The structure of the intelligent integrated turbine flowmeter is explosion-proof design, which can display the total flow, instantaneous flow and flow full percentage. The battery adopts long-acting lithium battery. The service life of the single-function totalizer battery can reach more than 5 years, and the service life of the multi-function display meter battery can also reach more than 12 months.

The intelligent integrated meter can display a large number of flow units. In cubic meters, gallons, liters, standard cubic meters, standard liters, etc., fixed pressure and temperature parameters can be set to compensate for gas. In cases where pressure and temperature parameters change little, the meter can be used for fixed compensation integration.

The following points should be paid attention to in the maintenance of the sensor part of turbine flowmeter:

Use and adjustment

◆ When in use, the tested liquid shall be kept clean and free of impurities such as fibers and particles.

◆ When starting to use the sensor, fill the sensor with liquid slowly before opening the outlet valve.

It is forbidden for the sensor to be impacted by high-speed fluid when it is in a liquid-free state.

◆ The maintenance period of the sensor is generally half a year.  During maintenance and cleaning, please pay attention not to damage the parts in the measuring chamber, especially

Not the impeller.  Please watch the positional relationship between the guide and impeller during assembly.

◆ When the sensor is not in use, the internal liquid shall be cleaned, and protective covers shall be added at both ends of the sensor to prevent dust and dirt from entering.

And then store in a dry place.

◆ The filter used shall be cleaned regularly. When not in use, the internal liquid shall be cleaned. Like the sensor, it shall be equipped with dust cover and kept in a dry place.

◆ The transmission cable of the sensor can be laid overhead or buried (iron pipe shall be sleeved when buried).  )

◆ Before installing the sensor, connect with the display instrument or oscilloscope, switch on the power supply, blow the impeller with the mouth or hand to make it rotate rapidly to observe whether there is any display, and then install the sensor when there is.  If there is no indication, all relevant parts should be checked to eliminate the fault.
