III. Operation

When sensor is used, the liquid to be measured shall be clean and free of

◆

impurities such as fiber and granules.

◆ When sensor is used, it shall be at first slowly filled with liquid, then open the

outlet valve (which should be installed behind the flow meter). It is prohibited to

render the sensor under impact of high-velocity fluid when it is not filled with liquid.

◆ The maintenance interval for sensor is in general half a year. In case of

maintenance and cleaning, attention shall be paid not to damage the parts in the

measuring cavity, particularly the impeller. During assembly, watch carefully the

positional relation between guide part and impeller.

◆ When the sensor will be out of service for a long time, the internal liquid shall be

cleaned. After dried, the sensor shall be provided with protection sleeves at both ends

to protect against dust and it shall be placed in dry conditions for storage.

◆ The associated filter shall be cleaned on regular basis and the internal liquid shall

be cleaned when it is out of service for a long time. Similar to sensor, the filter shall

also be provided with dust protection and stored in dry conditions.

◆ The transmission wire of sensor may be overhead or buried (iron bushing shall be

provided in the latter case).

◆ Prior to installation of sensor, the connection thereof with display instrument or

oscilloscope shall be finished. Then switch on the power, blow the impeller with

mouth or move the impeller with hand to make it rotate quickly, see if there is any

reading. Install the sensor if there is reading. In case of no reading, the related sections

shall be inspected to eliminate any fault.

Warning:

Before wiring,cut off the external power.Wiring with electric is strongly prohibit.
