Second, product features:

 

1. High accuracy, generally up to ±1%R, ±0.5%R, high-precision up to ±0.2%R;

 

2. Good repeatability, short-term repeatability can reach 0.05%~0.2%, it is because of good repeatability, such as frequent calibration or online calibration can get very high accuracy, is the preferred flowmeter in trade settlement;

 

3. Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;

 

4. Can obtain a high frequency signal (3~4kHz), signal resolution is strong;

 

5. Wide range, large caliber up to 1:20, small caliber 1:10.

Second, installation matters:

 

1. Before putting into operation, the instrument coefficient should be set first, carefully check to ensure that the flow meter wiring is correct and well grounded before it can be powered;

 

2, regularly clean, check and re-calibrate the flow meter, the flow meter with lubricating oil or cleaning liquid injection port, should be regularly injected with lubricating oil or cleaning liquid according to the requirements of the manual, in order to maintain the good operation of the impeller;

 

3, monitor the condition of the display instrument, evaluate the reading of the display instrument, and check in time if there is an anomaly;

 

4, keep the filter unblocked, the filter blockage can be judged from the increase of the difference in the reading of the pressure gauge at the entrance and exit, and the blockage can be eliminated in time.
