An instrument for pure gases and gas mixtures, Proline t-mass F/I 300/500 helps ensure potable water safety and effluent legislation compliance
Endress+Hauser has introduced a flowmeter that allows plant operators to optimise their disinfection processes for drinking water and wastewater. Proline t-mass F/I 300/500 devices provide gas measurement, and help ensure water quality and safety in accordance with local legislation.
Equipped with Heartbeat Technology for diagnostics and monitoring, the automatic device offers verification without process interruption. A warning function in case of pulsating flow or condensate further enhances the monitoring process. All wetted parts are made of corrosion-resistant steel to ensure compliance stands and long-term operation. The devices come with a backlit display with touch control and can also be operated via a web server and WLAN.
Over 100,000 t-mass flowmeters have been installed in compressed air and gas applications worldwide. Based on this experience, Endress+Hauser developed this new thermal mass flowmeter that supports plant operators in preventing waterborne diseases by ensuring water safety in their disinfection process while allowing them to optimise their maintenance strategies to reduce operating expenses.
Even when process and ambient conditions are fluctuating significantly, Proline t-mass F/I 300/500 ensures high measuring accuracy at ±1.0% with repeatability at ±0.25%. Gas flows with low pressure and a low flow velocity can also be measured with high turndown.
The t-mass F and t-mass I sensors feature robustness, enabling them to withstand such factors as pipe vibrations, solid particles in the gas and process fluctuations, for example temperature shocks. With its innovative sensor design, it is possible to operate the device over the long-term with limited maintenance, thus saving time and money for the user. All wetted parts are made of corrosion-resistant steel to ensure high compliance standards and long-term operation. For gases that form an unwanted coating in the pipe, the sensor can be removed for cleaning work and reinstalled quickly and easily.
T-mass F and I sensors are used at process temperatures up to 180°C and pressures up to 40-bar.
The t-mass F/I 300/500 devices are equipped with alarm functions that are used for detecting unwanted condensate drops on the sensor or pulsating flow. In the case of condensate, this can prevent the emergence of long-term corrosion damage in piping systems. Any device or process errors that may occur are clearly categorised following NAMUR NE107 and immediately indicated. This makes it possible to take fast and targeted countermeasures.
Heartbeat Technology is integrated into all Proline measuring devices and enables permanent self-diagnostics with diagnostic coverage of more than 95% as well as a metrologically traceable device verification without process interruption. For safety reasons, Heartbeat Technology also has a Heartbeat Sensor Integrity test function for detecting changes to the measuring electronics and sensor as a result of extreme environmental and process conditions. Heartbeat Technology reduces complexity and risks in a system and thus increases its reliability and availability.
Proline 300/500 transmitters include a web server as standard. Using a standard Ethernet cable and a laptop – or wireless via WLAN – users have direct access to all diagnostic, configuration and device data without additional software or hardware. This enables targeted and time-saving maintenance and service.
The data storage concept, HistoROM, ensures data security before, during and after service. All calibration data and device parameters are stored securely on the HistoROM data storage module and are automatically reloaded after maintenance work. Therefore, installing spare parts is easy, saves time and thus reduces unnecessary downtimes.
The t-mass F/I 300/500 sensors can be combined with two different transmitters: as a compact Proline 300 version or as a remote Proline 500 version with up to four inputs and outputs. The digital signal processing begins in the intelligent sensor and is the basis for real multivariable measurement. This means that t-mass can simultaneously record multiple measured values such as mass flow, flow velocity or gas temperature for process control, and forward them to a process control system. Complete access to all measurement data, including diagnostic data acquired by Heartbeat Technology, is possible at any time – due to digital data transmission via HART or Modbus RS485 as well as via WLAN or the freely combinable inputs and outputs.
The t-mass F/I 300/500 measuring system is equipped as standard with the Endress+Hauser “Gas Engine”, which is a software-based data set consisting of typical standard gases and their properties. Gas Engine offers an exact measurement of pure gases and gas mixtures for current operating conditions. Users can choose from 22 standard gases or create gas mixtures by combining up to eight of these gases. Gas Engine is also capable of calculating additional process variables such as flow velocity, reference density, corrected volume and energy flow. Other features include the dynamic correction for changes in pressure, temperature and gas composition as well as the possibility to change programmed gases without recalibration. Additionally, Gas Engine incorporates a switching function for two predefined gas groups via the status input, for example for flushing processes with an additional gas.
