Apparatus for routine monitoring and automatic reporting of electrical power and gas utility usage also provides means for detecting and reporting to the relevant utility companies, fire department, and other emergency responders the development of local hazards on premises at which one or more utility usage meters are installed, including the occurrence of a fire, a gas leak, or any other circumstances such as medical emergencies that demand fast response. Such reporting can include automatic reporting of both zero or excess electrical current draw or zero or excess gas usage. The system is clock driven, fully programmable, and expandable to such other types of sensors as would detect and report on such circumstances as the presence of noxious materials as in a chem / bio attack. A permanent record of all reported events is made.

The invention relates to a method for producing coated acidifier granules for a feed. The method comprises the following steps of: atomizing and adsorbing lactic acid; placing a proper amount of carbon black into a one-step granulator; spraying the lactic acid into the granulator for atomization and adsorption by a peristaltic pump; crushing citric acid, fumaric acid and malic acid and screening the materials with a 60-mesh sieve; mixing the materials and a lactic acid adsorbate; and adding a coating agent into a high-efficiency mixer granulator for coating and granulating to obtain the finished product. The acidifier prepared by the method is combination of organic acids, so that the releasing of the acidifier can be slowed down. The granules are coated with protective films, so that thecontact with an alkaline substance in the feed is reduced and the acidification effect of the granules is enhanced. The organic acid and other antibacterial substances can be produced by promoting the growth and mass propagation of beneficial bacteria such as lactobacillus and the like, so that the pH value in the gastrointestinal tract is further reduced and the growth of harmful bacteria is suppressed. The organic acid gradually released in the alimentary canal has a complexing effect; and the absorption in small intestine can be promoted after the organic acid is complexed with trace elements in the feed.
