The system keeps track of indoor and outdoor temperature and humidity, wind direction and velocity, solar intensity and rainfall. All of these variables are displayed on a very elegant touchscreen panel that can be wall mounted or set on a table. The display also shows the time and date and has a graphing feature that lets you view the history (last 24 hours or last 8 days) of any of the variables at the touch of a finger.
Take a moment to program in your electric utility rate ($ per kwh) and the unit will tell you the total cost of running the appliance during the time of monitoring. Push the "Cost" button again and it will calculate the cost per day ... another button push = cost per month and one more push forecasts the cost per year.
Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter in 1997. Today, Sierra's completely redesigned InnovaMass® iSeries™ 240i/241i builds on two decades of success measuring five process variables for gas, liquid and steam with one connection. Now, with the latest hyper-fast microprocessors, robust software applications, field diagnostic and adjustment capability, and a new state-of-the-art flow calibration facility, Sierra's vortex iSeries delivers precision, performance, and application flexibility never before possible.
