Selection and matters needing attention:

1. Battery powered electromagnetic flowmeter must configure grounding ring,ensure good grounding.

2. If the meter is installed in the easily flooded position,or installation position may be water position in the rainy day,the best choice of split type electromagnetic flowmeter and IP*8 protection grade,so as to avoid

because of rain water damage to the converter.

3. When the user in the selection of flow meter,try to make the flow velocity is larger than the above 0.5m/s,so both energy saving and can guarantee the best working range flowmeter.Please refer to the flow range table

 

4. For safety considerations,pulse output only for equipment calibration,KKF***0 electromagnetic flow

meter pulse output in the insulation is only functional insulation.This way please pay attention in selecting

the output.

 

5. KKF***0 series flowmeter have no 4~*0mA signal output.

 

6. If using RS**5 communications,need supply 5V DC power to flowmeter,otherwise the battery will be

difficult to long-time support for RS**5 communication.

 

7. If you use the GPRS communication,need to buy the GSM module.The data is a message pack form

transmission to the network
