※1 “P” in the model name means “I-type leakage detector”.
※2 EY25MTP-YL can set the number of small leakage flow detection within 1-30days. To change the setting, please change the number of day at the central monitoring system or a the setting device.
※3 Notification pattern of 2 linked external devices is only available for SY25MTP-YL.
※4 The communication will be “security data” similar to S-Type safety gas meter.
Basic Functions Note 1: Communicated as “security data” as well as the S type security meter.
Position on the law of Liquefied Petroleum Gas Act of the leak detector (I) type leak detection equipment.
The leak detector (I) type monitors the presence or absence of flow of gas the time when gas use stops (ie. late at night), and detects leakage of the supply piping. In addition, the built-in pressure sensor detects setting pressure and abnormal lock-up pressure.
1) Can be used as an alternative measures for inspecting supply piping leakage. (Ministry ordinance supplement standard section 29)
2) As complementary equipment of security ensure equipment obliged to authorized sales companies, in addition to the micro-leakage detection function, equipped with setting pressure and abnormal lock-up pressure detection functions. (Section 2, article 1 notice to determine the details of such as installation of security ensure equipment involved in licensing LP gas sales companies)
