Intelligent LPG Meter (Model-SB)
Feature
Shut off by Cumulative, Increased Gas Flow
- Where the sudden massive flow or unusual cumulative gas consumption detected.
- Learning function according to the actual consumption enables to set shutdown condition from optimum three levels.
Shut off by Seismic Sensor
- Where level-5 Japanese seismic load detected during flaming, the built-in seismic sensor shall automatically shut off the valve.
Pressure Observation
- Built-in pressure sensor observes the gas pressure from regulator outlet to appliances. Where something deviated from normal condition, the indicator alerts. Where the pressure drastically dropped, built-in shutoff valve closed.
Interlock with gas detector located close to the appliance & Power-off alarm
- Because of commercial use, SB meter is designed on condition of the interlock with the gas detector.
(Continuous usage time shutdown function is provided with Only SB4 so that no interlock with the gas detector is required while the such function works. - Where the power is off i.e., plug pulled out from receptacle, the meter alerts.
Remote Management System (Optional Service)
- Where the meter connected to the monitoring center via telecommunication line, the periodical meter reading, the remaining gas in cylinder management and user protection management from accidents caused by gas are available.
- Open-Close operation for shutoff valve is available for SB4 and 6, which contains the bidirectional motor valve, from the monitoring center via telecommunication line.
Precaution
- Do not disassemble or modify the meter. Those activities may cause malfunction or gas leakage.
- Installation shall be carried out by the qualified plumber. After the installation, conduct the pressurized leakage test and keep in file.
- Do not use the meter affected by shock due to drop or something similar situations.

* Extention-2
Extention-2 can be usable where the gas detector connected.
Where no gas detector connected, standard duration or extention-1 is usable.
