WARNING
When using combustible gas, install the device upstream of the safety shut
off valve. If air somehow enters the piping, and the sensor makes a spark due
to some cause like a lightning strike when an explosive mixture is present, an
explosion could occur inside the pipe.
On flanged models, do not use the device or installed pipes as a footrest.
Doing so might damage the device or piping, or cause a slip which might
result in injury.
Flanged models are heavy. Dropping them on your feet may cause injury.
The device is intended for use with fuel gas 13A, air, propane, and butane.
Do not use the device for other types of gases. Use of the gases having an
ignition temperature lower than 365°C may cause an internal pipe explosion.
A heater incorporated in a sensor could act as an ignition source if air has
entered the piping and explosive mixed gas is produced.
Use the analog outputs and alarm contact outputs on the device for
monitoring the gas flow rate of a burner or other equipment. Do not use these
outputs in applications where safety will be impaired when an analog output
abnormality or alarm contact output malfunction occurs.
Before removing, mounting, or wiring the CMG, be sure to turn off the power
to the CMG and all connected devices. Failure to do so might cause electric
shock.
CAUTION
Be sure to use this product within the flowrate range stated in the
specifications. To prevent excessive flow, use a suitable means to control the
supply pressure or use a throttle valve or the like to control the flowrate. If
the flowrate exceeds the upper limit, both the flowrate display and the output
voltage/current may indicate considerably lower values than the actual
flowrate.
If damage could result from the abnormal functioning of this device, include
appropriate redundancy in the system design.
This device is a precision instrument. Do not drop it nor subject it to shock.
Doing so might damage the device.
