The thermal flow meter with two-way measurement and reverse flow detection
Endress-Hauser has successfully installed more than 100,000 t-mass flowmeters worldwide. Whether it is compressed air, natural gas, inertage gas or oxygen: anyone who wants to record gas flows with state-of-the-art measurement technology is no longer forced to make concessions. The sensor design and the unique control functions of the Proline t-mass leave nothing to be desired in terms of optimal process control. Even in the event of significant changes in process conditions, gas flows can be measured with unmatched accuracy.
Robust sensor design for long-term operation with low maintenance - in line version for DN 15 to 100 (1/2 to 4") and insertion version for DN 80 to 1500 pipes (3 to 60")
Global process control: out-of-the-ordinary control and alert functions for condensate detection, flow direction or reverse flow
Gas Engine: 22 gases to select and corresponding gas mixtures with up to 8 components
High-level process control: excellent measurement accuracy (±1.0%), repeatability (±0.25%) storage (up to 1000:1). For process temperatures up to 180 degrees Celsius (356 degrees Fahrenheit) and pressures up to 40 bar (580 psi).
Maximum security: SIL compliant aircraft according to IEC 61508
High operational security: Heartbeat technology for diagnostics, monitoring and control of devices in the process
In many industrial sectors, thermal flow meters have long been used for pure gases and gas mixtures - e.g. in CVC (heating, ventilation, air conditioning), for measuring torch and combustion gases, in facilities with air, oxygen, nitrogen or argon, for monitoring natural gas consumption or for carbon dioxide in the food industry. Proline t-mass F/I 300/500 opens up new possibilities for process control, quantity measurement, leak detection, cost allocation and energy management.
Gas Engine - for maximum process flexibility
The Proline t-mass 300/500 measurement system is equipped by default with the Gas Engine. This software offers users exceptional benefits:
Accurate measurement of pure gases and gas mixtures for current operating conditions
Calculating additional process variables such as throughput speed, reference density, corrected volume flow and energy flow
Dynamic correction in case of changes in pressure, temperature and gas composition
Change of programmed gases without recalibulated
Robust and industry-optimized
The T-mass F and I sensors are exceptionally robust, allowing them to withstand pipe vibrations, solid particles in gases or process fluctuations such as temperature shocks. Thanks to its innovative patented design, t-mass is ideal for long-term operation with low maintenance. All parts in contact with the fluid are made in stainless steel and are NACE MR0175/MR0103 compliant. For gases forming a coating in the pipes, the sensor can be removed for cleaning operations, without altering its performance.
Heartbeat technology - for maximum operating security
Heartbeat technology, another strong point. Integrated into all Proline measuring devices, this verification feature allows for permanent self-diagnosis with maximum diagnostic coverage (>95%) as well as a traceable metrological check that is being processed. All of this reduces complexity and risk in the installation and increases its reliability and availability.
Transmitters for simple system integration
Different transmitters are available for the T-mass F and I sensors: Proline 300 (compact version) or Proline 500 (remote version) with up to four inputs and outputs. They allow simultaneous measurement of mass flow and energy flow, flow speed, gas temperature, and corrected density and volume flow. Access to all measurement and diagnostic data is possible at any time through digital transmission via HART or Modbus RS485, as well as via Wi-Fi or via inputs and outputs that can be combined at will.
