refinery recently installed two new air compressors in their plant and specified two mass flow meters to measure utility air use and dry instrument air flow rate, as well as total plant output. Their principal objective was to be able to monitor increased air usage or temperature changes that might indicate a leak -- a costly proposition.
The plant engineers selected Sierra's Innova-Mass flow meter because this device "does it all". They would not need to buy and install ancillary devices, such as temperature transmitters or pressure gauges; which saved them approximately $3000 in purchase and installation cost per unit. They also found it advantageous that they could transmit and record a temperature and pressure history on each line. The principal engineer reports that these meters contribute to the plant's overall output quality, since the instrument's features enable the plant technicians to easily accomplish total plant balancing of utilities.
He went on to say that the meters were "really, really easy" to program and configure. He especially values the "nice big, fat buttons, which are so easy to see and use". In fact, he simply handed the meters to a new technician who had no prior training with Sierra's products. With only the aid of the Operator's Manual, the technician was able to install and commission the meters with less than six hours of downtime and without any problems or difficulties.
Our customer reports that both meters have done exactly what we promised they would do!
