摘要： PROBLEM TO BE SOLVED: To provide an electronic gas flowmeter capable of obtaining data on measured gas flow rate by communication means. SOLUTION: A fixed quantity flow rate for every specified flow rate, which is calculated by a flow rate calculation part 3 from a flow rate signal which corresponds to the gas flow rate outputted from a flow rate detector 2, is outputted from a communication control part 7 outward, after the flow rate data signal is processed by a flow rate data processing part 6. When an electronic gas flowmeter 1 is measure-calibrated, the measuring test can be accurately and easily performed by comparing the measured value obtained from the flow rate data signal outputted from the communication control part 7 with a known flow rate value. Further, the measured data can be obtained even from a distant point when connection to the point is realized by a communication line.

摘要： PURPOSE:To prevent exhaustion of a battery for power supply of a gas shutting- off device by reducing the number of times for repeating shutting-off action. CONSTITUTION:A flow amount calculating unit 2 calculates an actual flow amount P upon receiving a flow amount signal G from a flow amount measuring means 1. A flow amount judging unit 4 makes its judgment by comparing a shutting-off value D held by a data holding unit 3 with the actual flow amount P from the flow amount calculating unit 2 and outputs a shutting-off/warning signal R. A shutting-off/warning means 5 issues a warning information and shuts off a gas passage based on the shutting-off/warning signal R. An answer signal detecting means 6 outputs an answer signal A when it detects nonshutting- off even during a shutting-off sequence. A count processing unit 7 allows output of the shutting-off signal until counter number of the answer signal A reaches its specified number.

摘要： PURPOSE:To improve the safety and reliability of the device by changing a stop deciding method corresponding to the condition of actually using an individual equipment. CONSTITUTION:The flow rate of the individual equipment to be used is previously stored in an individual flow rate storage equipment to be means 4. An individual equipment estimating means 2 estimates the individual equipment from the increase/decrease of the flow rate outputs an estimated individual arithmetic flow rate. When this estimated individual arithmetic flow rate is not contained in the individual flow rate stored in the individual flow rate storage means 4, an abnormal flow rate decision part 5 outputs an individual abnormal signal to an alarming means or stopping means 6. Corresponding to the time of the estimated individual arithmetic flow rate or the reset of an alarm, a normal individual flow rate registering means 7 stores this estimated individual flow rate in the individual flow rate storage means 4.

A time count completed signal is outputted from a referential time count unit 5 for counting a referential time from its valve closing operation, and an earthquake extinction signal is outputted by the earthquake judging unit 3. As a result, a reset signal is outputted by an abnormal condition completion judging unit 6, and thereby, the shut-off valve 7 is closed by the shut-off valve driving unit 4.
