Air & Gas Mass Flow Meter, Thermatel

Magnetrol International has announced the release of the Thermatel® Air and Gas Mass Flow Meter, enhanced Model TA2. At a first glance the enhanced model looks identical to the original design but it's much more. All standard input voltages (AC and DC) are accepted and the rotatable housing allows positioning of the display to the customer’s liking. The display, two lines with sixteen characters each, is now backlit; this allows easy reading in bad weather conditions or dark environments. The four push-button keypad facilitates easy configuration allowing the customer to make modifications in the field. The enhanced model TA2 can be calibrated for one or two different gasses or two completely different ranges, thus also increasing turndown ratio or providing more flexibility. By updating the sensors and sensor design, higher velocities can be measured, and a faster response to changing conditions is obtained. In addition, the new design reduces blockage of flow through the window and reduces orientation sensitivity. There is also a second optional mA output for temperature or flow. Using HART® and PACTware™ is strongly advised as it is helpful for trending, changing any configuration and use for diagnostic purposes. The obtained history log is kept in a non-volatile memory so it can be easily retrieved should there be a need. While this is a SIL 1 device the enhanced model TA2 has a Safe Failure Fraction (SFF) of 88.4%. This amongst the highest for this type of devices. This is important when used in a safety system.
