Usage and precautions of oil-water interface instrument

　　1) When installing and using, pay attention to sealing and moisture-proof.

　　2) Oil and air have similar measurement properties.

　　3) The distance between the measuring rod and large metal structural components should be greater than 20mm.

　　4) The working power supply and control power supply should meet the voltage level requirements of the oil-water interface instrument.

　　5) The control output cannot be short circuited. Default output state: C1 and C2 open circuit when the oil-water interface is below the lower limit, and C1 and C2 short circuit when it is above the upper limit. Maintain the original state between the high and low limits. Making "output settings" can reverse the output status.

　　6) Metal containers should be grounded. The instrument casing should be electrically connected to the metal container.
