mA and pulse output scaling, pipe diameter, zero flow cutoff, flow filtering (damping), display options, and high or low alarm limits.
 
BioView™
Sierra’s BioView advanced software is a free PC-compatible application available for download from Sierra’s website. Connect your Windows-based laptop or PC to the meter using the USB port interface to access meter data and configure the meter’s settings.

BioCal™ Calibration Validation
For customers needing a quick and easy way to verify the meter's calibration in the field, BioTrak offers BioCal™. Initiate this feature through the meter's optional display configuration panel or the BioView software. The test takes less than five minutes to run and produces a pass/fail result afterwards.
 
Using the BioCal test with BioView software, you can produce a Calibration Validation Certificate upon conclusion. The certificate will show the date and time of the test along with meter data such as firmware version and meter serial number. This in-situ calibration validation helps operators comply with environmental mandates and eliminates the cost and inconvenience of annual factory calibration.
