Sierra - Model AdvantageMass TM100 -Economical Industrial Thermal Mass Flow Meter

Need the Features, but Lack the Budget?

Benefit from the powerful features of Sierra`s PowerMass TM500™ at a more affordable cost with the TM100. If your application doesn`t require the TM500’s remote configuration, AC power, or flow range over 25,000 sfpm, Sierra`s AdvantageMass TM100 may be the ideal meter for you.

The TM100 makes you smarter and your processes more reliably efficient. And we`re always here if you need us—Sierra`s promise to customers for 50 years.

Why Thermal?

Sierra`s thermal technology delivers direct measurement of gas mass flow. Unlike differential pressure (dP) meters that measure volumetric flow, it’s simpler to make and maintain, and no temperature or pressure corrections are required. dP requires additional calculations to convert volumetric flow to mass flow, the measurement that most often needs to be reported. That reduces accuracy. Thermal has negligible pressure drop or flow restrictions, significantly reducing expense once the full ownership cost is considered.

DigiSense™ Sensor

DigiSense is the state-of-the-art sensor technology used in the TM100. Unlike other thermal flow sensors, it interfaces directly with its 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 Gas-Mix menu.

Gas-Mix™ Menu

Gas-Mix allows users rapid gas selection or mixing in the field from a pre-calibrated list of 12 gases. With an onboard 2-line x 16-character backlit display, end users can view flow rate, total, elapsed time, process gas temperature, and alarms. TM100’s display is also used with the configuration panel to access flow meter settings, such as 4-20mA and pulse output scaling, pipe diameter, low flow cutoff, flow filtering (damping), display options, and high or low alarm limits.

TM100-View™ Software

Sierra`s TM100-View 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.

View Features

• Get quick access to all configuration parameters with pop-up windows and pull-down menus
• View raw data to diagnose or troubleshoot your meter
• Select measurement units, flow and temperature ranges, alarm settings, and more
• Print or save a TM-Cal Calibration Validation Certificate
• Set alarms and display alarm codes
• Use simulation mode to align 4-20mA output with the input to the user’s PLC/DCS

TM-Cal™ Calibration Validation  

The AdvantageMass TM100 includes on-board calibration verification through the TM-Cal feature. This diagnostic is automated and does not require any additional equipment or removal of the TM100 from process.  TM-Cal takes less than five minutes for completion and can be initiated via the meter’s display, Modbus RTU, or TM100-View software.  When the test is complete, a pass/fail response indicates if the meter requires troubleshooting or recalibration.

Using TM100-View to run TM-Cal results in a calibration validation certificate, it can be printed or saved for compliance with the user’s local regulations and metrology requirements. The certificate is encrypted and includes all relevant information from the test: time and date, meter identification, and pass/fail results.
