Overview
Sierra’s BioTrak™ 645S/745S shares many of the basic features and benefits of the powerful 645i/745i at a more economical price. Like the 645i / 745i, it meets the rugged demands of municipal and industrial wastewater plants where aeration, digestion, and cogeneration play pivotal roles. BioTrak makes operators smarter and their processes more reliably efficient.
BioTrak is designed specifically for plant engineers focused on renewable wastewater processes where healthy microbial growth is crucial. It provides the precise measurements of gases required to optimize aerobic and anaerobic treatment and produce biogas.
Simple. Fast. Effective.
The BioTrak is easy to install, operate and adjust in the field to avoid costly and time-consuming delays. BioTrak comes with an onboard digital platform: DigiSense™, BioSelect™, and BioView™. They gather, preview, and deliver the data that supports your processes and meets regulations.
Sierra BioTrak’s proven technology makes trust possible. And with reduced maintenance over the lifetime of the instrument, BioTrak significantly lowers cost.
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.
BioView Features
- Quick access to all configuration parameters with pop-up windows and pull-down menus
- Selection of measurement units, flow and temperature ranges, alarm settings and more
- Print or save a BioCal Calibration Validation Certificate
- Set alarms; display alarm codes
- Simulation mode used to align 4-20mA output with the input to the customer's PLC/DCS
- Raw data to be viewed to diagnose or troubleshoot your meter
- Data logging to an Excel® spreadsheet
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.
