BACnet (Building Automation and Control Network) is a communications protocol that defines the services used to communicate between building automation end-devices and building control systems.ACnet stands for Building Automation and Control network. The BACnet Committee developed the standard with the intention of creating a technically sound and truly non-proprietary standard. They also kept in mind ease of use and did their best to eliminate many of the barriers to implement.
The water is modelled using clear and white silicone mastic. A great deal of care was taken to create the falling water using clear silicone mastic mixed where required with a touch of white. A number of ports were created to the back of the layout. The exits were hidden in the waterfall by silicone 'falling water'.nother problem for models is that dust will gradually land on the water and the effect is lost. If the surface is really hard, it is possible to clean this off with a soft brush, but in the end, a new thin gloss coating has to be applied to keep the whole affair looking wet.
Understanding your mechanical water meter. The mechanical water meters measure water use in cubic feet (one cubic foot equals 7.48 gallons). Tucson Water calculates water usage based on hundreds of cubic feet (Ccf) or per 748 gallons. To read your water meter, first look to see if the meter register has an analog (dial) or digital display. How to read the analog display. Analog displays use straight-reading dials which are read the same way you read your vehicle odometer. The last two digits on the meter dial are dropped when the meter is read. In the example at upper right, the meter reads 9 CCFs.
