| Maintenance and Operation |
| |
Because the meter belongs to precise instrument, should handle with care during meter transportation, installation, storage and usage, and avoid overstress in installation; meanwhile, not change the relative position of indicator and transducer to ensure the meter accuracy;
There will be ferromagnetic particles deposited on the float in operating; if impurity is too much, it will block float deadly or affect measuring accuracy. Therefore, please clean pipe and float regularly. If necessary, mount magnetic filter at the meter inlet and clean it regularly;
Due to inside of indicator is electronic components, during disassembly the cover of housing, must tighten the screws of the cover and seal the housing to prevent harmful materials such as liquid ferromagnetic or corrosive gas entering the meter. At the same time, ensure housing grounded reliably;
When use the meter first time, should be care of following two points:
Liquid measurement: open valve slowly to avoid water head attacking the meter;
Gas measurement: before running, do not exert pressure on pipe, or if valve is opened suddenly, float would rush to brake to damage meter. Therefore, open valve slowly. Recommend a damping device to be equipped to reduce float vibration at utmost.
For intelligent remote indicator, first, ensure correct wiring, check up and then power on meter. Otherwise, easy to damage meter. Key operation must be conformed to the manual. If operate blindly, it will cause data stored in EEPROM lost or damaged;
Meter should be stored in place with temperature -40≧ - +55≧, relative humidity ＋90%, no sunshine and corrosive gas;
When open housing of explosion proof flowmeter to maintain on site, should turn off the power;
When ambient temperature is lower than -30≧ or higher than 85≧, LCD may appears stasis or blind screen, however, LCD won¨t damage under this condition; when temperature reverts to normal range, LCD display normally.
