Selection of rated pressureThe actual maximum working pressure must be less than the rated working pressure of the flowmeter.Selection of working temperatureThe maximum working temperature and minimum working temperature must meet the humidity requirements specified by the flowmeter.Selection of grounding ringThe product adopts the structure of grounding electrode, which can effectively ensure grounding for a long time and ensure the measurement accuracy in general. Therefore, the grounding ring is generally no longer needed. If the stray current is too large, such as the leakage current of the electrolytic cell along the electrolyte affects the normal measurement of the electromagnetic flowmeter, it is recommended to have a grounding ring.Selection of protection gradeIP67: Immersion type, suitable for integrated machine and split sensor. IP68: Submersible, working in water for a long time, suitable for split sensor.The split converter is IP65. The protection level should be selected according to the actual situation: the sensor is installed below the ground, and if it is often soaked in water, IP68 should be selected; When the sensor is installed above the ground, IP67 should be selected.Selection of additional functionsThe basic type of KEFT intelligent electromagnetic flowmeter has the functions of display, output (4~20)mA, 0~1kHz and alarm. Other additional functions can be selected according to the actual situation. Split installation: the sensor needs to be installed below the ground or for other reasons, so the split installation method should be selected.RS-485 communication: If the flowmeter needs to communicate with other equipment, the RS-485 communication function should be selected.
