Measuring Medium
XML type is normal-type, it adopts brass material, and generally used in the scope of non-corrosive gases.
XMF type is anticorrosive-type, it adopts stainless steel material, can measure corrosive gases.
Usage
- Put the meter on the worktable, adjust screws to enable blister of leveler in the centre, and maintain for a long time in use.
- Open sealed screw cap of water level controller, pull out internal wool rope.
- In the plug jack of thermometer or manometer, inject distilled water into the meter, when redundant distilled water drain from hole of water level controller ( sometimes it is clean when outflow one drop), then put wool rope in sealed screw cap of water level controller, and fasten the sealed screw cap.
- Install thermometer and manometer, (every case 10Pa)
- Connect air channel according to direction of gas outlet and intake, and sealled.
- Open gas valve, and then you can measure gas.
Attentions while using
- When you use it, you must always pay attention to the water level in the meter, otherwise it will affect measuring accuracy.
- When you use it, temperature should be maintained at 15 ~ 25 ℃, and the temperature is the same as room temperature, its temperature difference should be ≤ 2 ℃.
- You’d better readout in a few weeks after the operation of the meter.
- When pressure of measuring gas is go beyond normal pressure 1 ~ 6 times (1 ~ 6 KPa), the meters can still work, at this time manometer should be removed , then use rubber plug plugs up mounting holes of manometer.
- When flow of measuring gas is go beyond rated flow, the meters can still work, but measuring accuracy will be greatly decreased.
- The meter should not be installed in a cold room, for fear that it will freeze inside.
- In normal circumstances, check out accuracy every year at least.
Accessories
- 1 pc of thermometer
- 1 pc of manometer
- 2 rubber plugs
