Mass Flow Meters - DILO Company, Inc. | Dilo Company, Inc Flow Meter For recording gas quantities from and to the circuit breaker. B152R41/51. SF 6 Mass Flow Meter. The SF 6 Mass Flow Meter can be used to accurately measure the quantity of SF 6 (in lbs/mass) as it is either filling equipment, or during gas recovery. Because the measurement is based on the volume of gas passing through the device, traditional cylinder weighing is not required.
Demand response - Wikipedia response is a change in the power consumption of an electric utility customer to better match the demand for power with the supply. Until recently electric energy could not be easily stored, so utilities have traditionally matched demand and supply by throttling the production rate of their power plants, taking generating units on or off line, or importing power from other utilities.
