Abstract: A remaining-LP-gas display control apparatus includes a consumption obtaining unit that obtains daily gas consumptions in a tank, a consumption predicting unit that predicts future daily gas consumptions for a set number of days such that each future gas consumption is predicted based on the latest gas consumption on the same day of the week included in the gas consumptions obtained by the consumption obtaining unit, a replacement date predicting unit that predicts the amounts of gas remaining in the tank and a date on which the gas remaining in the tank will be used up by using the obtained gas consumptions and the predicted future gas consumptions, and a display control unit that controls a display unit to display an image in which remaining-gas information is superimposed on a location where the tank is placed by using the predicted date and location information.

Abstract: An acquisition portion obtains daily gas consumption amounts of tanks from gas meters. A consumption amount predicting portion predicts future daily gas consumption amounts for a first set number of days using latest gas consumption amounts having the same days of the week among the gas consumption amounts obtained by the acquisition portion. A replacement day predicting portion predicts the day on which the remaining gas amount in the tank becomes zero using the gas consumption amounts and the future gas consumption amounts for the set number of days. An extracting portion extracts the installation address of the tank for which the remaining amount is predicted to become zero on the day after a second set of days from a set period. A planning portion creates a delivery plan for delivering a new tank to the address extracted by the extracting portion 14 within the set period.

Abstract: An acquisition portion obtains the daily gas consumption amount of a tank from a gas meter. A consumption amount predicting portion predicts future daily gas consumption amounts for the set number of days using the latest gas consumption amount having the same day of the week among the gas consumption amounts obtained by the acquisition portion. A replacement day predicting portion, as a remaining amount predicting portion, predicts the remaining gas amount in the tank using the gas consumption amounts obtained by the acquisition portion and the future gas consumption amounts for the set number of days predicted by the consumption amount predicting portion.

Abstract: A shutoff valve adaptor and a measuring unit adaptor are resin members and each of them has an elastically deformable hooking claw. Each of sheet metal members has a hooking target portion. The shutoff valve adaptor is mounted to the sheet metal member by a snap-fit portion comprising the hooking target portion and the hooking claw hooked to the hooking target portion, and the measuring unit adaptor is mounted to the sheet metal member.

Abstract: A flow meter includes: a measuring portion having rotors and provided on a pair of shafts positioned horizontally; a sensor that measures a pressure and a temperature within a flow path of the measuring portion; a front side panel that supports front side components of the measuring portion; a front cover that covers the front side components of the measuring portion; a main substrate that is installed in the front cover and collects a signal from the sensor; and a counter displaying portion that displays the signal from the sensor outputted from the main substrate. The sensor is assembled in the tip end of a cylindrical sensor case, the sensor case is inserted into the front side panel through an insertion opening formed in the front cover, the sensor is installed within the front cover, and the sensor and the main substrate are connected to each other.

Abstract: In a cage-type of pressure reducing device, fewer small holes are formed in a bottommost rank of an outer peripheral variable cage portion than a per-rank number of small holes of other ranks. Moreover, a bottom end portion of a blocking wall surface of a plug is formed slanted so that an inner peripheral variable cage portion side is positioned higher than an outer peripheral variable cage portion side.
